EDITOR’S COMMENT Corruption is destroying Africa mining sector

A

recent development in which an international mining company pleaded guilty to corruption charges in Africa is worrying.

Corruption is a widespread problem in many natural resource-rich countries. Mining in these places is a contentious, graft-prone trade and enjoys poor reputation, epitomizing rampant loot of raw materials and crony capitalism while contributing to enormous environmental degradation and social unrest.

In fact, a 2017 report by Transparency International revealed that corruption occurs at the very start of the mining process, where key decisions are made about whether, where and under what conditions mining is permitted.

In many countries, rampant corruption afflicting the mining industry has led to a massive loss of public revenue, estimated to be worth hundreds of millions of dollars every year.

The corruption-related losses in these places blow a big hole in their state coffers and diminish the ability of their governments to provide public services like healthcare and education by reducing the funds at their disposal.

Art Director/Layout Augustine Ombwa Arobia Creative Consultancy austin@arobia.co.ke

In this way, graft plays a significant role in condemning these resource-rich nations to remain among the poorest in the world.

And this is why we should all unite to fight graft in the Africa mining sector.

Mozambique rules out abandoning coal mining for us to do this,” said Vales.

Vales guaranteed that, in the context of energy transition, mitigation actions are under way, aimed at developing nonpolluting systems of energy generation.

He said that among these systems there stand out renewable energies, including hydro-electric power stations, but also less polluting fossil fuels, such as natural gas.

T

he government of Mozambique has ruled out the possibility of abandoning the mining of coal as part of the energy transition advocated by the United Nations in order to meet the target for reducing carbon emissions by 2030. Permanent Secretary in the Ministry of Mineral Resources and Energy, Teodoro Vales said the government justifies this position on the grounds that coal remains a major Mozambican export, and thus makes a crucial contribution to the balance of

payments and as a source of foreign currency. The government also believes that the energy transition should always take account of the real conditions in the country.

“A lot is said about abandoning coal. But right now coal is the major contributor to the balance of payments, and in second place we have the heavy mineral sands.

So we cannot abandon these sources from one day to the next, because the necessary conditions must be in place

The current government, has set the ambitious target of producing an extra 600 megawatts of power by 2024, of which 400 MW will be generated by gasfired power stations, and 200 MW will come from solar, wind and hydro-electric power.

“For example, in the area of solar power, we have invested in a 40 MW solar station in Mocuba, 40 MW in Metoro and 30 MW in Dondo. These are just the solar stations, but there are also hydroelectric stations,” he said.

Zimbabwe to speed up reopening of Zisco Steel

T

he government of Zimbabwe has announced plans to speed up reopening of former industrial flagship Ziscosteel in time for the 2023 elections. Zimbabwe Iron and Steel Company is located just outside Kwekwe, in Redcliff, Kwekwe District. Over the years the company has faced many operational problems and corruption scandals. At its peak, the plant produced nearly 1 million tons of steel a year.

to reduce or liquidate two large debts totalling $340 million, including $240 million to a German bank. 54% of the company is now in the hands of Essar Africa Holdings Ltd (India-based). The government of Zimbabwe still holds 36% and a consortium of private investors holds 10%. Up to 3,000 jobs were saved.

The ZISCO group of companies include BIMCO, Lancashire Steel, Frontier

Steel, ZISCO Distribution Centre. All these companies are 100% owned by ZISCO. It gets raw materials (such as iron ore) from Ripple Creek mine which is about 14 kilometers from ZISCO. Up to 70 million tonnes can be mined. Up to 200 million tonnes of limestone can be found on an open cast mine which is a few meters from ZISCO. Zimbabwe also has reserves of up to 22 billion tonnes of coal.

The Company stopped operations in January 2008, following three successive power outages from the national grid coupled with cooling water challenges leading to the cooling down of Coke Oven batteries and subsequently the cooling down of the Blast Furnace.

Kuvimba Mining House Ltd., has been selected to revive one of the continent’s largest steel mills. The miner has been picked as the “investment partner”. It was wholly owned by the government of Zimbabwe, until in November 2010, it invited bidders for a 64% stake of the ZISCO group of companies mainly

Angola celebrates 37th anniversary of Mining Labor Day

A

ngola has marked the 37th anniversary of Mining Labor Day. H.E Diamantino Pedro Azevedo, the country’s Minister for Mineral Resources, Oil and Gas celebrated the day by highlighting developments achieved within the mining industry under the leadership of H.E João Lourenço, President of Angola. The Minister emphasized the resilience of the industry in driving Angola’s economic growth and in ensuring a better life for the population despite the impacts of the COVID-19 pandemic which disrupted worker mobility and productivity.

The Minister also highlighted the country’s success in implementing a new governance model for the mining sector to improve industry efficiency by reducing the government’s direct participation in a bid to boost foreign and private sector investments. The inauguration of the Saurimo Mining Development Center in the eastern Lunda Sul province, a Training Center for Diamond Evaluators and Pencillers, and the Technical Training Center for technicians needed for mining and industrial activities has shown

the resilience of the industry and the government’s willingness to improve the economy through boosting the country’s mineral production while pushing for local content.

In addition, the Minister revealed that Angola has increased its exploration activities for minerals including copper, nickel, cobalt, rare earth elements, niobium and phosphates which the country plans to utilize to drive the energy transition at domestic, regional and international levels. With the demand for such minerals expanding owing to an increase in the deployment of energy systems such as solar, battery storage and electric vehicles, mineralrich countries like Angola are expected to benefit massively from monetizing their resources. “As a result of the

confidence in our work, the result of the reforms initiated and implemented in our sector, under the leadership of H.E. João Lourenço, President of the Republic, and the consequential improvement of the business environment, we were able to bring to the country multinationals such as Anglo American, Rio Tinto, Tosyali and Pensana that come to add value to our flourishing mining industry,” stated the Minister.

Angola’s mining sector accounted for 1.6% of GDP as of the third quarter of 2021, according to research firm Statista, however, with the world’s sixth-largest diamond producer having only exploited 40% of its reserves and production of minerals anticipated to increase in years to come, the sector is expected to expand its contribution to GDP growth.

2022 field programme at Mutanga uranium project in Zambia begins

T

he 2022 field programme at Mutanga uranium project in Zambia has begun. GoviEx Uranium confirmed the report and said the programme follows the company’s flagship Madaouela uranium project, in Niger. The field programme will target key aspects that will assist to progress Mutanga towards completion of a feasibility study and potential subsequent funding and construction. It includes 15 500 m of infill drilling, with the aim to upgrade Mutanga’s Dibwe East resource from the inferred to the indicated category, extending the work completed by GoviEx in 2021.

The drilling is planned to use downhole percussion drilling to an average depth of 120 m in a nominal 100 m x 50 m grid. GoviEx has also commissioned 9 000 m of diamond drilling to obtain core samples for uranium assays that will be used to determine uranium

disequilibrium factors for Mutanga’s Dibwe East and Dibwe deposits.

The drilling will also provide metallurgical samples for process verification and optimisation test work and for geotechnical studies. As part of the 2022 field programme, a hydrogeological study will be conducted to find a reliable water source for the plant and to carry out the dewatering studies for the openpits.

GoviEx has also commissioned an update of the environmental- and socialimpact assessment and relocation action plan beginning in July. They also commissioned downhole logging services including calibrated gamma log used to correlate uranium grades, hole deviation and conductivity logs to interpret the geology.

