T

he mining industry has forever been subject to the consequences of international relations and politics – not to say the uncertainties caused by domestic policies in the era of resource nationalism. The recent decay of the post-war, rules-based order, together with the race for critical minerals, have taken that uncertainty to a different level.

These challenges have been amplified by the trade wars sparked by tariffs introduced under the Trump administration. The effect of those tariffs on the movement of critical minerals around the planet has yet to be definitively determined, but the need to secure supply chains has never been greater. Probably the greatest shift has been the perceived need to reduce reliance on Chinese exports. This has become especially critical in the case of resource-constrained Europe, but the issue also resonates in the US which, by common consent, is many years behind China in both sourcing mineral supplies and facilitating processing.

Just a few examples illustrate the problem – China controls more than 90% of global supply of processed graphite, manganese, and rare earths, and more than 70% of cobalt and lithium. In a level playing field within a free trade environment, this would not necessarily be an issue. However, China (and other countries) have not been afraid to use mineral dominance to reinforce political and economic imperatives. Most recently, China used its dominance in lithium mining and processing to trigger fluctuations in price. Its dominance in the supply of processed energy transition metals has the potential to cause chaos in supply chains – neither the US nor anywhere else will come close to challenging China’s dominance for many years to come.

Several Gulf nations, now with significant financial firepower and a desire to play a bigger role on the international stage, are having an impact across the industry. In the case of Saudi Arabia this has been in an attempt to boost investment in its domestic mining potential (mining is the third pillar of Saudi’s Vision 2030). In Saudi and other Gulf states, taking advantage of cheap local energy to develop metal processing infrastructure has seen significant investment. For many Gulf nations with sovereign wealth funds – in particular Saudi, Abu Dhabi, and Qatar – capital has been deployed to invest in the mining industry globally, particularly in Africa but also in South America (for example Manara’s investment in Vale’s base metal subsidiary).

A further example of geopolitical influence on the mining sector can be seen in the Sahel region of Africa, where terrorist activities have posed challenges for mining projects – particularly gold – in Burkina Faso, Mali, and elsewhere. Their emergence has no doubt been assisted by the breakdown in stable government and, in the case of Francophone countries, a fracturing of the relationship with France (since 2020 there have been six successful coups across the region). The Global Terrorism Index reported that in 2024 Burkina Faso was the country most affected by terrorism globally, repeating its position in 2023. Mining provides a lucrative source of revenue for these groups so, without effective military intervention, this is a problem which is not going to go away. Suggestions that Russia – including the Wagner group – might enable some stability appear to be wide of the mark.

These are just three examples of how geopolitics is impacting the mining industry. There are many more – and the current global political climate suggests those impacts are unlikely to fade.

PROdUCT NEWS TAKRAF Group strengthens its South American presence with a key DELKOR Flotation Cell contract and commissioning of a test centre

T

AKRAF Group’s liquid/solid separation technologies, marketed through the DELKOR brand, are gaining momentum in the South American market, with the award of a significant order from a major Brazilian mining and iron ore company and the inauguration of a pilot plant and laboratory facility.

The order from the Brazilian company represents an important breakthrough for DELKOR’s BQR flotation technology in one of the world’s most competitive mining markets. It includes the supply of 24 DELKOR BQR200 and 12 DELKOR BQR300 Flotation Cells. The decision by the mining company to replace its existing technology, which had been provided by another company, with the DELKOR cells was based on successful testing of DELKOR’s proprietary MAXGen™ mechanism in one of the mine’s existing flotation cells.

Since their launch in 2020, the new generation DELKOR BQR Flotation Cells have been adopted globally for their high metallurgical efficiency, reliability, and adaptability. Equipped with the MAXGen mechanism, they improve metal recovery while reducing power consumption and cost of ownership and offer greater ease of maintenance.

Developed through extensive research, MAXGen generates a swarm of air bubbles with optimum size distribution.

A careful trade-off between agitation levels and the bubble

distribution facilitates the flotation of fine and coarse particles equally, which is especially relevant for the flotation of low-density minerals, while efficiently keeping solids in suspension. This maximises bubble-particle interaction and improved flotation kinetics.

The cells are used in roughing, scavenging, cleaning, and re-cleaning applications to process a range of commodities from copper, zinc, and platinum group metals to phosphates, graphite, slag, and effluents. Key design advantages include a rotor-stator configuration that allows lower tip speed to reduce operational costs from lower wear and power consumption. Air is introduced through the rotor shaft for precise control over air flow and distribution, with adjustable airflow and froth-crowder settings. Custom launder designs ensure optimal lip loading and froth carry rates, while optional internal or external dart valves enhance safety. Other features include precise froth level control instruments and cell bypass, which improves circuit flexibility and, for larger cells, facilitates quick, easy, and safe cell maintenance.

The DELKOR BQR Flotation Cells range in sizes from 1.5 m³ (BQR15) to 300 m³ (BQR3000). In addition to new installations, they can be retrofitted into units from other OEMs. This offers mining companies a fast-track method to improve recovery rates and reduce operational costs.

In a significant move to strengthen DELKOR’s presence in the South American market, TAKRAF Group recently inaugurated, in partnership with the Gorceix Foundation, a flotation cell pilot plant and a comprehensive laboratory for conducting various liquid/solid separation tests. Based in Ouro Preto, Brazil, this is the first TAKRAF Group pilot facility of its kind globally.

A significant feature of the pilot plant is its industrial scale. This provides customers with the confidence that the results achieved during testing will be replicated in the field, as opposed to making decisions based on tests that may not be representative.

The new laboratory, the largest of its kind in Brazil, will enable a full suite of tests, including filtration, rheology, and static and dynamic sedimentation analysis. These tests are key to the optimal selection and sizing of liquid/solid separation equipment – such as DELKOR Thickener and DELKOR Filter Press.

TAKRAF Group is celebrating its 300-year anniversary this year, having evolved from an iron hammer mill, established in 1725. Having grown exponentially over time, contributing many industrial and technological milestones, TAKRAF Group is, today, a major global company serving the mining and related industries, with a presence in 14 countries on six continents.

10 November/December 2025 // global mining review

Sushmita Vazirani, Wood Mackenzie, examines how South Africa is navigating the twilight of thermal exports.

A

s seaborne demand begins its descent from peak levels, South Africa – once a cornerstone of international coal trade – faces mounting challenges. These illuminate broader trends reshaping energy markets worldwide.

Peak coal’s aftermath

Seaborne thermal coal exports will fall from 1.080 billion t in 2024 to approximately 1.015 billion t in 2025. This decline stems primarily from a 60 – 65 million t reduction from China. The shift signals coal’s structural retreat from global energy systems.

Yet this transition proves far from uniform.

Climate imperatives and technological

advances drive long-term decline. Near-term dynamics reveal surprising resilience in specific regions. India and Southeast Asia continue modest growth trajectories through 2040.

China maintains substantial domestic production to reduce import dependence.

South Africa exemplifies these contradictions.

The country produces approximately 235 million t annually – 98% classified as thermal coal. The Mpumalanga Central Basin accounts for 79% of total output in 2025.

The Witbank (eMalahleni) coalfield represents the largest producer. It accounts for 56% of South Africa’s total marketable production in 2025. The Highveld coalfield

global mining review // November/December 2025 11

follows at 22%. Witbank’s contribution gradually decreases as major global companies divest and key mines approach depletion.

Wood Mackenzie’s asset-level analysis shows South African marketable coal production declining from 238 million t in 2024 to 209 million t by 2030. This reflects mine closures in depleting reserves rather than demand destruction.

Navigating structural headwinds

Three critical challenges reshape South Africa’s coal landscape. These include reserve depletion, infrastructure constraints, and financing difficulties.

Figure 1. Khanye Colliery, 2025 – Sushmita Vazirani (Principal Analyst, Wood Mackenzie).

Reserve depletion emerges as the primary threat.

Several major Australian coal mines face depletion by 2035. Key Indonesian basins confront similar timelines.

The 2030s usher in faster resource depletion, sparking need for new capacity.

Beyond 2030, remaining coal lies deeper underground in thinner seams or remote locations. This dramatically increases extraction costs. A race emerges between declining demand and reserve depletion. Supply in the long term becomes a contest between these opposing forces.

Infrastructure bottlenecks compound these challenges.

Over the past three years, Transnet Freight Rail’s performance has deteriorated significantly. It has fallen well below 60 million t annually. South Africa compensates through road transport to minor terminals – RB Dry Bulk, Matola, and Durban. This becomes unsustainable when seaborne prices fall below US$100/t.

Wood Mackenzie estimates total coal exports from minor terminals will fall from their peak of 19.1 million t in 2023 to 12.6 million t in 2025. Major South African producers remain locked into 10-year rail and port take-or-pay contracts until 2025. Contract renewals still underway appear unlikely at current volumes.

Financing constraints create the third major hurdle.

ESG scrutiny has eliminated traditional project finance for coal developments. Equity funding shortages mean coal-related projects face increased scrutiny from institutional investors. Self-funding and non-disclosed partnerships now play important roles in project finance.

Despite these challenges, South Africa maintains competitive advantages. Wood Mackenzie estimates average export total cash costs at US$65 – 68/t in 2025.

This represents a 2% y/y increase compared with 2024.

Local currency depreciation has preserved competitiveness over the past decade.

Transformation through transition

Figure 3. Y/y change in base case seaborne supply (million t). Source: Wood Mackenzie Thermal Coal Markets, September 2025.

12 November/December 2025 // global mining review

The evolving landscape reveals fundamental shifts in coal market dynamics. Quality premiums increasingly matter as buyers prioritise efficiency over cost considerations.

High-CV suppliers gain market share whilst low-grade producers face margin compression.

Indonesia faces visible pressure. The country has long anchored global thermal supply particularly in low-CV grades. January-August shipments have been approximately 34 million t lower y/y. Higher domestic production in China and India squeezed import demand.

Meanwhile, high-CV suppliers receive relatively better support. Resilient demand from Japan, South Korea, and Taiwan drives this trend. By 2050, Pacific suppliers are expected to strengthen their positions despite overall market contraction. Indonesia is set to lead exports despite decline whilst Australia is expected to gain market share as high-CV demand grows.

Environmental considerations add complexity. Scope 1 and 2 emissions from global seaborne coal mines range widely. They span from around 9 kg/t CO2e to over 700 kg/t CO2e. This variation creates differentiation opportunities for lower-emission producers.

South Africa benefits from this trend.

Exports return to traditional Asian markets led

by India. However, competition with Indonesian suppliers for declining demand will intensify over the long term.

Charting the descent

Wood Mackenzie forecasts total exports to fall below 60 million tpy in 2027 – gradually declining to approximately 25 – 30 million t by 2050.

Wood Mackenzie estimates seaborne Figure 4. Coal mines in South Africa – LENS map.

I

t is clear why long-term equipment stability is so highly valued within the mining sector. Operators need machines that return value on investment, can operate reliably for a long time in harsh conditions, and experience as limited amount of unexpected downtime as possible.

The engine is critical to overall equipment performance, which is why Cummins takes the long view when it comes to its support model for miners, combining a century of engineering expertise with their extensive service network to deliver powerful performance throughout the entire

14 november/december 2025 // global mining review

engine lifecycle. How this plays out in the field can be seen in several ways.

Extending engine life through data and collaboration

Extending the operational life of engines is one of the most effective ways to improve productivity and reduce costs. Put simply, a long-lasting engine benefits miners in one of two ways – either through fewer rebuilds within the total machine life, or by extending the length of total life.

Sean Lynas, Power Systems Industrial Markets Director, Cummins, UK, reviews the importance of long-term partnership and smart optimisation for extending the operational life of engines.

Cummins achieves this by collecting real-world data and applying engineering insights to optimise engine performance and reduce wear.

