Following the recent appointment of Cyril Ramaphosa as president of the country, the belief is that he is particularly well suited to deal with issues in mining because of his history with the National Union of Mineworkers (NUM) and his understanding of the industry.

As such, it is not all bad news and things are certainly looking up for the rest of Africa too, as Warren Beech, mining partner at Hogan Lovells, details in this issue’s legislation article on page 16. In this issue, we also have specialised industry insight from Standard Bank, discussing – from an economic perspective – renewed industry and market optimism.

Responsible mining has become increasingly topical, with a number of sessions at the Mining Indaba having focused on the importance of getting the ore out of the ground in a sustainable and responsible manner. The Initiative for Responsible Mining Assurance and the London Bullion Market

The recent diamond finds that have come out of diamondrich, landlocked Lesotho have excited the market. Out of Letšeng Diamond Mine came the fifth largest gem-quality diamond ever found earlier this year; a few kilometres away, Mothae has started to produce quality diamonds just a few weeks into production.

which, at the time, projected a fouryear life of mine to 2014.

However, continuous innovation ensured that the mine has continued to operate well beyond this time, with a current life of mine extending to 2019.

Following a recent review, it was concluded that the best way to secure a longer future for the mine, beyond the current projected 2019, is to find a more suitable low-cost operator that could allow the mine to continue to contribute to Namibia and Lüderitz through continued employment and economic activities.

Make South Africa

attractive again

The Investing in African Mining Indaba is always a muchanticipated conference. What is your analysis of this year’s Indaba?

How do you see the industry outlook for 2018 and are we going to see rapid growth?

WB This year’s Mining Indaba has been slightly different to those of the last few years. Last year, the mining companies were talking up their projects and saying there’s a recovery, which there wasn’t really. There was a lot of optimism, probably reckless optimism in some cases.

Right now, I think, although not necessarily in South Africa, there is positivity across the continent, seen in the growth and projects coming from the countries that are really looking at mining as a catalyst for their growth and development, like Uganda, Nigeria and so on.

That is really exciting.

At Indaba, Inside Mining sat down with Warren Beech, global head: Mining Subsector at Hogan Lovells, to discuss his view on this year’s event and the mining industry as a whole.

For now, it is safe to say that South Africa is excluded from the excitement; unfortunately, Minister Zwane’s speech was underwhelming. He had an opportunity and platform to send out a positive message of change, and he failed to do so.

So, I think that really put a damper on the outlook for South Africa.

Which area in Africa has the Hogan Lovells Mining Division identified as a key growth area?

As a company, our focus is still very much on South Africa, because we see that the bigger companies are still putting in money and there are new projects coming in. It is exciting to see companies like Rio Tinto recommitting.

But on the topic of rapid growth, our countries of interest at the moment include Namibia, which is really picking up, and Zimbabwe – the big story of

“South Africans really are entrepreneurs and inventors on every level. We know how to work in very difficult environments, and a lot of the technologies we have developed for the industry in the past have been exported.”

Speaking of politics, what are the kind of expectations placed on President Cyril Ramaphosa, given his background in both business and unions?

There is an incredible burden on him because he’s taken on the role of change.

He’s going to be pulled by both sides: business will expect him to understand business and the trade union movements will expect him to deliver because he is president. He will need as much support as he can get.

Do you think technology will be vital for the mining industry in the future? Will South Africa have to take the lead in technological advancements in mining in order to be competitive on the continent?

positioned as an investor-focused conference; however, I think the junior mining talks do include the unions, which is a critical part of these conferences and rightfully so. The trade unions need to be included more often in the mainstream discussions too.

Uncertainty appears to be an issue in the mining industry, such as with the Mining Charter.

How will uncertainty within the mining sector affect the kind of confidence needed to achieve growth?

Policy uncertainly is a major concern, because policy transcends everything.

If policy is in place, then you understand it for what it is and adjust to it.

The cast steel or manganese flights are designed to overlap so as to reduce spillage. The machines are constructed using traditional D4, D6, D7, D8 and D9 track components.

Osborn has, over many decades in business, developed a formula to determine the ideal-size apron feeder for a customer’s requirements. “Factors like flights and chain type, start-up and running torque, chain factor of safety, start-up conditions, and running conditions are all considered in the calculation. For drive sizing, we calculate breakaway torque, running torque, absorbed power, installed power, head shaft speed, and chain pull. Our vast experience and expertise ensure that end users get the best machine and optimal performance,” Botha concludes.

The customised LTP-B Eco Drive for pump and fan control in a range of niche sectors from HVAC to underground mining will also be showcased at bauma. Maleka says this approach was inspired by the demand in the market for a product of this nature.

“We have had several requests for HVAC products and, at the time, we did not have a product able to meet this specific demand. We had a general purpose drive that could do it, but with limitations. As demand grew, we decided to pursue this new avenue, to design a dedicated product to serve this market, especially in Cape Town

Business Integrity Operating companies conduct their business in a transparent manner that complies with applicable host country and international laws, regulations and best practice, and builds trust and credibility with stakeholders.

Planning and Managing for Positive Legacies Operating companies engage with stakeholders to ensure that mining projects are planned and managed to deliver positive economic, social and environmental legacies for companies, workers and communities.