As part of the company’s commitment to act responsibly in all activities it

Predictive Discovery Ltd releases further Bankan Gold drilling results

interpretation of the high-grade zone, including location, widths and grade as well as from multiple stacked lodes identified in previous drilling results.

“Predictive is now entering a new phase of its exploration with a greatly expanded drilling programme and the improved geological understanding that flows from it. These prospects are expected to add significantly to the Bankan Project’s mineral resource inventory.

P

redictive Discovery Ltd has announced further diamond drilling results at its Bankan Gold Project, located in Guinea. Bankan currently has an inferred resource of 72.8 million t at 1.56 g/t gold (Au) for 3.65 million oz of Au. The drilling included in the announcement targeted below the current deeper high-grade core at NE Bankan, which remains open at depth and along strike.

The company considers there to be significant exploration potential to

increase the resource base and will do so through an aggressive drilling programme over next 12 months.

Managing Director, Andrew Pardey, said: “These new results demonstrate the consistency of grade and mineralisation which evidently continues significantly beyond the bottom of the NE Bankan pit shell, further underpinning Predictive’s view that Bankan is potentially a Tier 1 gold mine in the making. In addition, the results confirm significant reconciliation with the company’s geological

“The company is also balancing more aggressive exploration with a best practice biodiversity management programme to ensure our stakeholders have the confidence we will develop this project in a way that mitigates any negative impacts. This includes defining a robust biodiversity management plan given Bankan’s proximity to the Upper Niger National Park and other sensitive sites.

“As part of this process, we are developing a detailed biodiversity management roadmap. We have activated a rapid ecological assessment, which is being conducted by leading ecological specialists and coordinated by a globally significant environmental firm. This work will provide a broad understanding of the environment surrounding the Bankan Project and will ultimately inform a more detailed environmental and social impact assessment in due course.”

Zambia seeks financial adviser for Mopani Copper Mines

Z

ambia’s state mining investment firm Zambia Consolidated Copper Mines – Investment Holdings (ZCCM-IH) is on the lookout for a financial adviser to reform Mopani Copper Mines (MCM), reported Reuters.

MCM, which is 100% owned by ZCCM-IH, owns underground mines, a concentrator, a smelter and a refinery at Mufulira mine site, open pits, a concentrator and a cobalt plant at Nkana mine site in Kitwe.

The investment firm is also seeking a private investor to help boost production at the copper mine. According to ZCCM-IH board chair Dolika Banda, the appointment of financial adviser is “imminent”. A new equity partner would be announced within the next six months

to a year. Since raising $1.5bn in debt to buy MCM in 2021 from Glencore’s subsidiary Carlisa Investments, Zambia has been seeking new investor for the mine to increase output.

“To own this mine requires billions of dollars and we can’t continue to be asking the Zambian treasury to be financing exploration, productivity and technology upgrades. ZCCM-IH, however, will continue to help MCM in servicing its loans and working capital, buying inputs in addition to working on “long-term solutions,” Banda noted.

Mopani Mines produces and sells copper and cobalt to the international market, being one of the biggest mines and exporters in the world. In brief

history, MCM produced 134,800 tonnes (148,600 short tons) of copper and 2,040 tonnes (2,250 short tons) of cobalt in 2003. At that time, MCM invested in a number of oxide copper projects at several of its properties, including an in-situ leaching project at Mufulira and leaching at Nkana, and has achieved significant production increases at its underground mining operations in Kitwe and Mufulira. Copper production from internal sources was supplemented by the purchase of some 18,000 tonnes (20,000 short tons) of copper in highgrade oxide concentrate bought from the Democratic Republic of the Congo, and 185,325 tonnes of copper concentrate toll treated from Copper-miner Equinox in 2007.

Phase 1 energy project at Endeavour Hounde mine complete

P

hase one energy project at Endeavour Mining’s Houndé Mine in Burkina Faso has been completed. Voltvision, the high voltage (HV) electrical data analytics business announced the successful completion. The results of this initial phase have proved so constructive that Voltvision has been commissioned to roll out the project to all of Endeavour Mining’s mines and development projects across West Africa.

This project hinges on Voltvision’s big data software solution, a program that has been designed by mining specialists and engineers to optimise energy consumption and improve predictive maintenance on all high voltage equipment used on mine sites. This software is coupled with a data extraction cube, a secure ‘plug-and-play’ analytics device installed on a mine’s network. This device extracts and transmits hundreds of energy-related data points to the cloud-based software using Wi-Fi /4G networks.

“The Phase One roll out of this project was intended to provide high resolution data extraction in support of existing data systems presented in mobile- and PC-based dashboards. This allowed the mine’s technical team to monitor incoming grid power quality and the power quality across the Houndé power system. It has also allowed the accurate recording and logging of power usage as well as the movement from source to point of use again across the whole HV and MV networks.

Understanding slurry means designing the process to suit the properties of the slurry

“Phase 1 of the project commenced in December 2021 when the Cube device was remotely installed across Hounde’s high voltage electrical network, with assistance from the Endeavour team. The ‘plug-and-play’ nature of the device allowed the project to commence with minimal hassle and zero downtime in production.

“In the four months since this installation, a wide range of data points, numbering more than 200 individual points, have been collected and analysed. Early analysis of this data has facilitated a clear and comprehensive understanding of how the mine’s electrical network is behaving and how power is utilised in real time. This has made it possible for the Endeavour team to identify hidden problems and inefficiencies and understand what changes are required to achieve greater energy efficiency across the entire operation. The correction of such efficiencies can deliver quick cost savings and CO2 reduction as well as edging closer to operational excellence.”

“Phase 2 is intended to identify further power savings opportunities; develop early warning mechanisms for grid outages; and extract demonstrable Scope 1 and 2 GHG emission numbers. Voltvision will also provide highly accurate asset management services on capital equipment using algorithms it has developed with leading machine learning universities to provide advanced warnings of performance changes and fault development.” said Manoli Yannaghas, Co-Founder and Managing Director of Voltvison. Voltvision’s electrical management software is in the process of being rolled out across the rest of Endeavour’s operations, as mentioned.

Yannaghas concluded: “Through this initial Phase 1, we have formed an excellent working relationship with Endeavour Mining and are exceptionally pleased with the results produced thus far. We look forward to further engagement and assisting the company in optimising its HV electrical asset base, realising cost savings and facilitating the decarbonisation of its mine and project portfolio.”

Indaba showcases steady ESG advances in Africa

“

Africa’s mining sector is showcasing a real shift from high-level carbon neutrality intentions to some exciting and practical first steps on the journey to a low carbon future. With the world’s eyes on the Investing in African Mining Indaba in Cape Town, it is heartening to see the technological progress being made in fields like hydrogen-powered mining trucks and mine-site renewable energy plants, according to Andrew van Zyl, director and principal consultant

at SRK Consulting. Speaking from the event, where SRK has been exhibiting and contributing to panel sessions, Van Zyl noted that the focus remains justifiably on environmental, social and governance (ESG) factors in mining investment.

“Reflecting how imbedded ESG has become in mining, the industry has more to show for its efforts each year,” said Van Zyl. “The mining industry in Africa

The tone of this year’s Indaba was significantly more upbeat, as buoyant commodity prices have given mining companies improved liquidity to back capital projects for new or expanded operations. This liquidity has also made it easier for lenders to contribute debt financing to mineral projects.