The QSK60 engine used in large mining excavators is a prime example of this approach. Originally rated for 12 000 hours under typical load conditions, Cummins extended its life to overhaul to 18 000+ hours through a combination of rigorous durability testing, component optimisation, and refined maintenance practices. These improvements are based on collaborative customer projects that allow engineers to further optimise for the challenges of specific mining environments.

Having fewer rebuilds due to extended engine life also means having less downtime and lower total operational cost, providing greater value to mining operators. This approach demonstrates that combining engineering expertise with field insights can unlock substantial benefits over the engine’s operational lifetime.

To keep fleets performing as expected, miners require real-time visibility into in-field equipment operating conditions. Modern connected systems enhance this visibility, delivering real-time insights.

PrevenTech® remote monitoring

Cummins’ PrevenTech is a smart, integrated engine reliability and performance solution that combines real-time data monitoring, advanced predictive analytics, and 24/7 expert support to ensure Cummins engines

operate at peak performance. Connected engines transmit alerts for urgent or potential issues, along with recommended maintenance actions based on real-world usage.

PrevenTech enables operators to: � Optimise maintenance intervals for each site, using data insights to hone performance. � Track component wear to identify what servicing is required for maintenance, maximising uptime. � Monitor engine health remotely to predict maintenance requirements ahead of potential engine failures. � Proactively plan downtime and repairs to minimise disruption.

Even with the best preventative measures, engines require routine maintenance. Repair and maintenance needs – especially when unexpected – can be difficult to manage, a challenge made easier through accessible support.

Global coverage and PowerCare™ Cost Per Hour (CpH)

Cummins supports engine longevity and reliability not only through product design and advanced analytics, but also through its extensive global service network, spanning 190+ countries across six continents through 600+ distributor locations, 3700+ certified high-horsepower technicians, and 17 high-horsepower master rebuild centres.

global mining review // november/december 2025 15

Part of Cummins’ commitment to offering service programmes and options that fit every mine site’s needs includes its customisable PowerCare™ CpH contracts, which provide predictable maintenance costs, covering parts, labour, and scheduled or unscheduled maintenance over the engine lifecycle. Customers using CpH and Cummins’ global service network can achieve over 97% engine availability.

By forecasting maintenance costs related to repairs, mid-life, and rebuilds, miners can operate with reduced operational risk.

With or without CpH contracts, Cummins maintains a robust inventory of ‘swing’ – or replacement – engines to keep mine sites up and running while service is under way.

Expert rebuilds Figure 1. Cummins extended the life of its legendary QSK60 to 18 000+ hours through a combination of rigorous durability testing, component optimisation, and refined maintenance practices.

Figure 2. Cummins launched an updated PrevenTech platform in April 2025. Designed for Cummins engines by Cummins experts, PrevenTech features proprietary datasets, only interpretable by Cummins, and 24/7 Cummins Care support.

Part of the beauty of Cummins engines is that they are built to withstand 3+ rebuild cycles. When rebuilds are required, it is important to invest strategically to return the best long-term value possible.

Cummins’ global network of 17 high-horsepower Master Rebuild Centres (MRCs) extend the life of high-horsepower engines, including long-time favorites like the QSK38, QSK50, QSK60, and more. Through a six-stage process, engines are disassembled, cleaned, inspected, re-machined, re-built with genuine Cummins parts, and tested to meet or exceed factory standards, as rebuilt units include a rebuild warranty included on rebuilt units Rebuilds provide a cost-effective option to enhance operational efficiency, reduce environmental impacts, and maximise the value of existing assets without the expense or downtime of replacing engines. While rebuilds take an average of 35 hours, they occur while the machine resumes operation with a Cummins-provided swing engine. Cummins’ HHP MRCs also support Cummins’ sustainability goals by using 85% less raw materials than new engine production, reusing water, and minimising scrap.

Approaching a rebuild also provides the opportunity to consider new ways to tailor equipment to mine profiles and generate greater efficiency.

Custom engine calibrations

Cummins site-specific calibration upgrades for engines in the QSK38 to QSK95 range optimise combustion and fuel delivery for specific duty cycles. By measuring factors like site profile, average loads, tyre pressures, operating temperatures, and driver behaviours, Cummins can build a holistic data set and make calibrations that reduce engine fuel consumption and CO₂ emissions by 2 – 5% without compromising reliability or productivity.

For operators, these upgrades can deliver measurable fuel savings while maintaining familiar engine performance, providing an immediate impact on operational costs and environmental goals. For those wanting to go further, hybrid options provide a future solution.

Hybrid electric vehicles (HEVs)

Hybrid retrofit programs combine internal combustion engines with battery-electric systems, providing flexible energy management across mining haul routes.

Hybridisation presents significant opportunity for the mining industry’s effort to achieve an energy transition, leveraging the large installed asset base.

Hybrid systems allow operators to: Capture energy through regenerative braking.

Use battery power during low-demand periods.

Reduce fuel consumption and CO₂ emissions by 15 – 30%, depending on mine profile.

Reduced engine loads also lower maintenance frequency and could extend engine life. Cummins’ first-fit hybrid pilot programme launched in 2024, and the acquisition of First Mode assets in 2025, expanded hybrid retrofit capabilities at scale.

Early deployments include Komatsu 930E-4 trucks in Chile, with additional pilots planned across North and Latin America.

Hybrid systems provide reliability and operational familiarity for operators while delivering fuel and emissions savings, demonstrating a practical pathway for incremental decarbonisation without the need for full electrification.

Dual-fuel ethanol/diesel systems

Cummins is also furthering the ‘clean fuels’ decarbonisation pathway, which will also be available through retrofits for existing fleets. Cummins, in partnership with Vale and Komatsu, is developing dual-fuel systems that allow haul trucks to operate on a combination of ethanol and diesel.

Modified trucks can run on up to 70% ethanol, potentially reducing CO₂ emissions by up to 50%.

Engine testing continues through 2026, followed by field validation. Dual-fuel systems leverage existing infrastructure and fleets without major modifications, making them a cost-effective option for operators seeking significant emissions reductions.

Drop-in fuel integration

Figure 4. A technician at Cummins’ newest high-horsepower MRC in Krakow, Poland, works on a Cummins engine rebuild for a Komatsu customer.

As part of efforts to support the decarbonisation of mining today, Cummins engines already support the use of drop-in fuels such as hydrotreated vegetable oil (HVO) and biodiesel blends. These fuels can be used with existing engines and infrastructure, avoiding high capital expense associated with alternate solutions while advancing decarbonisation goals.

For example, hybrid engines running with 55% HVO can achieve up to a 50% CO₂ reduction from well-to-wheel.

Drop-in fuel integration allows operators to reduce their environmental impact without major modifications to fleet or facilities, enabling significant emissions saving without high costs and integration timings.

A balanced path forward

Figure 5. Cummins and Komatsu recently announced a memorandum of understanding (MOU) to collaborate on the development of hybrid powertrains for surface haulage heavy mining equipment.

18 november/december 2025 // global mining review

Internal combustion engines remain the foundation of powering mining, given fleet requirements, current infrastructure limitations, and remote operating locations.

Miners can protect their investment in these high-horsepower power solutions through strategic partnership for long-term aftermarket support and technology upgrades through the life of these engines.

By combining proven engine technology with emerging solutions, Cummins maximises engine life and operational reliability, while also providing a practical pathway to emissions reduction.

Anu Niittynen, Sandvik Mining, USA, details the role of the iLink Data Interface in modern mining systems.

A

s the mining industry undergoes a profound transformation driven by automation, digitalisation, and sustainability imperatives, the ability to integrate equipment into a unified digital ecosystem has become a cornerstone of operational excellence.

In surface mining, rotary drilling operations are among the most data-intensive and

operationally critical processes. They serve as the starting point for the entire value chain – from ore extraction to processing and logistics.

Consequently, the interoperability of drill rigs with mine planning, monitoring, and reporting systems is essential for achieving real-time visibility, process optimisation, and data-driven decision-making.

global mining review // november/december 2025 19

To address this need, Sandvik has developed the iLink Data Interface, a standards-based, vendor-neutral communication layer that enables secure and efficient interaction between Sandvik iSeries surface drill rigs and third-party mining systems. Built on REST web services and HTTP protocols, iLink Data Interface provides a robust and scalable foundation for integrating drilling operations into broader mine automation strategies.

The digital transformation of surface drilling

Historically, rotary drill rigs operated as standalone mechanical systems, with limited connectivity and minimal integration with mine-wide IT infrastructure. Operators manually uploaded drill plans, recorded performance data on paper or local storage, and relied on radio communication for coordination. This siloed approach limited the ability to optimise drilling performance, respond to changing geological conditions, or ensure alignment with dynamic mine plans.

Today, rotary drill rigs are increasingly equipped with advanced onboard control systems, GNSS-based positioning, real-time telemetry, and onboard/remote automation features (such as auto-drill and auto-levelling). These capabilities generate vast volumes of operational data, including penetration rates, torque, and measurement while drilling (MWD) parameters. At the same time, rigs require continuous input from centralised systems – such as updated drill plans, configuration files, and safety protocols.

The challenge lies in enabling seamless, secure, and standardised communication between these systems. This is where the iLink Data Interface plays a pivotal role.

Technical architecture: RESTful design for industrial integration

The iLink data is architected using Representational State Transfer (REST) principles, which are widely adopted in industrial automation and enterprise IT due to their simplicity, statelessness, and compatibility with web technologies. RESTful APIs use standard HTTP methods to perform operations on resources, making them easy to implement and integrate across diverse platforms.

In the iLink implementation, external systems interact with the drill rig via HTTP requests, accessing structured data in JSON format. This eliminates the need for proprietary protocols or middleware, reducing integration complexity and enabling faster deployment. The interface is designed to be platform-agnostic, allowing integration with a wide range of systems, including: Mine planning software (e.g. Deswik, Hexagon, MinePlan).

Fleet management systems (e.g. Wenco, Modular).

Data analytics platforms (e.g. Power BI, Tableau).

Cloud-based IoT platforms (e.g. Azure IoT, AWS Greengrass).

Depending on the deployment scenario, communication can occur over local networks, VPNs, or cloud gateways. In remote or offline environments, physical connections may be required, but the communication model remains consistent.

Functional capabilities: A modular and extensible interface The iLink Web Interface exposes a comprehensive set of endpoints grouped into logical modules that reflect the functional architecture of the drill rig. These include:

System metadata and configuration

Access to rig identification, software versions, and hardware capabilities.

Read/write access to system-level settings, such as time synchronisation and operational modes.

Operator interface and equipment live monitoring

Read/write access to operator interface data, enabling remote visualisation of user interactions.

Real-time access to equipment signals, including hydraulic pressures, rotary speeds, feed force, and bit position.

Alarm and event logs for fault diagnosis and operational analysis.

Drill plan and geospatial data

Access to TIM3D drill plan files, including hole coordinates, depths, and collar positions.

Integration with mine design models for spatial alignment and compliance verification.

File transfer and document exchange

This modular design allows mining companies to implement only the functionalities they require, while maintaining the flexibility to expand integration as operational needs evolve.

Operational use cases: From planning to predictive maintenance

The iLink interface supports a wide range of use cases across the mining value chain, enabling both tactical improvements and strategic transformation.

Automated drill plan deployment

Mine planning systems can push updated drill plans directly to the rig, eliminating manual data entry and reducing the risk of errors. This is particularly valuable in dynamic pit environments – where geological conditions or production targets change frequently.

Real-time equipment monitoring

Maintenance and operations teams can monitor rig performance in real time, accessing live telemetry and alarm data. This enables proactive maintenance, reduces unplanned downtime, and improves asset utilisation.

Quality assurance and compliance

MWD data can be automatically retrieved and analysed for quality control, ore body modelling, and regulatory compliance. This supports faster decision-making and enhances transparency.

Integration with blasting and load/haul systems

By sharing drill hole data with blasting systems (e.g. Dyno Nobel), mining operations can optimise fragmentation and reduce overbreak. Similarly, integration with load and haul systems ensures alignment between drilling, blasting, and material movement.

Foundation for automation and AI

With programmatic access to machine data, iLink enables the development of advanced automation applications, including: Predictive maintenance using machine learning.

Autonomous drill scheduling.

22 november/december 2025 // global mining review

Integration with autonomous haulage systems.

AI-driven optimisation of drilling parameters.

Security, governance, and compliance

Given the critical nature of operational data, iLink incorporates robust security features, including: Authentication and authorisation: Role-based access control ensures that only authorised systems and users can access sensitive data.

Encryption: All data in transit is encrypted using industry-standard protocols (e.g. TLS).

Audit logging: All interactions with the API are logged for traceability and compliance.

These features support compliance with industry standards, such as ISO 27001, and ensure that data integrity and confidentiality are maintained across the mining enterprise.

Scalability and future-proofing

The iLink interface is designed to scale with the evolving needs of mining operations. As new sensors, automation features, or analytics tools are introduced, the API can be extended to support additional data types and workflows.

This extensibility ensures that mining companies can future-proof their digital infrastructure and adapt to emerging technologies without costly system overhauls.

Strategic implications for the mining industry

The adoption of interoperable interfaces like iLink reflects a broader shift in the mining industry towards open architectures, vendor-neutral ecosystems, and data-driven operations. By enabling seamless integration between equipment and enterprise systems, mining companies can: Break down data silos and improve cross-functional collaboration.

Accelerate the deployment of automation and AI. Enhance operational agility and responsiveness.

Improve safety, sustainability, and regulatory compliance.

In this context, iLink is not merely a technical solution – it is a strategic enabler of the digital mine.

The Sandvik iLink Data Interface represents a significant advancement in the integration of surface drilling operations into modern mining systems. By providing a standardised, secure, and extensible communication layer, iLink enables real-time data exchange, automation, and analytics across the mining value chain.

As the industry continues to evolve toward intelligent, autonomous, and sustainable operations, solutions like iLink will play a central role in shaping the future of mining – where every drill hole, data point, and decision is connected.

24 November/December 2025 // global mining review

Qu Shengli, President, Shandong Humon Smelting Co., Ltd., China, considers the century-long dilemma of gold smelting and outlines how a leading Chinese smelter has remained dedicated to technological innovation in the sector.

H

istorically, gold smelting has undergone four major technological revolutions. From the primitive gravity concentration and amalgamation process to the invention of the direct cyanidation method, the industry was able to exploit low-grade ores, spurring a surge in global gold production. Cyanidation became the industry standard process, laying the foundation for modern hydrometallurgy. However, the extreme toxicity of cyanide also sowed an environmental crisis that has persisted for

more than a century. The third-generation, single-stage roasting–cyanidation leaching process addressed the challenge of extracting gold from sulfur and arsenic-bearing complex ores, making refractory ores economically viable. It expanded the resource base from single gold ores to polymetallic associated ores, driving a transition from pure gold recovery to multi-element recovery.

The fourth-generation, pre-treatment– cyanidation process is still widely adopted by most Chinese gold smelters and has the

global mining review // November/December 2025 25

advantage of low capital requirements and short metal realisation cycles. Yet, it generates enormous amounts of cyanide-laden wastewater and tailings, causing serious environmental harm. At present, more than 70% of gold in China is refined using the cyanidation process.

In 2024, the country produced 534.1 t of refined gold, consuming an estimated 80 000 t of cyanide and generating over 195 million t of cyanide-bearing solid waste and 300 million m3 of cyanide-containing wastewater. Moreover, due to inherent limitations of the process, the recovery rates of valuable metals – such as gold and silver – from complex materials remain low, while associated elements cannot be effectively recovered, leading to significant resource wastage.

It is foreseeable that the continued large-scale reliance on cyanidation for gold extraction will create compounded pressures from both historical and new issues, particularly in the generation and treatment of cyanide solid waste and in ensuring safe production.

The traditional cyanidation process thus faces the

paradox of ‘easy extraction, difficult remediation, and low efficiency’.

Technological breakthroughs in cyanide-free metallurgy

Gold is a vital foundation of financial stability and a key strategic resource contested worldwide. Since its inception, Shandong Humon Smelting – a leading enterprise among China’s top 10 gold smelters – has positioned itself to serve national strategies as a specialised gold smelting enterprise.

How to shed the heavy burden of cyanide-based technologies and forge a truly cyanide-free and environmentally friendly ‘sword of extraction’ has long been a question for the gold industry. Humon’s technological breakthrough illustrates an adage: disruption often comes not from within the industry, but from the outside. Focusing on three core objectives –enhancing resource efficiency, reducing pollution and energy consumption, and adapting to complex multi-element ores – Humon abandoned traditional hydrometallurgical paths. Instead, it pioneered a fire-metallurgy route to cyanide-free smelting, becoming the first bold explorer in the industry.

Using its first round of funds raised after its 2008 IPO, Humon constructed a new facility and developed the world’s first oxygen bottom-blowing smelting with matte capture process. This created China’s first cyanide-free production system for processing complex gold concentrates. Remarkably, the system achieved successful commissioning at first attempt and full capacity in the same year. Its success not only removed cyanide – the industry’s toxic ‘tumour’ – from the process, but also raised gold Figure 2. Qu Shengli, President of Shandong Humon Smelting. recovery rates by 5 – 13% and silver recovery rates by 8 – 38%, ushering in a new era of pyrometallurgical gold refining.

Innovation has never ceased. In 2011, Humon pioneered a three-furnace continuous process combining bottom-blowing smelting, molten-state reduction, and oxygen-enriched volatilisation for lead-rich gold recovery.

Commissioned in 2013, the new process again set industry records: recovery rates for gold, silver, and lead soared; comprehensive energy consumption dropped by 65%; sulfur dioxide emissions fell by 95%; and carbon dioxide emissions declined by 80%. This achievement won the prestigious State Science and Technology Progress Award Figure 3.

Arsenic has long been regarded as an intractable challenge in gold and non-ferrous metallurgy.

Traditional arsenic capture methods often fail due to gas flow fluctuations and high SO₂ concentrations. In 2010, Humon launched a five-year R&D effort that produced an integrated process combining oxygen bottom-blowing matte capture with rapid flue gas cooling and dry arsenic collection. Achieving over 90% arsenic removal efficiency, the innovation solved a global problem of high-arsenic ore smelting. Humon further advanced the concept of resource-based arsenic treatment, developing an industrial chain from arsenic trioxide to metallic arsenic to high-purity arsenic – thus transforming pollution control into industrial value creation. This ‘Humon Model’ of arsenic management won the First Prize of the China Nonferrous Metals Industry Association’s Science and Technology Progress Award, as well as support from the National Development and Reform Commission’s Solid Waste Resource Utilisation programme.

Over 37 years, Humon has made ‘continuous innovation’ its core competitiveness, revolutionising gold metallurgy and constructing a complete cyanide-free, pyrometallurgical, environmentally friendly technology system. The company has won two State Science and Technology Progress Awards (Second Prize), 11 provincial and ministerial First Prizes, and has been named a ‘National Green Factory’ and ‘Advanced Unit of Resource Utilisation in Shandong Province’. Today, Humon stands as a vanguard of modern gold metallurgy. Each iteration of gold extraction technology has resonated with the progress of human civilisation. It is foreseeable that, as global competition for mineral resources intensifies and under the dual backdrop of carbon neutrality goals and major-power rivalry, cyanide-free metallurgy – with its irreplaceable comprehensive advantages – will become the mainstream of global gold smelting.

Transformation Project’, Humon overcame the challenge of comprehensively recovering valuable elements such as gold, silver, tellurium, copper, iron, and sulfur, thereby officially opening the door to multi-element recovery.

In 2013, alongside building the world’s first lead-carrier gold-silver recovery system, Humon further expanded into lead, zinc, and bismuth recovery.

In 2018, Humon successfully commissioned the ‘Harmless Treatment Project of Waste Residue from Gold Smelting’, turning cyanide tailings from gold and silver processing into valuable resources by recovering gold, silver, copper, and tellurium. This not only neutralised hazardous waste, but also advanced its resource-based utilisation, extending the comprehensive recovery chain and pushing toward the complete utilisation of mineral resources. That same year, to tackle the challenges of low recovery efficiency and high energy consumption, Humon launched the ‘Comprehensive Recovery and Utilisation Technology Transformation Project of Rare and Precious Metal Resources’. Working in collaboration with leading universities, the company overcame significant technical hurdles and succeeded in bringing multiple rare and precious metals – including bismuth, tellurium, selenium, platinum, and palladium – into full-scale production and industrial application.

Anchored in its cyanide-free core process, Humon has since established a comprehensive recovery system for ‘all-element extraction’, creating a product portfolio built on gold as the core, with multi-metal synergy.

Guided by the principle of ‘one mine, multiple recoveries; maximising resource utilisation’, Humon has transformed finite resources into virtually unlimited value. Today, its primary product matrix spans 17 elements, carving out a second growth curve for the gold smelting industry beyond the traditional model.

The strategic transition to comprehensive smelting

Conclusion

As easily processed high-grade ores are depleted, the share of complex multi-element ores continues to rise.

In China, about 70% of gold reserves – and globally, about 38% – are found in such complex concentrates.

They have become the primary raw material for future gold production. Focusing solely on gold, silver, copper, and lead would cause immense resource waste and economic loss. Meanwhile, cyanide-free technologies are advancing rapidly, with breakthroughs in key processes and equipment creating the technical conditions to break barriers between different metallurgical fields. Against the backdrop of global industrial restructuring, the gold smelting sector faces unprecedented pressure to transform. In response, Humon has proposed its ‘Comprehensive Smelting’ strategy: full recovery of valuable elements, green low-carbon operations, and zero waste. In 2010, with the successful commissioning of the ‘Complex Gold Concentrate Comprehensive Recovery Technology

28 November/December 2025 // global mining review

Innovation remains Humon’s lifeblood. In 2018, Humon extended its industrial chain into high-purity semiconductor and infrared optical materials. Driven by the ambition that ‘Humon’s height equals the world’s height, Humon’s purity equals the world’s purity’, the company has, after a decade of relentless innovation, developed seven major series with 29 high-purity and infrared optical products. Recognised as a leading new-materials enterprise in Shandong Province, Humon has become a renowned global supplier of advanced metal materials, an indispensable contributor to China’s ‘national strategic technologies’ and ‘intelligent manufacturing’.

As a visionary and responsible listed company, Humon will continue along the path of innovation, remaining aligned with global scientific frontiers, global resource utilisation, and human development. It will continue working to further advance gold smelting technologies, ensuring that more of its innovations benefit both the industry and society at large.

rica Digital Solutions’ ongoing digital expansion has sought to better connect the mining value-chain. This dedicated digital arm has delivered many well-known solutions and tools – such as the Integrated Extraction Simulator (IES) – that are becoming undoubtedly essential to mining operations.

Across the global mining sector, operations face a common set of pressures. Orebody variability, volatile

global mining review // november/december 2025 29

commodity markets, increasingly stringent ESG requirements, and the need to get more from existing assets all challenge traditional approaches to optimisation.

For many sites, the investment in optimisation studies is significant – but too often, the insights remain trapped in reports, disconnected from daily decision-making.

Without a way to translate theoretical recommendations into operational reality, improvements stall. Critical decisions on drilling, blasting, blending, and processing are made in isolation, leading to trade-offs between throughput and recovery with no clear resolution.