“Mining’s recent growth – despite the Covid-related lockdowns – has been fostered by the rapid evolution of technology,” he noted. “Within the global SRK network, we were able to continue building connections, even sharing virtual site visits as part of our intercountry collaboration.”

These digital communication channels are allowing a greater global appreciation of one-of-a-kind technological developments such as the hydrogen trucks in South Africa, said Van Zyl. At the same time, Africa can learn from countries like Australia about implementing hybrid power plants at mines.

He added that the ESG discussions at the Indaba were also likely to prioritise water stewardship on mines as an important strategy to address both operational risk and social licence to mine.

embraced as an opportunity to build stronger partnerships with communities.

He also pointed to the attention given by leading mining companies to the energy transition, and to creating a cleaner energy ecosystem that could stimulate inclusive development opportunities for the continent. Anglo American recently announced the launch of its end-to-end integrated green hydrogen production, fuelling and haulage system. This could reportedly remove up to 80% of diesel emissions generated on opencast mines. “The economic disruption caused by the Covid-19 pandemic highlighted how dependent so many economies are on mining,” he said. “In South Africa, it remains a cornerstone – even recently helping to raise the country’s investment ratings from negative to stable.”

faces and reconnect with people at this event,” he said. “The industry still faces many challenges to its progress, and these conference interactions are a great opportunity to share ideas and start finding solutions for mining operations, wherever they are located.”

he cautious optimism of delegates at this year’s Investing in African Mining Indaba was a positive sign for the continent’s mining industry, and once again highlighted the sector’s potential. “This year’s event again emphasised the fact that mining and agriculture are key economic drivers in economies like South Africa,” said Ralf Hennecke, Managing Director of Omnia Group company BME.

He noted that the impact of the Covid-19 pandemic was still being felt in mining supply chains around the world, including Africa. These had been further compounded by the ripple effects of Russia’s invasion of Ukraine. There was still a significant supply constraint in global shipping services, for instance, raising both costs and turnaround times in mining logistics. “As a supplier of critical mining inputs like explosives, BME deals constantly with supply chain issues arising from factors ranging from weak infrastructure to border efficiency,” he said.

“The enthusiasm accompanying the Indaba shows how much has been achieved, and how much more value can still be generated from minerals – to stimulate inclusive growth across Africa.”

This year’s Indaba is the first opportunity for delegates to meet face-to-face since the event was held in February 2020.

Hennecke noted that the engagement with delegates at BME’s exhibition stand at the Indaba showed the importance of regular and direct contact. “It has certainly been valuable to meet new

contributes to gradual improvements in the cost of doing business in these economies.”

The event also provided a platform for governments to showcase their progress in developing conducive conditions for investment. In some cases, these efforts have borne fruit, said Hennecke, but a level of uncertainty still held many investors back. Among the areas where mining companies sought greater predictability were taxation, royalties, resource nationalism and permitting.

BME Michelle Fedder at Mining Indaba

“The Indaba continues to reflect the commitment of the mining sector to environmental, social and governance (ESG) interventions, which paves the way for more collaborative relationships with stakeholders,” he said. “It is worth adding that mines are generally well

supported by their key suppliers when it comes to achieving their social licence to operate, including the engagement and upliftment of host communities.”

BME’s Marketing Manager, Michelle Fedder said that in its interactions with Indaba delegates, BME was able to share its commitment to key United Nation’s Sustainable Development Goals – in alignment with the values of the Omnia Group.

“In our contribution to mining around Africa, we continue to drive change by innovating to enhance life, together creating a greener future,” she said. “This can be achieved through collaborative, sustainable practices that build the growth and resilience of the continent’s mining sector.”

Sleipner’s new DB product family attracts orders from Finland and Africa – even before official launch DB80 in Burkina Faso

S

leipner updated its entire DB product family last year and has unveiled two new narrower models. The new DB80 and DB130 models have a maximum payload of 80 and 130 tonnes respectively, and both are equipped with Sleipner’s patented loading ramps. The new product family received an exceptionally positive reception even before the official launch, and the first orders have already been delivered to Finland and Africa end of year 2021.

“Our new models have been engineered in response to feedback from our customers. For example, we previously offered a 120-tonne model, but customers requested a narrower version. Accordingly, our new DB130 model is less than 10 metres wide and the smaller DB80 model is just over 8 metres, despite offering slightly higher

payloads. The new models are now suitable for use on narrower roads,” says Teijo Höylä, Product Manager at Sleipner.

Sleipner had already negotiated the delivery of previous-generation DB models to Africa before the outbreak of the pandemic. Following the resulting delivery delays, it was natural to upgrade the order to the new DB models already before their official launch.

“We thought of the customer’s best so they could get newer and even better features for the same money. For example, the new models also feature full remote control and telemetry. Data can be automatically collected from the machines, allowing us to respond rapidly and remotely to possible faults and even perform software updates. There is no longer the need to fly all the way to Africa

DB130 in Finland

to investigate the tiniest of faults,” Höylä describes.

Another new feature on the new models is the patented loading ramp that follows the surface of the ground. The solution reduces service and maintenance costs compared to traditional models and minimises stress on the loading ramp during loading.

Viewed from above, the modular load beds on the two new models are largely similar – the main differences are the payload capacity and width. The decisive factor in choosing between the two models is the type of dozers they will be used with. The DB80 model can transport dozers up to D10T/D375 and the DB130 up to D11T/D475.

“The new models have been engineered for use in all conditions, from the coldest to the hottest climates. Mines are located all around the world, and our customer base is global, so Sleipner products have to operate reliably everywhere. When engineering structures and components, we make sure that they all have a long service life and low life cycle costs, that spare parts are available globally, and that they are easy to service and maintain,” Höylä adds.

Sleipner’s DB series enables fast and safe loading and transport while adding flexibility to daily production planning.

Drills and bulldozers can be picked up and delivered efficiently directly to where they are needed.

INSIGHT

The power of renewal - current status of the energy transition in Africa

By Kieran Whyte, Partner, Head of the Projects Practice and the Energy, Mining and Infrastructure Industry Group, and Zahra Omar, Knowledge Manager, Baker McKenzie Johannesburg

P

ost-pandemic, new solutions are being implemented to address Africa’s power challenges, which have been hampered by a lack of competitive funding, the dire state of the continent’s utilities infrastructure, and the need for energy policy and legislative reform to boost investment in the sector. Such solutions have had to consider the energy transition and the utilization of renewable energy, the focus on smart power technologies, the role of green hydrogen and ammonia, and the global drive towards a decentralized, decarbonized, affordable and secure energy supply that addresses climate change and stimulates economic growth.

Developments in Africa In order to address the urgent energy needs across Africa, the African Union (AU) Commission and the International Renewable Energy Agency (IRENA) agreed in 2020 to work together to alleviate the impact of COVID-19 and ensure that Africa can meet its development goals. According to the AU, the focus of this agreement was on supporting the development and adoption of innovative renewable energy technologies, improving access to energy, building more resilient energy systems, mobilizing international support (including from the private sector), developing more extensive and more robust power markets, and encouraging cross-border trade of renewable power.

IRENA predicts that with the right policies, regulations, governance and access to financial markets in place, sub-Saharan Africa could meet 67% of its energy needs by the year 2030. A strategy presented to the United Nations Framework Convention on Climate Change before COP26 in November 2021 showed that Africa is also committed to reducing the continent’s contribution to greenhouse gas emissions by 32% by the year 2030.

Smart power innovation Africa has a role in innovating smart power solutions for a post-COVID-19 world and ensuring a sustainable and diversified energy mix. There are increasing opportunities to implement new technologies and localized energy generation systems within developing economies. The combination of the rise of cost-effective renewable energy, decentralization of energy production, and improvements in energy storage, smart metering, and other digital technologies are revolutionizing the way power is generated and consumed.

Across the continent, new systems and networks are being designed around future environmental stressors and energy demands without having to consider the limitations of old infrastructure. With the advanced use of mobile technology in Africa and the lack of existing electricity transmission capacity, these developments allow

18

communities in Africa to gain access to power without needing to consider the traditional model of centralized generation and transmission of power.

Decentralized power solutions In Africa, the most noticeable trend has been the transition towards decentralized power solutions. Solar home systems have also moved from being a niche sector dominated by non-governmental organizations (NGOs) to being considered a mainstream investment led by the big players. Energy investors have traditionally focused on grid-scale generation but are now investing in, buying or developing businesses in this area in Africa. Instead of a lack of scale being an obstacle to getting the market going, companies have been developing models to scale up the sector and build businesses or portfolios. These initiatives have been mainly financed on corporate balance sheets, but bankers are also taking notice and looking at how to put in place bankable business structures.

Power Africa Power Africa, a United States (US) government-led program that focuses on addressing Africa’s access to electrical power, has provided significant support to African countries since its launch in 2013. Since then, Power Africa has helped bring more than 5,500 megawatts (MW) of cleaner and more reliable power

generation and first-time electricity to 127.7 million people across sub-Saharan Africa. The program is a partnership between the US government and the governments of Ethiopia, Ghana, Kenya, Liberia, Nigeria and Tanzania, and private sector. The African Development Bank Group (AfDB) has partnered with the US Development agency USAID to shape the Power Africa initiative and, according to the AfDB, Power Africa interventions have included investment loans, reforms, advisory and guarantees, with a commitment of at least USD 3 billion in the six priority countries.

particular structures that cannot easily be implemented without the involvement of these institutions. There remains a need for more local-led development of the sector, supported by appropriate tools and resources. One example of this would be Kenya’s National Electrification Strategy, launched by the Government of Kenya and the World Bank. It uses a geospatial tool to identify the leastcost options for securing the delivery of electricity to houses and businesses in Kenya. It also outlines the vital role of private sector investment in providing off-grid solutions to remote areas.

Multilateral and development finance institutions Multilateral and development finance institutions (DFIs) have been important allies in developing and mobilizing funding in Africa’s renewable energy sector. They have provided funding for projects, but they have also structured successful programs to address potential risks. Examples of renewable energy success stories that have been supported by DFIs in Africa include Zambia - the first country in sub-Saharan Africa to implement the Scaling Solar program, with support from the World Bank Group through the International Finance Corporation (IFC). The program facilitates the development of privately owned, utility-scale solar PV projects and enables governments and utilities to procure solar power cheaply and efficiently.

Government programs Governments across Africa have acknowledged the need to reform their legal and regulatory frameworks and have introduced programs and incentives to boost investment in innovative projects in the power sector.

For example, Cameroon has launched an agency to manage the public electricity transmission system, Société National de Transport de l’Electricité (SONATREL). This system will support the vision of attracting around USD 10.6 billion in investment to deliver on its energy targets.

Zambia’s solar PVs success led to the program’s extension to Senegal.

Active engagements now include Cote D’Ivoire, Madagascar and Togo. In February 2022, Niger announced the list of prequalified bidders for the design, financing, construction and operation of a grid-connected solar PV plant with the capacity of 50 MW. The 2019 scaling solar PV tender in Senegal set a new price benchmark for the region and made solar energy Senegal’s cheapest energy source. Similarly, the German stateowned investment and development bank KfW backed the GET-FiT program, which has enabled several projects (in a particular run of the river hydropower projects) to be developed in Uganda and Zambia with extension to Mozambique and other countries under consideration.

Local-led development DFIs and multilateral programs, however, take time and resources to implement and are dependent on

In 2021, the World Bank issued a report - Review of the South Africa Renewable Energy IPP Process, which noted that the country held a central position in the global debate on effective policy instruments to accelerate and sustain

private investments in renewable energy. As such, the World Bank reported that the country’s Renewable Energy Independent Power Producer Procurement Program (REIPPPP), had been able to attract substantial private sector expertise and investment into grid-connected renewable energy in South Africa at competitive prices. The report noted that by 2021, 64 projects had been awarded to the private sector, and the first projects were already online.

A total of USD 14 billion in private sector investment has been committed, which will generate 3922 MW of renewable power. In the latest development around the REIPPPP, in April 2022, the South African government issued a request for proposals from bidders for the supply of 2600 MW of renewable energy - split into 1600 MW of onshore wind and 1000 MW of solar power.

Powering up Africa If the continent can build on these initiatives and is successfully able to address its power crisis through the widespread use of renewable energy solutions and smart power technologies, it will ensure that all who call it home can plug in to clean, sustainable and cost-effective electricity in the years to come. This will power up Africa’s post-pandemic recovery and provide innovative examples of how successful partnerships, projects and policy instruments can be utilized to facilitate the energy transition.

COVER STORY

Water in the digital age: Netilion Water Network Insights

T

he treatment of mine water has evolved in the past 20 years. In the past these operations relied on large teams of maintenance & operational staff to carry out time consuming manual measurement activities to ensure that plant and networks were operating safely. Technological innovation has introduced a variety connected devices and systems, this provides plant owners with the ability to modernize their water treatment plants for remote operation to help meet market demands and increase

operational productivity, accuracy, and efficiency.

Population growth, industrialisation and climate change intensifies water scarcity.

Communities across the world have an urgent requirement for safe, reliable, and affordable water and wastewater (W/ WW) treatment. The demand for W/WW treatment is non-cyclical, Governments, municipalities, private sector as well as the Mining industry will continue to invest in new and existing infrastructure to meet

22

the increase in regulation requirements.

Mining is a water-intensive process, with water being used for mineral processing, dust suppression, slurry transport and employees’ needs. 10% of the mining industry’s CAPEX is spent on waterrelated infrastructure according to the International Council on Mining & Metals (ICMM) and the International Finance Corporation (IFC).

The primary challenge for mine operators

www.fmdrc-Zambia.com

is water treatment, and ensuring they find a balance between guaranteeing compliant effluent quality whilst minimizing costs. Mine water treatment plays a crucial role in mining operations, whether in guaranteeing a ready supply of fresh water for workforces, or in support of vital processes such as separation.

However, procurement and treatment of the needed volumes of water are not the only challenges. Treating wastewater for safe discharge is equally complex. All of these challenges are compounded when operating in a remote location.

The Endress+Hauser portfolio offers multiple solutions for mine water treatment. Endress+Hauser offers a broad range of sensor instrumentation to support optimal mine water processes, from monitoring of desalination of extracted water, to industrial water preparation, to treatment of water for discharge.

Water’s journey is endless. It often travels long distances through huge pipelines in remote areas without any other infrastructure. To guarantee sufficient water quantity and quality, active management is needed.

This is where our battery-powered Promag W 800 makes your life easier. It provides everything you need to maintain full compliance with legal requirements while increasing your operational efficiency. Whether in urban or remote areas, in a desert or in the tropics – the accurate measuring and billing of drinking and process water consumption is becoming increasingly important.

(SWAS) Steam and Water Analysis System

Ready to transform your water network with IoT? IoT technology solutions like Netilion can provide enormous benefits that were not previously possible.