The industry needs tools that connect data, processes, and people across the value chain – and allow ‘what if’ scenarios to be tested before they are implemented. This is where the IES has proven itself as more than just a modelling platform – it is a decision-support system for an increasingly complex operating environment.

The evolution and capabilities of the IES

The origins of the IES lie in an industry-sponsored research programme led by Australian based Cooperative Research Centre for Optimising Resource Extraction (CRC ORE), which brought together mining companies, research bodies, and technology providers to develop a platform capable of simulating the entire mining value chain in a single, integrated environment. In 2021, Orica was selected as the commercialisation partner for the IES to bring it to market globally. Since then, Orica Digital Solutions has transformed it into an award-winning, browser-based application that combines advanced

simulation with machine learning to deliver practical, site-ready insights.

The IES has evolved as one powerful, fundamental platform with two integrated applications, IES Projects and ModelNet, working together to provide a seamless environment for processing insights and operational decision-making. IES Projects enables users to model, simulate, and optimise complex mineral processing flowsheets. ModelNet allows for the creation of machine learning models that can be embedded into equipment in the flowsheet and therefore into simulations.

Together, these tools form a connected ecosystem, with the IES acting as the central simulation engine that integrates data and insights from across the operation.

At its core, the IES combines physics-based equipment models with data-driven intelligence to simulate entire mining-to-processing chains or specific plant sections. It supports large datasets, multi-component modelling, and rapid configuration of alternative flowsheets, enabling mass simulation runs in hours rather than weeks. User-defined constraints keep simulations grounded in operational reality, while a diverse model library allows users to incorporate both industry-standard and custom-developed models. These initiatives are tested using block model data developed through geostatistical modelling, representing the life of mine (LOM), and utilising an integrated IES flowsheet.

The IES in action: From planning to plant performance

The IES has been deployed across a wide range of scenarios, from early-stage project evaluation to operational fine-tuning. In each case, it has provided the integrated view needed to connect cause and effect across the mining value chain – and deliver measurable results.

Powered by ModelNet, the IES also integrates machine learning, allowing users to build MetaModels that run scenario analyses 3000 times faster than traditional methods, with prediction errors as low as 0.45%.

Optimising strategic planning and feasibility

Figure 1. The IES is a collaborative tool that enables users to intergrate data and insights from across the operation.

A major copper operation needed to determine the most valuable combination of mine plan and plant configuration. Using the IES, the team simulated ore variability, processing constraints, and product quality targets in a single integrated model. This identified the block sequence and plant setup that would deliver the highest long-term value, avoiding suboptimal plans that looked viable when mining and processing were considered in isolation.

Recovering from downtime

Maximise throughput and energy efficiency

Optimise recovery and product quality

The selected approach regained the full shortfall within three weeks while keeping throughput and metallurgical performance at target levels.

Managing mid-project design changes

During construction of a nickel concentrator, late-stage equipment changes altered key design parameters. The IES re-ran the flowsheet with the new specifications, quantifying the impact on throughput and recovery. It then pinpointed process control adjustments to offset performance risks, helping the project avoid costly post-commissioning modifications.

Preparing for ore type transitions

A Western Australian gold mine was approaching a transition to harder ore in its pit sequence. The IES simulated the impacts from drill and blast through to grinding energy demand, allowing the operation to implement changes to liner design and mill speed ahead of time. This proactive approach prevented the expected throughput losses once the new ore came online.

Delivering measurable results at scale

A leading South American copper producer used the IES to evaluate the integration of HydroFloat™ coarse particle flotation. Embedded machine-learning models predicted potential recovery gains of 2 – 7% while enabling coarser grinding, reducing energy use and processing costs.

In another project, a mining technology company used the IES and ModelNet to simulate its rotary air concentration system. The modelling predicted recovery of an additional 5000 oz of gold from material previously classified as waste, while lowering downstream processing volumes.

This project demonstrates how the IES can deliver value at multiple scales – from optimising existing plants to accelerating the adoption of breakthrough processing technologies.

Integration, sustainability, and the future of the IES There is a noticeable increase in software adoption, globally. IES differentiators have played an important

role in leveraging value for different types of users within the mining and minerals processing industry, along with original equipment manufacturers (OEM) and consulting companies. The value that the IES provides its users varies – from reducing uncertainty in major investment projects through to supporting the identification of opportunity for operational and equipment design.

The need to assess new technologies and quantify their performance, investigate process efficiencies, and understand financial impacts has become a prominent driver in the discovery of the IES. The IES is designed to integrate with mine planning tools, fleet management systems, and plant control platforms, creating a digital twin that mirrors the operation’s current state. This allows sites to test potential changes in near real-time and understand the full value chain implications before implementation.

Corporate users can apply the IES across multiple sites for standardised analysis and sharing of best practices, while OEM partners can test equipment performance in varied operating contexts without the cost or risk of physical trials.

The platform also supports ESG objectives, with the ability to model water and energy use per tonne, forecast carbon footprint impacts, and test alternative flowsheets or operational strategies to reduce environmental risk. Recent projects have demonstrated how the IES can help quantify and optimise sustainability metrics alongside production outcomes.

Looking forward, Orica Digital Solutions is advancing the IES with expanded neural networking and machine learning capabilities, enabling models to capture and simulate processes such as flotation where data is often available. A major focus is the development of tailored front ends that allow specific tasks to directly access and apply elements of the IES workflow, bringing the platform into operational use rather than being confined to strategic planning. This evolution, described as a shift from proactive optimisation to proactive correction, aims to close the gap between strategic intent and operational execution, while also supporting multi-site optimisation and ESG-linked modelling for energy, water, and emissions.

Shaping the future of mine-to-mill

Figure 3. The IES can simulate breakage patterns to maximise throughput and energy efficiency.

32 november/december 2025 // global mining review

The mining industry’s challenges are complex and interconnected – and so are its opportunities. Digital platforms like the IES are turning mine-to-mill optimisation into a continuous, data-driven practice rather than a one-off exercise. By combining physics-based modelling, machine learning, and scalable cloud computing, the IES enables faster, more confident decisions that translate into measurable gains in recovery, productivity, and sustainability. As operations push to extract more value with fewer resources, such tools will play a central role in shaping the next generation of responsible, high-performance mining.

Mike Rikkola, Vice President, Software Defined Vehicle and Autonomy Platforms, Komatsu, USA, explains the importance of collaborations with Silicon Valley for mining companies and the industry in general.

34 November/December 2025 // global mining review

I

n September 2025, Komatsu announced a groundbreaking collaboration with Silicon Valley’s Applied Intuition, a company renowned for its expertise in vehicle intelligence and autonomy.

Why this is important

This collaboration represents the most significant technology investment in Komatsu’s more than 100-year history, signalling a bold commitment to revolutionising mining operations through a unified software-defined vehicle (SDV) and autonomy platform. The relationship aims to deliver transformative capabilities, enabling mining companies to operate more safely, efficiently, and sustainably in an era characterised by rising operational costs, labour shortages, and mounting decarbonisation pressures.

The digital transformation in mining

The mining sector is undergoing a profound digital transformation. Technologies such as the Internet of Things (IoT), cloud computing, and advanced analytics are being integrated into every aspect of mining operations. These technologies embrace real-time monitoring of equipment,

predictive maintenance, and data-driven decision-making – all of which contribute to improved safety, efficiency, and sustainability.

Regulatory and environmental pressures

Governments and regulatory bodies worldwide are imposing stricter environmental standards on mining operations. Companies are required to reduce emissions, minimise waste, and rehabilitate mining sites. The adoption of autonomous and software-defined vehicles helps companies meet these requirements by reducing fuel consumption, optimising routes, and enabling more precise control over operations.

Workforce evolution and skills development

As mining operations become more automated, the skills required of the workforce are evolving. There is a growing demand for workers with expertise in data analytics, robotics, and AI. Companies are investing in training and development programs to equip their employees with the skills needed to operate and maintain advanced technologies and improve the bottom-line.

global mining review // November/December 2025 35

Industry context: Why now?

The mining industry stands at a pivotal crossroads. By 2027, the global mining market is projected to reach US$2.78 trillion, yet the majority of mining trucks and equipment remain manually operated. Haulage and machinery-related incidents are leading causes of mining fatalities, and the sector is responsible for 4 – 7% of global greenhouse gas emissions, primarily due to diesel-powered vehicles. The convergence of rising costs, labour shortages, decarbonisation mandates, and surging demand for critical minerals has created a ‘perfect storm’ that demands urgent innovation.

Mining companies are under increasing pressure from regulators, investors, and local communities to modernise operations and reduce their environmental footprint. The shift toward digital transformation and automation is no longer optional – it is essential for survival and competitiveness. Companies that fail to adapt risk falling behind as the industry embraces new technologies that promise greater safety, efficiency, and sustainability.

Osama Oulabi, General Manager – Kingdom of Saudi Arabia & Middle East at Speedcast, addresses the increasing importance of AI and automation across MENA mining projects.

38 november/december 2025 // global mining review

M

ining operations continue to grow in both criticality and complexity across the world, but nowhere quite like the Middle East and North Africa (MENA). Having historically been focused primarily on oil and gas, the region’s mining sector is now undergoing a profound transformation, thanks to its generous deposits of copper, zinc, phosphate, and lithium – vital minerals for growing renewable energy technologies.

This transition has been underpinned by initiatives such as Saudi Arabia’s ‘2030 Vision’, which is intensifying the region’s focus on mining, positioning the sector as a strategic pillar of economic diversification as it looks to harvest its estimated US$2.5 trillion in untapped mineral reserves.

Sustainability is not the only focus for governments across MENA, however. In particular, the desire of Middle Eastern countries to be at the forefront of artificial intelligence (AI) developments has contributed to the introduction of new technologies. As a result, the mining strategies utilised in the region have undergone a massive shift in the last five years, with operators empowered to embrace greater automation.

However, these mining sites are located in some of the most desolate regions on Earth. Critical infrastructure is scarce in the vast deserts and

remote mountain ranges that boast these huge mineral deposits. Operational success now hinges on a less visible but critical enabler: connectivity.

Overcoming geographical challenges

The Middle East’s rugged terrain is ideal for mining. The vast Arabian Desert, especially the western Arabian Shield, holds a wealth of mineral deposits and rare earth elements. Countries like Oman are also abundant in large-scale copper deposits, while in Africa, Morocco boasts huge stores of phosphates, fluorine, and barite. However, the lack of critical infrastructure in and around these deposits presents an obstacle.

Reaching these sites with water, ventilation systems, and communication networks is very challenging due to geographic, climatic, and logistical factors. The desert interiors of countries situated within the region are underdeveloped, lacking main roads and legacy rail routes. In addition, extreme heat and sandstorms make new infrastructure incredibly difficult to build, especially since construction materials and heavy equipment must be transported long distances over unpaved and rugged roads. This is further compounded by seasonal flooding in river valleys – known as wadis – disrupting ground access, even for well-prepared operations.

Saudi Arabia’s most remote mining location took well over six years of intricate planning before it was up and running. In a well-orchestrated effort to capitalise on the region’s 180 million t of Bauxite, the Al Ba’itha mine was completed in 2014 after a US$169 million contract covered the development, constructing a 13.5 m-wide haul road and a 1400 km rail line. This site works effectively because it is supported by self-contained operational facilities, such as on-site power and water systems, which are critical for prioritising worker safety.

Even then, its remoteness led to health and safety issues, with Buradyah – the closest city with a major hospital – approximately 196 km away, which is a distance too far and long to trek, should a life-threatening incident occur.

global mining review // november/december 2025 39

The technological transition

Thankfully, recent technological advancements mean human exposure to dangerous conditions is now being kept to a minimum. Instead, the onus is on machinery to carry out the main bulk of mining work, such as drilling and blasting, ore processing, and material extraction. This shift is underpinned by automation – forming the backbone of the machinery’s daily operations.

Take trucks and loaders, for example. Autonomous haulage systems (AHS) are now enabling mining trucks and loaders to operate without human drivers. Through a combination of GPS, LiDAR, AI, radar, and onboard sensors, vehicles can navigate mine sites using pre-mapped routes, eliminating operators from dangerous environments like pit walls and high-dust zones. AHS usage often follows drone usage to help survey and map these large routes, reducing the need for on-ground inspection.

Worker safety is prioritised as a result, while efficiency and workloads are increased through minimal vehicle downtime, allowing remote workers to process data 24 hours a day, seven days a week.

These real-time analytics are providing immediate insights on operations to allow for proactive decision-making. All site activities are evaluated for performance and anomalies, optimising resource utilisation and improving overall efficiency.

For instance, in AHS, real-time analytics provide predictive maintenance to help monitor truck tyre pressure, engine temperature, and load distribution – preventing mechanical failures and maintenance costs by up to 30%.

The data can also be used in ensuring environmental, social, and governance (ESG) compliance. Driven by international frameworks like the Global Reporting Initiative, which introduced a sector standard for mining last year, analytics and sensors are paired to monitor key metrics such as emissions, dust, and water usage. AI-integrated air quality monitoring stations track particular matter and airborne contaminants using predictive maintenance, and onboard sensors monitor both groundwater levels and emissions, ensuring compliance and audit readiness.

Enabling reliable connectivity

It is fair to say that the use of AI and automation within mining operations is increasing efficiency, ensuring workplace safety, and adhering to ESG regulations. Yet, in the past, the absence of reliable connectivity would have made the aforementioned tools too difficult to scale. Now, mining operations in the Middle East are supported by a new generation of advanced connectivity solutions, all designed specifically for remote, data-intensive environments in mind.

At the core of these technologies sits satellite connectivity. It is crucial for enabling various key applications including autonomous vehicles and data transfers used for real-time analytics. As such, operators have grown increasingly reliant on technologies such as multi-orbit satellite constellations – systems that utilise satellites in multiple orbital altitudes.

This includes geostationary (GEO) satellites, which offer broader coverage to better suit applications that require consistent, wide-area connectivity for general internet access and reliable data transfer. Alternatively, low Earth orbit (LEO) satellites can be deployed to better suit real-time applications like data analytics. Operators are also utilising medium Earth

40 november/december 2025 // global mining review

orbit (MEO) satellites, which merge both types to offer a strong balance of coverage and latency.

Very small aperture terminals (VSAT) also provide the means for rapid voice, data, and internet connectivity. Numerous, ‘always-on’ VSAT systems can be deployed across construction and operational life to deliver constant and consistent connectivity to these remote locations. LTE/5G networks can even be deployed, depending on the circumstances. These are often hybrid systems that can switch between satellite and terrestrial to maintain uptime where available. Regardless of the connectivity method, these solutions all facilitate the optimal use of IoT devices in order to bring enhanced safety, improved efficiency, and cost savings to mining operations.

Additional resiliency can be achieved through L-band LEO connectivity. Sites across MENA often encounter challenging weather conditions and physical obstructions, especially on oil rigs and supply vessels. The L-band constellation is used within the region to provide reliable broadband and midband voice and data capabilities essential for IoT solutions and sensor and safety services. This means operators benefit from uninterrupted communication, even in demanding environments.

However, we are now seeing companies such as Speedcast take these offerings one step further. Additional network optimisation tools are bolstering another layer of real-time connectivity, with solutions such as software-defined wide area network (SD-WAN) being plugged into satellite and LTE/5G base stations to enable greater precision when routing data.

SD-WAN works by building upon software-defined networking (SDN) to connect various services to different locations, whether that be control rooms or direct to autonomous vehicles. Traffic to and from these systems can be managed and routed based on predefined policies, network conditions, and application requirements.

With connectivity and IoT comes the inherent risk of cyberattacks. While the Middle East has not yet been targeted, other plants, such as Evolution Mining in Australia, have fallen victim to cyberattacks aimed at IT systems, causing extensive downtime at each site. Networks must now be fault tolerant as well, which is why SD-WAN, as well as other edge computing systems, now cover security risks through built-in intrusion detection systems and firewalls. Doing so adequately protects the network from cyber threats. Even if a primary connection fails for whatever reason, diverse paths and failover mechanisms will also ensure uninterrupted services are maintained.

Looking to the future

The advanced connectivity solutions used to support mining sites across MENA continue to underpin the use of automation and AI in operations. The same advanced systems and solutions are also being integrated in mining sites from Siberia to South America, ensuring that the raw natural resources can be extracted in a safe and efficient manner, no matter the terrain.

As AI technologies continue to innovate and advance, so too will these connectivity solutions. Operations will continue to scale, and pairing advanced connectivity with secure optimisation tools such as SD-WAN will help lay the groundwork for the integration of new technologies like augmented reality (AR), ushering in a new era of innovative, worker-prioritised mining. For mining sites, the future is now.

Ben Lawrence, Gecko Robotics, USA, evaluates the optimisation of infrastructure health in mining, and considers the importance of speed, smarter CAPEX, and identifying the root cause when tackling issues.

M

ining has always been seen as an industry of extremes: enormous machines, remote sites, and non-stop pressure to move material faster and cheaper.

But as those in the industry know too well, there is a quieter reality shaping outcomes just as much as ore grades or commodity prices – the health of the infrastructure itself.

For years, the industry has accepted inspection and maintenance as a necessary headache – slow, costly, dangerous, and often based on incomplete information. The default approach has been to patch things up, replace assets early, and carry the costs as part of doing business. But that equation is breaking down.

Aging infrastructure, tighter margins, and higher safety and ESG expectations mean the old playbook is no longer good enough.

A new way of thinking is emerging, powered by robotics, AI, and advanced data science. It is not just a shiny technology story. It is about unlocking three clear sources of value that are already changing the way mines operate: faster and safer inspections, smarter use of capital, and the ability to finally get to the root cause of infrastructure failures.

And there is a crucial ingredient running through all of it: value tracking. Mining companies do not have room for science experiments or nice-to-have pilots. They need measurable impact from day one, with the ability to hold their technology partners accountable for results.

global mining review // november/december 2025 41

The 3 S’s: Speed, scaffolding, and safety

If you ask any veteran miner what is wrong with traditional inspections, you will likely hear some version of the following: they take forever, they put people in harm’s way, and the results are still incomplete.

This is the case because for as long as mines have existed, infrastructure inspections have been carried out the same way: people with clipboards and handheld sensors, often dangling from scaffolding or ropes, trying to take consistent readings in difficult conditions. Think of ‘Joe on a rope,’ inching along a tank wall, taking single ultrasonic thickness readings every few feet.

This approach has three major flaws: It is slow. Large assets can take weeks or even months to inspect manually, often requiring downtime or scaffolding builds that themselves add cost and delay.

It is dangerous. Inspectors work at height, in confined spaces, and around operating equipment. Every inspection carries risk.

It is incomplete. A few hundred readings on a tank wall or pipeline section cannot capture the full picture of structural health.

Robotics change that equation completely. Robotic platforms equipped with advanced sensors –

Figure 1. Gecko’s Toka 5 robot collecting data at a mining facility.

i.e. ultrasonic phased arrays, LiDAR, electromagnetic acoustic transducers, and thermal imaging – can scan every square inch of an asset, often while it remains in service. Instead of hundreds of readings, operators get millions. Instead of weeks, they get results in days or hours. And instead of exposing people to risk, robots do the dangerous work while inspectors oversee from a safe distance.

The impact is immediate: fewer scaffolds built, faster turnaround, safer teams, and dramatically better data. These are not soft benefits. They translate directly into hard cost savings and stronger decision-making. In an industry where downtime is measured in millions of dollars per day, that speed and safety dividend alone make robotics a compelling investment.

Smarter CAPEX: Stopping the 20 – 30% waste

If speed and safety are the quick wins, smarter CAPEX is where things get transformational. Mining companies today are routinely wasting between 20 – 30% of their capital expenditure on projects that do not deliver the intended return. Why? Because they lack accurate, high-resolution data on infrastructure health.

The traditional approach forces planners into guesswork.

Without confidence in the true condition of equipment, they default to conservative assumptions. That means replacing assets earlier than necessary ‘just in case’, over-engineering solutions, or spreading dollars too thin across projects that do not address real risk. The result is misallocated capital; billions of dollars globally every year.

With robotic inspection and AI analysis, the picture changes completely. Planners can see, down to the square inch, where degradation is occurring, how fast it is spreading, and how long assets can safely remain in service. Instead of blanket replacements, they can prioritise only the sections that need rehabilitation. Instead of defaulting to worst-case scenarios, they can forecast remaining useful life with confidence.

Consider a flotation tank: manually inspected, it might be flagged for full replacement at a cost of tens of millions.

Robotic data, however, may reveal that only 20% of the structure is nearing end-of-life, while the rest has years of safe service left. Suddenly, instead of a US$20 million project, the mine faces a US$5 million targeted rehabilitation, with the same risk reduction and a fraction of the spend.

Multiply that across conveyors, pipelines, crushers, and boilers, and the savings are staggering. More importantly, those dollars are not just saved but they can be redirected toward growth, ESG initiatives, or other critical projects.

Smarter CAPEX is not just about spending less. It is about spending right. And in an industry where capital efficiency is increasingly scrutinised, that is a competitive advantage that shows up on the balance sheet.

Root cause analysis: Beyond symptoms to solutions Figure 2. Gecko’s Cantilever platform showing the health of an asset.

42 november/december 2025 // global mining review

Perhaps the most exciting frontier is root cause analysis. For the first time, mining companies are no longer treating infrastructure data in isolation. Instead, they are layering it with rotating equipment data and process data to

understand why damage is occurring in the first place. This is a shift from symptom-chasing to problem-solving.

Take a pipeline suffering accelerated corrosion. Traditional inspections might be lucky enough to identify thinning walls and trigger a repair or replacement. But with root cause analysis, operators can cross-reference the damage with process data, say a chemical imbalance in the slurry or vibration patterns in upstream pumps. The insight is not just where corrosion is happening, but why.

That opens the door to new, data-backed standard operating procedures. Instead of relying on tribal knowledge (“we’ve always run it this way”), mines establish evidence-based practices that prevent damage before it occurs. Speed limits can be set, chemical balances adjusted, operating cycles optimised, all guided by data, not guesswork.

This has three powerful effects: It extends asset life. By addressing the root cause, operators slow or even stop the mechanisms driving degradation.

It elevates performance. Mines move from reactive fixes to proactive optimisation, running assets closer to their true potential.

It builds institutional knowledge. Instead of relying on individuals with decades of tacit experience, mines codify best practices into digital SOPs that scale across the organisation.

For an industry grappling with a talent shortage, this last point is crucial. Root cause analysis creates a knowledge base that outlives retirements and turnover, ensuring that operational wisdom is not lost but continually built upon.

Value tracking: The crucial ingredient

Of course, the most important thing is that this translates into real results. Mining leaders do not have time or budget for science experiments. They need to know that every inspection, every model, and every dollar spent delivers measurable value.

That is where value tracking comes in. By establishing clear baselines and KPIs upfront – whether it is reduced downtime, CAPEX avoidance, safety improvements, or throughput gains – mines can hold technology partners accountable.

This accountability is essential. It ensures robotics and AI deployments are not just exciting pilots that fizzle out, but rather they become embedded, trusted parts of the operation. When value is tracked transparently, successes build momentum, skeptics become champions, and the technology scales from one site to an entire portfolio.

The human dimension: Augmenting, not replacing

There is another misconception worth addressing: that robotics and AI will displace human workers. The reality on the ground is very different. These technologies are not about replacing people, they are about augmenting them.