We believe that the Mine operators should look to the Internet of Things (IoT) for technologies and solutions tailored for the improvement of their operations.

The IoT landscape connects digital objects such as sensors and flow meters to the internet, turning them into ‘smart’ assets that can communicate with users and application systems. This allows for more efficient process control and optimised network management.

General water monitoring operations that were previously manual and inefficient can now be automated, continuously reporting on their own status in real time.

Endress+Hauser is a partner who understands the needs and demands of the water in the mining industry. We have made it our priority to create practical solutions to meet your needs while supporting optimal operation on your end. Netilion Water Network Insights is one of our cloud-based solutions that is certified and is a vendor-independent IIoT ecosystem. This solution helps users continuously monitor and improve their processes and procedures – whether in the field or in the control center.

Netilion Water Network Insights enables you to optimize your processes across the entire water cycle while collecting all important measuring variables and displaying the data in a customizable visualization. This allows you to react quickly to incidents and save on operating and energy costs.

The volume of information that can now be transmitted is truly astounding, as are the advanced data visualisation solutions that decrypt this information and turn it into valuable outcomes for a wide variety of mining stakeholders.

Proline Promag W800

Endress+Hauser has developed the new Promag W 800 with battery power, precisely for such applications. This electromagnetic flowmeter allows versatile and autonomous use even at locations without power supply: Water quality monitoring is also an important aspect for mining operators. It consists of several key parameters (pH, turbidity,etc) to ensure treated wastewater meets environmental guidelines. These parameters are either measured online by process instrumentation or by manual grab sampling, which may examine a composite sample over a weekly period.

Most modern treatment plants will have automated online monitoring systems at the outlet of their treatment plant. With ad hoc or manual-based measurement, it’s easy to miss a pollution event which may cause environmental damage.

Netilion Water Network Insights ensures full transparency in mining water treatment around the clock and can be used for reliable monitoring of water quantity as well as other parameters like pressure, temperature and level. Netilion Water Network Insights connects all levels of a water treatment system and offers service providers and water associations a tailor-made solution from a single source. These include everything from field devices, components for data transfer, data recording, data archiving and data evaluation as well as unique forecasting functions.

In an environment where water security is no longer a guarantee, IoT technology has been proven to boost operational efficiency and provide smart investment decisions. As mining operators make leaps and strides in their use of IoT technology, we encourage you to partner with Endress+Hauser and not be left behind.

The delegation comprises 20 South African firms that specialise in the latest mining technologies, engineering, equipment, services and technical skills.

It is the fourth time that South Africa is represented by an official country pavilion at the event, which has been around for 17 years.

The largest expo and conference in the heart of the Copperbelt dedicated to the mining and industrial sector, DRC Mining Week will again gather some 600 mining executives from 80 mining houses and operators, 4000+ attendees, of which 70% will be international, more than 80 expert speakers, and the in- and outdoor exhibition will host German and South African country pavilions.

South Africa’s sought-after skills “We are thrilled to have such a strong showing by South Africa at our first live, in-person show back in Lubumbashi since the pandemic; we regard it as a huge homecoming for all of us,’ says Elodie Delagneau, event director of DRC Mining Week.

“The technical know-how, experience and specialist knowledge of our South African exhibitors are in great demand across the mining landscape on the continent, and in the DRC in the particular, as it is fast becoming a key mining destination as the world’s largest producer of cobalt”.

Cobalt is a critical mineral used in the production of lithium-ion batteries found in almost all smartphones, tablets, laptops and electric vehicles. The DRC reportedly has untapped mineral deposits estimated at US$24 trillion. It is Africa’s largest copper producer, the second largest producer of diamonds and has significant deposits of gold, zinc, tin and potash.

EVENT - DRC MINING WEEK

DRC mining poised for new era of compliance

I

mproving global economic conditions – alongside growing sustainability demands – are set to inject a revived energy and much lively discussion into this year’s DRC Mining Week.

According to SRK Consulting DRC country manager Susa Maleba, the mining landscape in the Democratic Republic of Congo (DRC) is buoyant, stimulating both exploration and mine expansions. At the same time, there is growing pressure on mining companies in the country to align operations with local regulations and global customer expectations.

“The international scramble for battery minerals is providing exciting opportunities for economic development in the DRC, as mining can help build secondary and tertiary sectors,” said Maleba. “It is important for this development to be sustainable, however, and the country’s mining framework is becoming more formalised to achieve this.”

He noted that the changes in the DRC’s Mining Code were beginning to deliver positive results, in terms of its focus on environmental and social impacts, and regulations to develop local service providers to the sector. With SRK’s Lubumbashi office set up over a decade ago, and now majority-owned

by Congolese professionals, it was well experienced in the local industry and fully compliant with the latest legal requirements, he said.

“In an exciting strategic initiative, SRK Consulting DRC has been working closely with our SRK colleagues in China and South Africa, to strengthen our offering to clients here,” he said.

According to Pengfei Xiao, principal consultant and managing director of SRK China, his office will be helping develop links with clients in the DRC. An experienced resource geologist from the China office, Li Frank Feng, will focus on building relationships with Chinese mining companies working in the DRC, said Pengfei.

This was putting the whole supply chain of various industries under the spotlight, with miners looking to ensure compliance with ESG benchmarks. Jordaan said these issues were likely to be among the key topics highlighted at the event.

“With growing interest from China in this region of Africa, we are committing resources to build these relationships,” he said. “DRC Mining Week will give us a valuable opportunity to understand more about the mining environment in the DRC, and to meet important players in this market.”

Providing SRK Consulting DRC with a strong link to SRK in South Africa, partner and principal environmental scientist Wouter Jordaan is also a director of the DRC office. Jordaan noted that delegates to the DRC Mining Week were also likely to discuss the importance of technological advances in the sector, and how these could improve mines’ efficiencies and sustainability indices.

“As old mineral processing plants are being replaced or upgraded, there is scope to include equipment which consumes less energy – thus reducing carbon emissions,” he said. “Solutions for cleaner energy supply, and better reliability, are also being considered; as their usage grows, the country will see more specialists in these fields setting up operations locally.”

Another topical issue in the DRC recently has been the accuracy of resource and reserve estimations presented by companies to government. After a period of adjustment, mining companies were aligning themselves to the range of changing requirements.

“Players active in the DRC are also coming to terms with global expectations relating to environmental, social and governance (ESG) factors that underpin their mineral production,” he said. “Endcustomers for battery minerals – such as vehicle manufacturers – are increasingly sensitive to public opinion and industry best practice on ESG matters.”

As an exhibitor at DRC Mining Week, SRK Consulting DRC was looking forward to broadening its network among local mining firms and stakeholders. Led

by Maleba and the company’s chairman, Dominique Sambwa, the SRK team was also planning to have colleagues from SRK offices in China and South Africa at the event.

Water quality was a continuing focus, as environmental laws were becoming tighter and were being more stringently enforced. Mines were making better use of water resources by re-using more and discharging less – as well as closely managing their environmental impacts.

Aggreko celebrates 60 years and looks back at pioneering some big changes for mine power and cooling Aggreko Renewable Project at Bisha Mine in Africa

A

s part of its 60th birthday, the world’s leading provider of mobile modular power, temperature control and energy solutions – Aggreko – is also reflecting on its entrance to mining more than 30 years ago. Aggreko, which celebrates its 60th birthday this year, entered the mining industry in 1991 and about a decade later pioneered modular cooling in underground mining.