Robots handle the tedious, dangerous, or physically impossible tasks: climbing tank walls, crawling inside confined pipelines, scanning thousands of square meters without fatigue. Humans interpret, decide, and act on the insights.

This shift frees skilled workers to focus on higher-value problem solving rather than repetitive, risky labour. One of Gecko’s clients recently said: “It turns my skilled tradesmen from problem finders to problem solvers, and that is a 10x more valuable exercise. It also makes the industry more attractive to new talent. Just as defense and aerospace have drawn young engineers and data scientists with cutting-edge technology, mining now has the opportunity to do the same.

By embracing robotics and AI, the industry positions itself not as a legacy sector, but as a frontier for innovation.”

The bottom line: A new era of mining maintenance

Figure 3. Gecko’s Toka 5 robot and Cantilever platform.

Figure 4. ‘Joe on a rope’ manually assessing health.

44 november/december 2025 // global mining review

The story of mining has always been about extracting value from the earth. But now, a new chapter is being written. One where value is also extracted from infrastructure data.

By embracing speed, smarter CAPEX, and root cause analysis, the industry is moving beyond outdated inspection methods and guesswork-based planning. It is creating a world where assets are safer, capital is better spent, and operations run closer to their true potential.

And, by embedding value tracking throughout, mining leaders can be confident that these innovations deliver, not someday, but from day one.

Those who move first will save millions, extend asset life, and operate more safely. Those who hesitate will spend more, risk more, and fall further behind.

The playbook is clear. The tools are here. The question for mining leaders is simple: are you ready to turn infrastructure into your next source of competitive advantage?

Hernan Muniz, Weir, Australia, explores how the mining industry can effectively combine new technology and data insights with domain expertise to maximise the potential of mining solutions.

Figure 1. Data insights from connected assets help predict maintenance needs before they impact production.

n recent years, the mining industry has increasingly embraced digital technologies. Yet, while these tools are essential, they do not create value on their own. The real advantage lies in data-driven services, the ability to turn raw data into actionable insights that drive performance, reduce downtime, and unlock new efficiencies.

The digital shift

Weir has undergone a digital transformation focused on enhancing customer operations through delivering NEXT intelligent solutions and services. As the world’s leading slurry pump supplier, Weir’s digital journey began with NEXT condition and performance monitoring for its WARMAN® slurry pumps.

global mining review // November/December 2025 45

These solutions use sensors to track vibration, temperature, and speed, detecting early anomalies before they escalate. It also includes insights on where the pump is operating on the pump curve as well as AI algorithms – not only to detect those early anomalies – but to also predict the wear of different components.

But the real power comes from combining this data with deep domain expertise. Weir’s teams, involved in every stage of the pump lifecycle, from design to maintenance, use proprietary datasets to deliver insights that help operators optimise performance. For example, Weir can detect impeller wear and recommend process adjustments to ensure all components reach the next scheduled maintenance window.

These insights can also be automated, enabling proactive, data-informed decision-making.

Extending intelligence across the circuit

Weir’s digital capabilities now span a broader portfolio, including CAVEX® hydrocyclones. A prime example is its NEXT

roping index solution, which tackles a persistent challenge in mineral processing: balancing cyclone efficiency with operational stability.

Historically, operators have run cyclones conservatively to avoid roping – a condition that disrupts separation and harms downstream processes. This cautious approach often sacrifices throughput and separation efficiency.

Weir’s solution changes that. By integrating real-time sensors and advanced analytics, the NEXT intelligent solution for cyclones continuously monitors cyclone conditions, enabling operators to confidently run in a semi-roping state, close to peak capacity without crossing into detrimental territory. This unlocks: Increased throughput and grinding efficiency.

Reduced energy waste from overgrinding.

Improved particle size distribution (PSD) for better flotation recovery.

And the technology does not stop there. Weir’s digital capabilities extend across a wide range of equipment and process areas. For example: Spools and hoses are monitored for wear percentage, helping prevent unexpected failures.

Screens are equipped with vibration and temperature sensors to assess asset condition and reduce unplanned downtime.

High pressure grinding rolls (HPGRs) can be remotely monitored, with Weir’s solutions integrating directly with local machine PLCs for real-time visibility.

Beyond individual assets, Weir’s NEXT process optimisation solution provides holistic oversight of entire process areas, such as the mill circuit, integrating data from multiple assets to not only assess equipment health, but also optimise operational performance.

These innovations reflect Weir’s commitment to building connected, intelligent systems that go beyond monitoring; they actively support decision-making and continuous improvement across the entire mineral processing value chain.

Figure 2. Collaborating through data-driven tools to improve equipment reliability and process efficiency.

Tailored services for every stage of the digital journey Mining operations vary widely in their digital maturity. Some have in-house teams and established systems; others are just beginning to explore digital opportunities. That is why a one-size-fits-all approach does not work.

Weir’s NEXT intelligent solutions offer two tiers of service: Self-serve: Customers access data and analytics via a digital platform, enabling independent analysis and decision-making.

Supported service: Adds expert oversight, remote monitoring, and proactive recommendations to help customers maximise performance and minimise downtime.

Figure 3. Centralised monitoring brings together equipment, process, and performance data to support integrated operations.

46 November/December 2025 // global mining review

With over 100 connected sites and more than 500 assets monitored, Weir has already identified over 600 anomalies, preventing unplanned downtime and improving operational efficiency.

To support this, Weir has expanded its teams to include data scientists, analysts, and specialists in vibration analysis, reliability, and process, combining equipment expertise with digital intelligence.

As part of the ongoing commitment to enhance its digital offering, Weir has also partnered with Viking Analytics, a Swedish company specialising in AI-powered vibration analysis and condition monitoring.

Viking’s advanced machine learning technology, capable of detecting early signs of equipment failure without the need for labelled data or manual thresholds, will be exclusively integrated into the NEXT intelligent solutions.

This collaboration strengthens Weir’s predictive maintenance capabilities, helping customers maximise uptime and streamline maintenance through smarter, data-driven diagnostics.

Building a collaborative ecosystem

The mining industry is undergoing a cultural shift in how it approaches collaboration. As the benefits of digitalisation become clearer, companies are investing in IS&T systems, protocols, and infrastructure to enable secure data integration.

This shift is supported by shared platform partners like AVEVA and XMPro, which streamline integration and accelerate innovation. The result is a more connected ecosystem where miners and solution providers can collaborate more effectively.

Investing in upstream innovation

Historically, mining operations have operated in silos, with limited visibility between mine and plant. For example, metallurgists often lack real-time insights into the material entering the processing plant, limiting their ability to optimise performance.

Weir is addressing this by investing in upstream digital technologies, including the acquisitions of Micromine and Motion Metrics. These solutions provide greater visibility into ore characteristics and mine conditions, enabling better planning and more responsive processing strategies.

The future of mining services

The future of mining lies in intelligent, performance-focused ecosystems. These ecosystems will integrate digital platforms, automation, and advanced analytics to deliver continuous improvement and measurable outcomes.

By combining real-time monitoring, predictive capabilities, and domain expertise, mining companies and OEMs can co-create value in ways that were previously unattainable.

The result is a more agile, efficient, and sustainable mining industry, powered by data and driven by services.

Mining’s digital transformation is not just about technology, it is about how solution providers use that technology to deliver value. Weir believes that the future belongs to those who can turn data into decisions, and decisions into results. Through its NEXT intelligent solutions and expert services, Weir is helping miners unlock the full potential of their operations.

Figure 1. Air cannons use a plant’s compressed air system to deliver powerful and timed blasts that efficiently dislodge early buildups.

Brad Pronschinske, Martin Engineering, USA, highlights the importance of understanding material flow in silos and hoppers, and how blockages and buildups can be prevented.

W

hatever is being mined, and however it is being processed it, there are locations throughout plants where materials need to be held up or stored before being channelled into the next stage of production. However well designed they may be, vessels

such as silos, hoppers, bins, and chutes can be affected by the problems of materials clinging to the inside walls.

Once material starts to stick, the buildup is generally fast and dense, slowing the flow, causing spillages and secondary blockages, and ultimately resulting in

global mining review // november/december 2025 49

unscheduled downtime. Compounding these issues, the temptation to find a quick way to shift a blockage, often without the proper risk assessment, safe access, or the correct tools or training, can lead to workers putting themselves at risk.

This is where flow aids come in, innovative devices specifically engineered and installed to promote material flow, clear buildups, and prevent clogging – avoiding costly downtime and reducing the associated safety risks. A variety of flow aid technologies are available, but to know what will work best for a specific application, the first step is understanding how, where, when, and why clogs are happening in a particular vessel. The next step is redesigning the system not only to clear blockages but also to eliminate the need for any worker involvement in doing so, using the right flow aids.

Capacities, characteristics, and clogging

Understanding the function and maximum load of each vessel in the process is vital, as is an appreciation of the physical properties of the materials passing through, including moisture content and temperature, plus the effect of atmospheric conditions. Wide variations in the size and shape of particles also affect the flow characteristics. Failure to consider these basic factors can lead to the installation of suboptimal designs that increase the likelihood of buildups and blockages.

Figure 1. The discharge point generally matches the geometry of the vessel.

Figure 2. Martin Engineering first launched the air cannon 50 years ago and has continually innovated through the application of the latest technological advances.

50 november/december 2025 // global mining review

Further, if a hopper is not designed to carry the required material load at full capacity, a sudden surge of material or a clog can rapidly lead to harm. And even if a hopper or silo is engineered properly, repeated impact and abrasion from loading over years can cause the vessel walls to distort or wear thin, decreasing their ability to perform as designed, compromising structural integrity, and increasing the risk of a serious event.

There are numerous reference guides that explain vessel loading in order to determine the right design, covering load factors such as: Dead load – The total weight of the structure, including attached components and equipment supported by the structure.

Live load – Forces exerted from the stored material, including high and low pressures caused by flow, plus anything independent of the structure such as snow, positive and negative air pressure, wind or seismic load, and any forces from materials stored against the external wall.

Thermal load – Caused by temperature differences between the inside and outside faces of the wall.

Settling load – Forces from uneven settling and movement of the structure.

Clearly, the combined factors that play a part in buildups, blockages, and overloading can be complex – the weight, size, and type of material; the load velocity, direction, and distribution; the design of the vessel; its age and condition; atmospheric conditions; and the monitoring and maintenance regime. Once a major buildup has occurred, the moment the clogged material is released, the force of the surge has been known to overwhelm and damage the structure, the discharge gate, or the skip or conveyor onto which it is flowing. So before releasing a blockage, understanding the weight of the material in the clog itself is important too.

Hopper geometries and discharge points

Discharge points come in varying shapes, depending on the vessel and the material flow characteristics (Figure 2). Plant manufacturers carefully choose discharge point shapes based on a series of load and flow factors. Spouts that are narrow, such as those found on conical or pyramidal shapes, direct flow in a vertical column either into a chute or specific loading area. Slotted spouts, like those found on the wedge or transition shapes, typically distribute material in a narrowly defined line for loading onto conveyors or into containers such as trains or trucks.

In all cases, the shape of a vessel should match that of the discharge point or it will be prone to clogging. The slope angles in discharge point geometries can also contribute to clogging, depending on material characteristics, the specifications of the application, or the placement of the vessel.

Discharge points often feature gates (to halt material flow for incremental filling of skips, rail cars, or trucks) and grates (to break up smaller agglomerations or to slow the flow of material when loading onto a conveyor). Either way,

sooner or later operators find that these devices can exacerbate clogging by stopping or slowing material at the structural choke point of the vessel.

Unblocking and unsafe practices

Once a clog has been detected, many operators witness unsafe practices that, at the time, may seem like a simple and harmless solution, but frequently cause injuries and are even known to cause fatalities.