Aggreko Australia Pacific Managing Director George Whyte said the Netherlands-born company – now active in about 80 countries globally – has played an evolutionary role in mine power and temperature control.

“In 1991, Aggreko secured its first ever mining project, which was at the Benambra zinc and copper mine in Victoria, Australia,” Mr Whyte said. “At the time we were the only company to put 1MW of power technology into a modular container. Later in 2001 we pioneered modular underground mine cooling in the rental market, also in Australia. Prior to that, mines would purchase fixed

cooling and ventilation systems for their operations.

“Some other mines we supported early on included Mt Dimer, Youanmi, Century Zinc, Granites Gold Mine, and the Olympic Dam expansion – which is Australia’s largest open pit mine. Some of these mines are still around today.” Mr Whyte said energy services at mines had expanded since then.

“Where we once supported mines operationally with their short-term power and cooling needs, we organically developed into an engineering solutions provider, now active at more than 300 mines globally. Over time, our solutions have also become more complex from providing airflow modelling for underground cooling and ventilation to providing fully hybridised micro-grids.

“Of the limited number of off-grid renewable power plants in the world, Aggreko owns and operates three of them, and this is something we are very proud of. Where it was once common for miners to own and operate their own power plants onsite and for us to supply bridging power, it is becoming more common for us to build, own, and operate the power plant for a mine’s life.”

Mr Whyte said digitalisation has been one of the biggest transformers of the mining industry, as it also assisted with emissions reduction and safety improvements.

“Digital technology provides the data needed to reduce unpaid down-time on mine sites for instance or discover how solar and batteries behave under cloud cover,” he said.

Aggreko Global Head of Mining, Rod Saffy, said Aggreko was a truly global power provider and its experience in a wide variety of industries, applications and locations were part of the company’s success.

“Aggreko is truly a global company – and consistency across our businesses practices, has earned us a reputation for having the highest ethical, environmental, equipment and safety standards wherever we go in the world,” Mr Saffy said.

Aggreko has a team of more than 6000 people who operate across 80 countries.

It has a diverse team including engineers, data scientists, technicians, and power station operators – who demonstrate there aren’t any conditions too cold, hot, or tough to operate in.

A recent project included staff enduring extreme environments of the Andesmountain ranges in Salares Norte, Chile to establish a hybrid and solar power plant 4500 metres above sea level. Another project saw teams transport equipment via treacherous icy roads to provide 6.5 MW of power and heating to a silver mine in British Columbia, Canada. It was there that within three months Aggreko installed and commissioned a virtual LNG fuel supplied power plant with a heat recovery system. The team also operates in hot climates like Africa and Australia where they establish power plants in the soaring heat or desert.

Mr Saffy and Mr Whyte believe mining is at the forefront of technology and innovation, and the progress being made in the industry paves the way for other global industries such as manufacturing,

Aggreko Mining Power Station at Project in DRC Africa

construction, and major events.

“The mining industry has some of the most robust environmental and safety standards in the world and the innovations in the industry are truly exciting,” Mr Saffy said.

Aggreko’s latest technologies include its 1300 kW Ultra-Low Emissions Package – a world-first power generation system which effectively eliminates up to 99% of all controlled emissions from diesel generator exhaust streams. Emission levels are 90% lower than the next best available technology on the market.

Other technologies the company has either deployed or developing, include: • Modular solar power • Organic Rankine Cycle technology

•

(heat from generator exhausts converts into useable energy) Renewable energy solutions (such as wind farms, solar and hydro power) Mobile wind solutions and pumped, mechanical and flywheel energy storage Fuels such as hydrogen and biofuels (which will become more prevalent in the next decade and can be switched into Aggreko’s modular power generators).

Aggreko has a net-zero emissions goal by 2050 and has a 2030 target to reduce diesel use in its customer solutions by 50%.

oday, more than ever countries, organisations and industries are committed to Environmental and Social Sustainability strategies (ESS) to decarbonise our planet. In industry, becoming energy efficient is seen as an enabler of de-carbonisation, however, sustainably reducing energy usage and costs without compromising product quality or operational productivity remains challenging. Recent studies by the International Energy Agency (IEA) indicate that industrial applications account for 30% of the world’s electricity consumption with an estimated 300 million-plus electric motors globally consuming 65% of all industrial electricity. Sustainable energy efficiency and productivity improvements cannot be achieved overnight and is a concerted effort over time.

processes, and unreliable and costly supply chain by bringing the innovations of our manufacturers to end-users in Southern Africa, supported by people passionate about service”, says EM’s Head of Business Development, Rikus Botha.

Applying a Variable Speed Drive (VSD) to both Variable Torque (VT) motor loads such as pumps, fans and compressors or Constant Torque (CT) motor loads, such as conveyors and mills, have the potential to result in energy savings, as well as productivity improvements.

ElectroMechanica (EM) has the vision to advance the lives of every person in Southern Africa through the efficient electrification and agile automation of industry at scale, digitally and sustainably.

“Our purpose is to solve problems such as unsafe power distribution, inefficient energy consumption, manual electrical

However optimal electricity savings are most often achievable through VSDs applied to VT motor loads. “VT applications are frequently oversized to ensure the future expansion of a system is possible or to counter design uncertainties and other anomalies in industrial processes and systems,” says Rikus Botha. Either way, a VSD solution applied correctly has the potential to pay for itself from the monetary savings generated through reduced electricity consumption.

EM has been the exclusive distributor of the Delta Industrial Automation range in SADC since 2006. The product portfolio is extensively supported through EM’s stockholding, training, technical support and System Integrator partners. “Delta is proud of the long-standing partnership with ElectroMechanica and is pleased to deepen the collaboration with the launch of the Delta Medium Voltage (MV) VSD range in Southern Africa”, adds Paul Lee, Business Development Director of MV Drives at Delta Electronics.

The MVF23 and MVF20 series are suitable for both VT and CT

electric-motor loads in the industry. The proven Cascaded H-bridge topology and switching technology employed in the MV VSD solution enables near-sinusoidal output motor waveforms reducing motor losses, vibrations, torque pulses and overheating. This capability ensures that the MV VSD solution is widely suitable to be matched with new or existing induction, slip-ring or synchronous motors in retro-fit applications where Direct-On-Line systems are converted.

The MVF23 and MVF20 series consist of multiple low voltage modular power cells connected in series (cascaded) to achieve the required motor voltage output integrated with an in-panel low harmonic phase-shifting transformer which can also be used as a step-down transformer to match supply and motor voltages where required. This highefficiency phase-shifting transformer meets IEEE-519 compliance and ensures overall system efficiency >96.5% with the inherent power-factor correction capability of the VSD also ensuring an input supply power factor >0.96 throughout the electric-motor load range.

The small footprint of the MVF23 series makes the challenge of finding space for

a retro-fit VSD in existing MV rooms a thing of the past. Both the MVF23 and MVF20 series also require no rear or side entry to perform repairs or maintenance which means the solution can be installed against walls or placed backto-back to optimise space in existing rooms. Supply and motor cable entry is also possible from the top, bottom or side of the VSD if required.

“A number of normally customised options are included as standard options to optimise uptime, safety and reliability”, adds Rikus Botha. These include an integrated 10” HMI (Multi-language, full colour touch screen), IP42, Conformally Coated boards, Mechanical keyinterlock (spare lock and key provided for switchgear integration) and EtherNet/ IP as the standard CI Protocol. The HMI also provides a fault-finding interface with advanced status messaging, indicating the current operating conditions of the system.