The most common starting point is beating the vessel walls with mallets or other heavy objects to loosen stuck material. Besides the safety risks of manual handling, over time, the more the walls are pounded, the worse the situation becomes, as the bumps and ridges left in the wall from the hammer strikes will form ledges that provide a place for additional material accumulations to start.

Another hazardous yet popular practice is poking or lancing from underneath the clog at the discharge point.

This can result in a sudden surge of falling material, burying or crushing the worker(s) below. Physical lancing from above is also common, often with makeshift platforms that allow easy access but provide little protection should a worker slip and fall into the vessel.

Manually air lancing the blockage from the mouth of the vessel at the top can be an effective option, but only when guardrails are fitted, or a safe access platform is used. Of course, the reach of the lance and the pressurised air stream must match the size of the vessel and the clog. And again, unless a harness is worn, workers could still fall in trying to

get the lance down to the clog, even if guardrails are present.

Perhaps the most prevalent cause of worker injuries is entry into the vessel. Along with potentially sinking into the material, especially in the centre, the silo or hopper contents could be ‘bridging’ and suddenly release. If a worker enters the vessel and stands on the fragile bridge or on a buildup to the side, a sudden discharge could pull the worker into the cavity, causing a serious fall or engulfment.

These unsafe situations and behaviours can be avoided by introducing flow aids to the vessel to mitigate clogs, promote material flow, and reduce downtime.

Productivity through prevention

As the term implies, flow aids are components or systems installed to promote the flow of materials through a silo, bin, hopper, or chute whilst controlling buildups, overflows, and spillage. Flow aids come in a variety of forms, including rotary and linear vibrators, high and low-pressure air cannons and aeration devices, as well as low-friction linings and optimal chute designs, to encourage the most efficient flow of bulk materials.

Such solutions can be combined in any number of configurations to complement one another in an integrated system to eliminate clogging and improve overall productivity. Flow aid devices are effective in virtually any bulk material or environment, including heavy duty applications, hazardous materials, and extreme temperatures.

When employing flow aids, it is critical that the hopper or silo structure is sound and the flow aid device(s) are properly sized and mounted, because their operation can exert additional stresses on the structure. A well designed and maintained vessel will not be damaged by the addition of correctly sized and mounted flow aids.

It is also important that any flow aid device is used only when discharge gates are open and material can flow as intended. Best practice is to use flow aids as a preventive solution to be controlled by timers or sensors to avoid material buildup, rather than waiting until material accumulates and begins to restrict the flow. Using flow aid devices in a preventive manner not only reduces the chance of clogging, but also enhances safety and can even save energy.

Start with engineered vibration

A better alternative to pounding the outside walls of a hopper or chute is the use of engineered vibration, which supplies energy precisely where needed to reduce friction and break up potential accumulation. This enables material to keep moving to the discharge opening without damaging the chute or vessel. The technology is often found on conveyor loading and discharge chutes, but can be

Figure 3. Rotary vibrators supply energy best suited to keeping fine, dry materials moving.

effectively applied to other process and storage vessels, including silos, bins, hoppers, screens, rail cars, feeders, cyclones, and heat exchangers.

Productivity with a blast

Where vibrators alone may not achieve optimal flow, a highly effective solution for eliminating material accumulation in chutes and vessels is the use of low-pressure air cannons, pioneered and patented by Martin Engineering in the 1970s. Air cannons, or blasters, use a plant’s compressed air system to deliver powerful and carefully timed blasts to dislodge buildups before they become problematic. Air cannons can be mounted on metal, concrete, or even wooden surfaces as long as they are structurally sound. The basic components include an air tank, a fast-acting valve with a trigger mechanism, and a nozzle to distribute the air in the desired pattern to clear the accumulation most effectively.

The sudden blast of air released by the valve on an air cannon is directed through a specially designed nozzle, which is strategically positioned in the chute, tower, duct, cyclone, or other location. Often installed in an array of several air cannons and precisely sequenced for maximum effect, the devices can be timed to best suit individual process conditions or material characteristics. These air blasts help to break down material accumulations ensuring normal flow is maintained. In order to customise the air cannon installation to the service environment, specific air blast characteristics can be achieved by manipulating the operating pressure, tank volume, valve design, and nozzle shape.

In the past, when material accumulation problems became a recurring issue in hard-to-access enclosed vessels, operators would have to either limp along until the next scheduled shutdown or, more likely, endure expensive unplanned downtime to lance the clogged buildups. Such is the importance of keeping materials flowing that many vessels now feature mountings so that devices – such as air cannons and vibrators – can be fitted safely with relative ease. The question is not about whether to fit flow aids, it is more about what type, how many, and where.

Conclusion – Think clean

Given the demands and complexities of processing mined materials, buildups and blockages in silos, hoppers, and other vessels should be banished with engineered flow aids.

The key to success lies in selecting the appropriate flow aid technology based on material properties, vessel design, and operating conditions. Moreover, proactive and preventive use of these solutions, rather than reactive measures, is proven to help maintain optimal performance and can even extend the lifespan of storage and transfer equipment.

As mining plants increasingly prioritise production efficiency and worker safety, investing in well-designed flow aid systems has become a necessity. By embracing such innovations, producers can achieve smoother operations, maximise throughput, and create a safer working environment, ensuring that materials move through the process without unnecessary interruptions.

T

Ling Schneider, Product Manager, XRF, Thermo Fisher Scientific, outlines how XRF technology is driving precision and efficiency in mining.

he global demand for minerals is rapidly growing, driven by the need for raw materials that support global advancements in renewable energy, digitalisation, and infrastructure. The mining industry plays a critical role in supplying these essential materials, such as lithium, cobalt, and copper, but meeting demand is not just about delivering more. Mining companies need to maximise resources and optimise operations, while also prioritising safer,

cleaner working environments. They need advanced analytical technologies that can ensure that operations are running efficiently, safely, and profitably.

X-ray fluorescence (XRF) technology delivers quick, precise analysis data so that teams can make informed decisions at every stage – from collecting the first ore samples to manufacturing the final product. Because of the explorative nature of mining work, miners are often challenged by determining ore

grades or elemental composition in physically demanding environments. When working at a site that is remote, rugged, and unpredictable, success depends on having the right data when it is needed. Many modern miners depend on XRF technology to help them work smarter, safer, and more efficiently.

The benefits of XRF technology for the mining industry

From mineral exploration to processing to analysis, XRF has become a crucial tool for mining operators and mineral processors. While its ability to give fast, precise elemental data sets it apart, companies can reap the long-term benefits of maximised resource recovery, enhanced operational efficiency, and reduced environmental impact when they adopt this innovative technology.

Accelerated time to data is one of XRF’s biggest strengths. It allows miners to identify high-value zones, separate ore from waste, and adjust processes to maximise the return from each load. When teams have access to real time data throughout the workflow, they can make informed decisions for grade control that help cut waste and boost yield.

During exploration, XRF helps miners map out elemental patterns and enable quick sampling to identify the best target for drilling. In both opencast and

underground mines, handheld XRF analysers let crews conduct rapid, non-destructive elemental analysis onsite. This significantly speeds up the process of prospecting and exploration, as it limits the need to send samples to offsite labs and wait for results. These portable devices enable quick and informed decision-making and contribute to optimising mining operations.

Some samples may need to be sent to a mine-site lab for detailed analysis. These labs require high precision elemental analysis for a variety of applications – especially when there is a need to acquire data on many elements at once. The ARL X900 XRF spectrometer with integrated X-ray Diffraction (XRD) capabilities can give analysts both elemental and mineral phase data to support process control and quality checks. This technology can help mining labs solve a wide range of analytical challenges with reliable data.

According to a recent Ernst & Young report, environmental stewardship has become a key priority for the mining industry, and XRF also plays a big role in environmental monitoring.1 It supports tailings management, dust monitoring, and emissions monitoring, which help mines stay within safe limits and comply with regulations.

Mining companies, mineral processing plants, and geological survey organisations can consistently extract high quality compositional data from their samples – every time. Environmental monitoring agencies and regulatory bodies can also benefit from using XRF technology, as it provides accurate and continuous data on emissions and pollutants for reliable reporting. The technology’s flexibility means that it can be used to support everything from resource estimates to closure and rehabilitation.

Solving the industry’s toughest problems

Mining is a demanding practice and industry. Many mines operate in harsh environments – either in remote locations, at high altitudes, or in places with severe weather patterns. XRF is built to meet these real-world demands. For example, benchtop energy dispersive XRF (EDXRF) spectrometers are often used for mining nickel ores. These instruments are small, transportable, and only require electricity so there is no need for a gas line, vacuum pump, or strong electricity supply. This makes them ideal for fieldwork where resources are limited.

Sample preparation is another common challenge for miners, and poor sample preparation can distort data and result in an inaccurate assessment of ore quality or elemental analysis. Many legacy techniques, such as atomic absorption (AA) or Inductively Coupled Plasma (ICP) require samples in liquid form. Some materials can be difficult to digest for AA and ICP analysis, but XRF makes solid and liquid analysis easier. With XRF, solid sample preparation is straightforward, using either pressed pellets for minor or trace elements or fused beads for major elements. For liquids or pasty semi-liquid samples, such as lithium from salt lakes,

XRF can analyse them directly, guiding plant operations and process control. The technology requires far less sample preparation than other techniques and can help save time and reduce errors throughout the process.

When demand heats up, mines need to process more samples, faster. Many XRF solutions have ready-to-use calibrations for common materials, such as steel, cement, or iron ores, so teams can get immediate results from day one. For demanding industrial environments, XRF analysers with a dual sample loader enable high throughput without losing time from sample pumping, and simultaneous wavelength dispersive XRF (WDXRF) uses fixed channels for each element, delivering fast analysis and high throughput.

With the ability to quickly acquire precise elemental analysis at any site, mining companies can make better decisions at every turn.

Optimising mining for a cleaner, faster path forward

The latest XRF instruments are enabling the mining industry to operate smarter and more sustainably.

Next-generation spectrometers with advanced detectors offer increased resolution, with detection limits less than one part per million (ppm) for heavy elements and 10 – 100 ppm for light elements, and even faster time to results.

Automated features, such as for sample preparation, reduces manual work for miners and results in

fewer errors. Modern XRF analysers can also now easily connect with lab software and plant controls, making it even easier to track results and share data across teams.

Investing in XRF empowers mining teams to make fast, informed decisions so that they can recover more valuable materials, cut waste, and lower their impact on the environment. However, to ensure that their XRF equipment always performs at its best, mining companies should collaborate with technology providers for installation, training, calibration, or maintenance services. With expert support at their fingertips, mining companies can use XRF to meet today’s challenges and prepare for tomorrow’s opportunities.

The technology is keeping pace with the industry’s needs – empowering mining teams with better sensitivity, faster results, and easy digital integration.

From user friendly, point-and-shoot handheld analysers to automated solutions for fully unattended use, XRF technology holds the key for modernising and sustaining mining operations. As the world’s need for minerals grows, the mines that succeed will be those that work smarter, powered by innovative technologies like XRF.

Kelly Baker, Xylem Dewatering Solutions, USA, describes how designing the right slurry pump system is key for mining success.

Figure 1. Tailings management ponds at mining sites depend on reliable, efficient slurry pump systems. The systems transport abrasive and high-density slurries, which are a mixture of liquids and solid particles – such as ore, tailings, and other mining residues – from the ponds to designated storage facilities or to the next process.

R

egulatory approvals are complete, financing is secured, the infrastructure has been built, and crews are ready to go. Suppliers realise that mining companies are under tremendous pressure to get new mining sites up and running as soon as possible. Detailed planning processes for building custom equipment can frustrate miners when they just want to install slurry pumps and get to work.

In tailings management systems, slurry pumps are critical for transporting abrasive and high-density slurries, which are a mixture of liquids and solid particles, such as ore, tailings, and other mining residues. The pumps move mining operations waste to designated storage facilities or to the next process. Efficient slurry systems minimise operating costs and maximise profitability.

The devil is in the details

Unfortunately, skipping critical steps in slurry system planning can cause major operational headaches. Clogging, reduced flow rates, and damaged equipment are all

avoidable risks that can derail a site’s productivity if time is not spent gathering accurate site data at the beginning of the planning process.

To design an optimal system, an experienced supply partner will want to know: � Flow rate requirements: Typically measured in gallons per minute (GPM) or cubic metres per hour (m³/h), the flow rate must align with the slurry’s volume and transportation speed. Incorrect flow rate specifications can cause inefficiencies or overloading, resulting in bottlenecks, increased operational costs, and downtime.

The flow velocity must stay above a certain minimum value. If the flow velocity is too high, friction losses will increase. This may also increase pipe system wear. Flow velocities that are too low trigger pipe sedimentation. � Environmental conditions (temperature, humidity, altitude): Each pump is designed to operate under specific environmental conditions to ensure reliable performance and durability. For example, pumps must be hardened with heat-impervious components

in high-temperature environments. Additionally, high-humidity conditions require corrosion-resistant components to avoid rust and degradation. pH level: pH measures hydrogen-iron concentration. The slurry pH level is determined to ensure that the pump is

Figure 2. Xylem’s mining applications engineering team designs, fabricates, and installs hundreds of turnkey slurry pump systems each year for mines around the world. The systems can include the slurry tank, piping, and pumps. For tailings applications, Xylem can also design and fabricate filter presses or any additional water treatment systems that are needed.

Figure 3. Developing an efficient, durable slurry pump system requires slurry analysis to describe the solids concentration either by weight or volume. The analysis also determines if the slurry contains fine particulate, such as sand, or larger, coarser particles, such as quartz or limestone.

made from corrosion-resistant materials. For example, if the slurry is highly acidic, the pump is protected with a special epoxy paint, as a typical cast-iron pump will not withstand prolonged exposure to acidic contaminants.

Particle size and shape: Particle size is a measure of the percentage of particles in the slurry. The value is determined by sifting the solids through screens with varying mesh, then weighing each fraction. The particles’ shape is also categorised as angular or rounded, as this impacts wear.

Solids concentration: The concentration of the slurry solids must be measured either by weight or volume.

Gravity/density of solids: Analysis determines if it is a fine particulate, such as sand, or larger, coarse particles, such as quartz or limestone. Everything larger than 5 mm is considered coarse. Abrasive materials require pumps with specific wear-resistant materials.

Total dynamic head: Head is the amount of resistance the pump must overcome to move the slurry. Head is based on the distance the slurry needs to travel horizontally and vertically (elevation changes). This information determines the pump’s ability to lift the slurry, if needed, or push it through pipes over long distances. It is calculated based on the vertical distance the pump needs to lift the slurry, plus the pressure losses due to piping friction.

Chemical content: The slurry’s chemical composition dictates the pump materials needed to prevent corrosion.

For example, for high chloride content, zinc anodes protect the pump in addition to epoxy paint.

Slurry pump footprint: The total amount of space available for the pump determines its configuration (horizontal, vertical, or submersible). Along with configurations, the footprint guides the motor and the drive placement – above, behind, or beside the pump. It also helps select the best option to seal the shaft that connects the motor to the pump to protect it from the slurry’s contaminants and abrasive material. The water that seals the backside of the pump needs to be clean water – not slurry water, which causes deterioration. When determining the pump’s footprint, Xylem assesses how to get clean water from a tank or another source to the back of the pump. The shaft seal area commonly leads to failures if precautions are not taken to ensure that it remains free from contaminants.

Designing, fabricating, and installing an integrated, turnkey system

58 november/december 2025 // global mining review

Xylem’s mining applications engineering team analyses this information to design the best possible solution for each site.

The team designs all system elements – the slurry tank, piping, and the pumps. They design, fabricate, and install hundreds of turnkey systems each year for mines around the world. For tailings applications, Xylem also designs and fabricates filter presses or any additional water treatment systems that are needed.

One major benefit of having a slurry system designed professionally is reduced energy consumption. An efficient pumping system uses less horsepower. An increase in power consumption increases operating costs, as well as the mine’s carbon footprint. Additionally, a filter press with a treatment

system can be designed for water reuse, which is critical in water-starved regions.

Properly designed systems also minimise degradation from wear, as they minimise slurry pipe curvatures. When solids are transported in a liquid, if the flow changes direction due to a pipe curvature, the solids hit the back of the fitting and cause a pipe wear point that will weaken over time. A good slurry system design minimises changes in fluid direction to avoid causing premature fitting and valve wear.

Gathering data

Mining companies with teams of engineers and lab technicians often have the required system planning details readily available. For organisations that do not have the in-house resources to conduct detailed site condition evaluations, they must plan ahead – sending slurry samples to independent, third-party labs for testing. Sometimes, due to time constraints, the preferred slurry analysis methods are simply not possible.

On-site assessments

Xylem prefers to have its experts visit mining sites before designing a slurry system. Site visits allow the verification of important details, such as the precise dimensions of the pump footprint, and identification of potential issues that a customer may not notice. Site visits frequently reveal discrepancies between the pumping distances reported by the customer and the actual distance. If a customer says that the pumping distance is 20 ft, but the actual measured distance is 35 ft, that 15 ft discrepancy could mean the pump would be undersized by up to 5 hp. An undersized pump can quickly lead to performance issues that hamper productivity.

Ideally, it is preferable to receive CAD drawings, elevation images, or drone site survey footage from customers. When those details are provided, a site visit is not always necessary.

However, when a customer does not have the in-house resources to conduct site assessments and third-party lab data is not available, site visits are invaluable for gathering the details needed for efficient system design. For instance, Xylem applications engineers take slurry samples with a 5 gal. bucket.

Xylem’s in-house lab then analyses the sample solids to determine the nature of the slurry, which informs the size of the filter press used in the tailings application, the flow rate of the slurry, and the type of cloth used in the filter press.

Faster maintenance and upgrades

Additionally, Xylem’s applications engineering teams conduct on-site pump surveys to quickly meet future maintenance or upgrades needs. When there is a record of the horsepower, locations, model, and serial numbers of all a customer’s pumps, Xylem can provide immediate guidance when the customer needs future assistance.

If on-site parameters change, the mine should immediately contact the company that designed its slurry system because it may need an adjustment to accommodate the new specifications. For example,

increasing or decreasing production will have a significant impact on the slurry system’s performance. Also, changing slurry material mix due to mining in a different location or pursuing a different ore can have a significant impact on slurry system performance. To maintain maximum efficiency and avoid clogging, the supplier that designed the slurry or tailings system should be contacted to request a system audit. In some cases, the pump may need to be upsized to handle an increase in capacity or slurry solids density.

Additionally, if a slurry is running on a variable frequency drive, then settings are changed to slow the process down or speed it up, that shift can impact the system and require modifications. If a slurry is running too slowly, the velocity will not be high enough to keep the material in suspension. The solids will settle and start building up in the pipe, eventually resulting in blockage. Alternatively, running the process much faster than the original plan will result in excessive wear on the pump, piping, and fittings.

Optimised slurry system design maximises profitability

Designing an optimal slurry pump and extended tailings system ensures operational efficiency and cost-effectiveness. An optimised system reduces energy costs, wear and tear on the equipment, maintains uptime, and can create water reuse.

Enhancing productivity and extending the equipment lifespan will reduce maintenance costs and maximise profitability.

ining – it is one of the world’s oldest industries, and also one of the first to place a strong focus on the topic of operator safety. Over the years, technologies used to enhance safety systems within mining plants have paved the way for solutions which have since

become standard procedure, as well as being applicable to and used by other sectors.

Mining processes entail very high risks for both the operational continuity of plants and the operators themselves. This is reflected in accident figures associated with mining processes,

global mining review // November/December 2025 61

and at a European level, a range of serious accidents have impacted the mining industry: � Soma (Turkey, 2014) – An explosion and fire in an underground mine caused by methane caused 301 fatalities. � Handlová (Slovakia, 2009) – A methane gas explosion in a deep mine (approximately 330 m) led to 20 fatalities.

Wujek-Śląsk (Poland, 2009) – A deep methane explosion resulted in 20 fatalities.

Gleision (UK, 2011) – A mine tunnel accident, in which flooding caused four fatalities.

In the US, between 2011 – 2019, the Bureau of Labor Statistics (BLS) recorded 1030 deaths in confined spaces (tanks, silos, tunnels, etc.). In Canada, over 100 deaths per year are estimated due to confined spaces. For the mining sector, from 2004 – 2010, the US reported an annual average of 59 deaths in confined spaces, which was then reduced to 37 between 2011 – 2015, thanks to reinforced measures after the 2010 accident at Massey Energy, which resulted in 29 deaths.

According to Mine Safety and Health Administration (MSHA) data in 2024, there were 31 total deaths in the US in the mining sector, 20 of which were in metal and non-metal mines. When analysing data on mining disasters (defining a disaster as an accident that has experienced more than five deaths), data from the National Institute for Occupational Safety and Health’s Observatory confirms that most are due to explosions.

Looking at accidents without a fatal outcome, the statistics show a steadily increasing number of accidents since 2020, rising from 3193 to 3664 in 2023.

Maintenance as a driver for productivity

Figure 1. A remote operated robot for under conveyor belt jobs.

When analysed for its productivity aspects, the mining sector is an area where plants require constant cleaning to prevent materials from being deposited in places that could compromise the proper functioning of production lines.

The normal operation of plants results in the accumulation of debris and processing residues. The most common are: Dust and fines (dust, carryback): Fine particles that adhere to the belt return and accumulate on rollers and structure, often caused by wet or silica-rich materials.

Spills/fugitive material: Chunks of rock, ore, long piles that can fall or bounce off the belt, especially in loading/reloading areas.

Coarse material/lumps: Stones or larger debris which have fallen due to belt breaks or overweight, potentially dangerous for brushes and cleaners.

Depending on the type of plant, the frequency of the various cleaning operations also changes: Daily cleaning: Removal of visible debris and checking for blocked rollers and poor carryback.

Weekly/monthly inspection: Checking cleaners (tensioning and wear), cleaning around the structure, greasing bearings, etc.

Thorough structural cleaning: Periodic mechanised activities (e.g. booms and mini-loaders) for material accumulated under the belt, especially in underground or hard-to-reach areas.

It is important to emphasise that the correct maintenance of installations can prevent damage, malfunctions, and even accidents involving personnel. The most common damages are: accelerated belt and roller wear, mistracking, motor overheating, and fire hazards caused by material under the belt, which can ignite due to friction or sparks.

Conclusions

The use of robots working in high-risk areas, such as confined spaces or ATEX zones, is a fundamental first step in improving productivity and safety in the maintenance and cleaning operations of mining facilities. Raising the level of safety, and thus lowering or eliminating accidents, is a complex issue. While no-man entry robots are essential for explosion-hazardous areas (ATEX), it is equally important to emphasise that many jobs involve the presence of personnel who, in addition to machinery and robots, enable cleaning operations to be implemented. It is therefore essential that robots, personnel, and the industrial working environment are connected and digitise. The possibility of having 4.0 sensors mounted on board, having sensors worn by operators – to monitor, for example, any changes in vital functions or to receive voice commands (Smart PPE) – and also equipping the industrial environment with sensors on critical infrastructures (Smart Alert) enables to set up a worksite that is a digital ecosystem. Complete automation is achievable if robots can work in an increasingly robot-friendly environment where operators, should their presence be required, can be integrated and perform their tasks.