The MVF23/20 has the option to exist as a standalone solution or to be integrated with an overarching PLC/ SCADA system with any of the major CI Protocols available as options (ProfiNet, Profibus DP, DeviceNet, ModBus RTU).To further enhance uptime both the MVF23 and MVF20 series have

automatic power cell bypass as a builtin option that can be activated. In the event of a power cell failure, the system immediately pin-points and indicates the faulty cell, automatically bypassing the faulty cell and the additional cells to balance the output voltage. Although this action will reduce the output torque, the VSD is allowed to operate until such time that the repair can be carried out conveniently.

Redundancy options are also available where an additional 3 power cells are integrated into the design for applications in which the output torque needs to remain at 100%.

All MVF23 or MVF20 VSD solutions sold

by ElectroMechanica are engineered to order in partnership with Delta Electronics application engineers taking supply and application requirements into account. All solutions are individually tested to 100% load and capacity, and according to the relevant End-User standards in Delta’s state-of-the-art MV factory and testing facility in Jiangsu, China. EM also invites customers to attend Factory Acceptance Tests or facilitate attendance virtually.

FEATURE XRF analysis for conveyor belts

Ore Sample Data Delivered Online in Real-time The traditional technique of taking ore and material samples to the laboratory for testing is misaligned with the reality in the present atmosphere. The accent is on cost containment, improving efficiency, enhancing costs and reducing environmental footprint. It has been observed that mining and mineral processing companies are adopting on-line analysis as an alternative, with X-ray Fluorescence as one of the techniques.

orldwide, conspicuously, in most mines ore grade has been dropping. Highly valuable deposits in shallow areas, which were easier to mine, have been depleted.

As a result, surface mines are going underground, and underground mines, ultra-deep. Usually, mining in these areas comes at a colossal cost – increasing operating expenses, on top of safety and environmental risks. This is reflected on the balance sheet. Yet, despite this challenge, as businesses, mining companies have to remain profitable and compliant. A tried and tested approach at the disposal of mining companies is adopting techniques that can ensure that their operations are cost-effective, profitable, safe, and environmentally friendly.

Among a host of means worth exploiting is the early sorting of materials or ore in the mining and mineral processing chain to eliminate waste rock and improve ore grade, which optimises mineral recovery.

Most importantly, in this way, wastage of resources such as chemicals, water, and energy used on crushing and screening is reduced (crushing and screening are energy-intensive - energy constitutes a third of a mine’s operating expense).

On-line analysis Noticeably, trends worldwide in mining projects substantiate that on-line belt

analysis is a viable alternative technique for monitoring ore grade. In online analysis, there is a wide range of options readily available, mainly: XRF (X-Ray Fluorescence), PGNAA (Prompt Gamma Neutron Activation Analysis), and LaserInduced Fluorescence (LIF).

It has to be pointed out that every method has its own merits and demerits.

The merits are a result of using a suitable technology for the intended field of application. Otherwise, the wrong usage is tantamount to the folly of using a square peg in a round hole – the odds of getting the desired outcome are zilch.

X-ray fluorescence (XRF) Fascinatingly, there is growing confidence in XRF as one of the options in on-line belt analysis. XRF is a nondestructive analytical technique used to determine the elemental composition of materials. The instruments used are capable of acquiring geochemical data rapidly. In no doubt, the benefits of XRF become more evident when the limitations of traditional methods are thoroughly analysed.

Traditional methods fall short As already stated, in the mineral processing value chain, the earlier the quality and grade of the ore or any material transported via a conveyor belt between various stages is determined

32

the better. Ideally, this should be carried out by taking several samples consistently and sending them to the laboratory as and when needed.

Nonetheless, in reality, the traditional method of sending samples to the laboratory for analysis falls short. There are always delays in time for delivery and sampling errors, out of kilter with the current realities in the mining sector.

Regarding sampling errors, there is always the possibility of discrepancies in the material flow recorded periodically (minute by minute or hour by hour). It is wrong to assume that the material will be homogeneous. The rule of the thumb is using a technique in the correct application. Otherwise, it won’t have the desired results.

The convenience of on-line analysis XRF technique On-line XRF analysis, using the technique of XRF in this context, guarantees non-destructive, accurate, real-time measurement and analysis data continuously, in time, of almost the whole volume of material on a conveyor belt. In most cases, correct usage ensures that elementary sample errors, which are inherent in traditional sampling methods, are eliminated or significantly minimised. What’s more, the data is available, right at the fingertips of process engineers as and when needed.

www.fmdrc-Zambia.com

Application and type of material determine choice

Letšeng Diamond Mine in Lesotho (image :TOMRA)

This informs the decisions they make.

In XRF, the elemental composition of a sample is gauged by measuring the fluorescence X-ray (secondary ray) using analysers. The primary X-ray targets a sample, which emits a secondary ray with a set of X-Ray lines (fingerprint) unique to a specific element.

Small wonder, XRF spectroscopy is widely regarded as the technology of choice where there is a need for both analysis of quality and quantity of material composition. XRF analysers positioned above the belt (cross-belt analysers) are more convenient as a wide part of material and ore flow is exposed. Small wonder, increasingly, XRF is enjoying usage in a wide range of commodities such as iron, chrome, titanium, copper, zinc just to cite a few.

Massive gains In a word, when used in a correct application in mines and processing plants, there are massive gains to be had in early sorting through XRF: • Cutting costs (energy, water, and chemicals, amongst others) by ensuring that waste rock is not erroneously sent for phases of crushing, grinding, and flotation; • Delivers immediate results (the adage time is money is not a cliché in mineral processes); • Timely interventions where changes are needed; • Optimises process efficiency; and • Consistent product quality.

All told, from the aforesaid, in the mineral processing chain where there is a need for sorting at early stages on conveyor belts there is a compelling basis for adopting XRF analysers.

There is no better convenience than the availability of distinctly different technologies for online geochemical elemental analysis. However, this can also be a source of confusion.

And that’s where informed choice is paramount. It is important to note the capabilities of each technology and what will best suit the intended application and type of sample material under interest.

It must be reiterated that XRF may be the end-all, be-all. Thus, the following are basic aspects of the other technologies worth grasping: Both near-infrared (NIR) and laserinduced fluorescence (LIF) emit energy to the surface of the material.

The characteristics of the material are analysed based on how the energy is reflected.

PGNAA produces high-energy gamma rays from the sample material.

It requires a high-energy source of neutrons for the analysis. The drawback is that it uses radioactive sources and thus, a source of health and safety risks. PGNNA has established a fertile niche in cement production applications.

One of the latest BSI developments is a mobile facility for gold ores gammaactivation analysis.

It can be easily attached to a flow-line at digging locations and mines, and has proved itself reliable in the following applications: 1. Analysis of iron ore and concentrates 2. Analysis of iron (as a trace element) in sand 3. Analysis of chromite ore and concentrates 4. Analysis of copper ore and its concentrates 5. Analysis of zinc ores 6.

Quantitative analysis of uranium and its production waste 15. Analysis of phosphatic materials 16. Analysis of thorium

Gamma-activation analysis (GAA) is a method uniquely suited to the analysis of ore samples for gold, other precious metals and complementary elements. It is based on the irradiation of ore samples with high energy gamma quanta generated by a linear accelerator and detection of the induced activity of the excited gold nuclei by a gamma spectrometer.

The high penetrating power of gamma radiation facilitates the analysis of large samples, eliminating the need to crush and grind the sample, while offering the following advantages over conventional methods: • A significant increase in the accuracy of the analysis representation; • Reduced analysis time due to the short half-life of excited gold nuclei: just 20-30 secs; • Sufficient analysis sensitivity, accuracy, selectivity, representativeness and productivity required for modern gold mines.

For gold ore content up to 1 ppm, measurement deviation of 8% or below, while ore content with up to 10 ppm comes with a deviation of 4% or below; • Consistent analysis results regardless of chemical composition of the sample; • No negative impact on the environment: the induced activity of the sample decreases to background levels several minutes after analysis is concluded; • Non-destructive processing of ore samples, allowing repeated analysis of ore sample; • The method allows multi-element analysis over the course of a single cycle and measurements; • ability to automate the GAA analysis; and

Europe Theta/Theta Benchtop X-Ray Diffractometer

Today's industrial applications are less and less compatible with the time it takes, for example, to send a sample to a central laboratory and wait for its response. A decidedly uneconomic approach considering that in many sectors such as mining, production sites are located in remote areas.

GNR's challenge is therefore to provide customers with instrumentation that can guarantee the same accuracy and accuracy that can be achieved in the laboratory and can be used by not necessarily qualified personnel. Two different analytical techniques are herein after presented as example of GNR capability to develop instrument for industrial application.

X-ray Diffraction (XRD) provides rapid identification of particulate materials, clays and other minerals offering detailed information about the crystallographic structure of mineral samples to be used to identify the different phases present.

In the past, XRD was typically used to determine bulk mineral assemblages in rocks, clays, ores, particulates and metallurgical products. It provides a semi-quantitative method for determining the normative or weight percentages of the phases present, including the fraction of each mineral phase that occurs in your samples.

Now, with the use of Rietveld (RIR analysis) quantification methods and powerful computers, quantitative XRD data can be obtained. Modern high-speed detectors allow rapid data collection on large numbers of samples and whole pattern cluster analysis is used to differentiate sample populations.

RDE-OES Total Cost of ownership (TCO) is a method of economic assessment widely used by many companies in the mining sector.

However, the contribution and the importance of monitoring of the quality of lubricants during the exercise is often not properly considered.

A proper assessment can result in significant savings in terms of lubricant usage, maintenance costs, reduced equipment downtime and resulting in increased plant productivity.

It is generally established that a relevant portion of maintenance expenditures in the mining field relate to the cost of lubricants Measurement of Wear metals, contaminants and additives in lubricants oils and coolants it is one of the main diagnostic methods considered within preventive maintenance programs such as Oil Condition Monitoring (OCM) Equipment Condition Monitoring (ECM) and Condition Based Maintenance (CBM).

A regular evaluation program can avoid problems of sudden breakdowns of mechanical components such as gears, bearings, turbines, allowing you to assess the machine downtime and maintenance on time.

The ability to assess both the type of element and its concentration can give valuable information to identify the mechanical component in distress.

Determining certain elements used as wear additives, dispersants and detergents can give indications on the qualities of the lubricant and its residual life.

T

he Wits Mining Institute (WMI) at the University of the Witwatersrand in Johannesburg will be hosting two exciting courses in July 2022 with well-known excavation, load and haul expert Professor Zvi Borowitsh. The first course – on Mechanised Earthmoving in Mining: Equipment, Technology and Management – will run from 27 to 29 July, while the second course will focus on Maintenance Management in Mining and be held from 13 to 15 July.

The courses will be conducted online using remote learning platforms which enable interaction with the lecturer and among participants; these platforms will also facilitate group discussions on case studies. Professor Borowitsh, who is attached to both the University of the Witwatersrand and the Israel Institute of Technology, specialises in earth and rock excavation, as well as load and haul optimisation. He has extensive academic

The course on Maintenance Management in Mining recognises that 30-60% of direct operating costs in a mechanised mine will relate to equipment – making the performance and maintenance of this equipment vital to success. The content will come from university and industrybased lecturers, and the three-day online course will comprise a mixture of lectures and case studies. Contact time will be supplemented with homework reading and a study pack.

Among the topics to be covered are: the strategic management of mining equipment maintenance; realtime monitoring of machines; data interpretation; machine application and component wear; optimising component life; and data links for supporting maintenance. The course will also explore oil sampling for detecting component wear, the principles of outsource service agreements, optimising parts inventories, basic workshop and field service planning, and safety in mine maintenance.

LAY-FLAT

HOSES SUPERMAN HVT

M

andals lay-flat hoses are an important part of an optimal water management system. Effective mine de-watering and slope depressurization systems are important components of many surface and underground mining operations.

In high flow and deep well de-watering systems for mines, layflat hoses are used to deliver or remove the many thousand gallons of water needed per minute. In mines where pit slope depressurization is essential to maintain stable slopes, lay-flat hoses offer ease of handling, deployment and retrieval. And if the mining operation is to be taken to a deeper level, bore hoses are used to remove ground water.

Lay-flat hoses are ideal for rapid large volume de-watering due to less pressure drop over large distances. Not to forget the rapid and flexible deployment compared to other types of rigid hoses or steel pipes.

Mine de-watering takes place in the harshest of environments.

This requires extremely abrasion resistant hoses to withstand being deployed down steep, rocky mountain sides, lowered into deep wells and to carry the weight of a full set of submersible pumping equipment. www.mandals.com/industries/mining

Automated system for loading management in mining industry Digitalization of real-world in more intelligent and efficient loading processes Bulkmeter has an auditing system that allows reviewing the results of every measurement in detail, such as 3D images of the truck, images of the load, vehicles ID, loading reports, among others.

P

rocess management becomes critical when it comes to increase productivity and profit through operational efficiency. In Woodtech we developed Bulkmeter, an automatic system that obtains in real time reliable and accurate information of raw material truckloads, allowing operators to take timely corrective actions in the loading process.

Among its main contributions to the mining industry, Bulkmeter allows for consistent traceability of raw material movements from the mine to the crusher and real-time warnings, which help to achieve a better productivity. Its state-of-the-art laser technology allows the user to identify in real-time oversized rocks on the loading surface of the truck and reduce the risk of damaging the crushing machines. The

reporting system of Bulkmeter delivers valuable information such as loading distribution reports, which offer relevant operational insights to optimize the loads in each trip, avoiding over or under loaded trucks. Also, the system allows for comprehensive inventory control, among other benefits.

“We are a technological company, specialists in industrial processes.

This expertise enables us to develop solutions that can show key operational administration data to create efficiency.

Bulkmeter requires minimal intervention in current operational environment and easily integrates into existing customers systems, for example, ERPs. This is widely appreciated by our clients.” said Carlos Bussinger. CEO of Woodtech.

Bulkmeter benefits • Information of all incoming and outgoing trucks to the plant • Auditable evidence for 100% of incoming and outgoing trucks • Accurate volume measurement for each truckload • Less time needed for truck inspections • Oversized rocks detection and realtime warnings Successful case Recently, Woodtech developed a new solution for one of its biggest mining clients in Brazil. It is based in is a control system that allows measuring the volume of material removed over a large area. 9 #Bulkmeters are organized in 4 control points arranged in a wide area.

In real-time, this system could perform up to 12,900 dump trucks’ closed-loop measurements every day.

“We are very glad, because we could respond to the need of accurate and traceable information”, said CEO of Woodtech.