Social Responsibility Operating companies engage with stakeholders and rights holders to ensure that mining occurs in a manner that respects human rights and maintains or enhances the health, safety, cultural values, quality of life and livelihoods of workers and communities.

Environmental Responsibility Operating companies engage with stakeholders to ensure that mining occurs in a manner that maintains or enhances environmental values, and avoids or minimises impacts on the environment and communities.

The SRM measures achievements across a broad range of social and environmental issues, including: labour rights, and health and safety; emergency response; cyanide and mercury management; biodiversity, ecosystem services and protected areas; free, prior and informed consent; cultural heritage; security arrangements; human rights; conflict zones; tailings management; water, waste and air quality management; community health, engagement and benefits; revenue transparency; reclamation, closure and bonding; and reducing greenhouse gas emissions.

LBMA engagement at Indaba “Our major purpose for coming to the Mining Indaba has been to engage with people about responsible sourcing.

So far, it’s been really successful – I think people are really interested now. When we first launched our programme in 2012, there was a fair amount of resistance in the industry – people were worried about how this was going to disrupt the market. Now, however, people are starting to think about reputational risk.” Ruth Crowell, CEO, LBMA

So, if we can find a way to streamline this, then it makes it easier for the refiner or producer to manage it. It also means that, in the end, you have the DNA of that material. In terms of how you translate that to the consumer, it makes the entire supply chain and the product that much more ‘real’.

About Ncamiso Mining • Ncamiso specialises in maximising the revenue of its clients by screening gold from material that would otherwise be sterilised and crushed for roads and buildings, etc. Ncamiso also provides a valuable service through the removal of contaminated surface material to rehabilitate the ground as well as services in open-pit mining and screening and crushing.

• Ncamiso consistently works towards the merging of industries among mining, construction and farming in order to close the gap that was created by mining in the past. In each project Ncamiso takes on, the company strives towards the rehabilitation of land for residential development, the eradication of illegal miners, and job creation in local communities.

Innovative solution This water reclamation plant is the first dissolved-air flotation reclamation system used on a platinum mine to reduce potable water consumption for gland service water. The BRPM water reuse facility has been in operation for nearly 12 months. Based on actual water savings and operating cost savings, the capital invested is projected to be paid back in under four years.

What is even more remarkable is the fact that potable water use was reduced by 50%. Some of this water will be used for future production expansion and it could also be used for expanding potable water supply to neighbouring communities.

The BRPM case study demonstrates that, with a proper understanding of mine water circuits, many water reuse opportunities exist and that water reuse is not only an imperative from a water resource perspective, but also from financial and socio-economic perspectives. Ultimately, the water security of the mine has improved significantly, with the associated benefits in lower water input costs as well as lower probability of production stoppages due to water shortage.

from around the continent Great quality, great service The SKF Explorer series large-size roller bearings have presented the optimum solution for a vertical roller mill used in the production of cement.

This translates to improved

Reliable and durable wireless connectivity IT and automation technology are maintaining and improving productivity in the mining industry, and mining companies have already introduced remote-controlled machinery to their fleets, with monitoring equipment performing regular checks on the health status of this equipment.

One such company, MiRO, a local distributor for Radwin solutions, believes that the mining space will increasingly benefit from the deployment of Radwin’s PtP (Point-to-Point) and PtMP (Point-to-Multipoint) technology.

According to MiRO, there are various deployment scenarios, dependent on whether the solution is defined as a nomadic or mobility option, as well as whether it will be used above or below the ground.

“We recommend using the Radwin FiberinMotion, with a range in excess of

Radwin JET subscriber unit

10 km, for mobility applications and the Radwin JET smart beamforming PtMP for nomadic and PtMP applications, for distances of up to 40 km,” says Marco de Ru, CTO at MiRO. “One of the big differentiators for these solutions is that they are able to seamlessly perform handover between sectors with ultralow latency and jitter, combined with high capacity throughput of up to 250 Mbps per subscriber for the mobility applications.”

The unique air interface of the Radwin JET beamforming solution provides robust and stable performance even in the harshest spectrum conditions.

Mutual interference between sectors and sites is eliminated by the integrated GPS synchronisation feature, which ensures linear capacity growth even when users add more radio units.

Cummins launches simulator

Cummins Power Generation has launched a new simulator at the Cummins Training Centre in Kelvin, Johannesburg, to demonstrate its entire product line-up as an integrated solutions approach, from genset controls to annunciators, remote monitoring, Digital MasterControl (DMC) and transfer switches.

The PowerCommand Control Panel was showcased at the launch. It is an autonomous microprocessor-based control for paralleling, load-sharing and protection.

The simulator covers the broader African market, joining a similar set-up in Dubai for the Middle East and North Africa, with another simulator set for Nigeria, for Central and West Africa, explains Alok Joshi, director, Cummins Africa.

“Our plan is to have these simulators located in key markets for consultants and contractors.”

DMCs come into play in complex systems such as data centres, wastewater treatment plants, and healthcare facilities. “These are all critical applications in terms of standby power. We are now able to simulate real-time scenarios, and how our products respond to those conditions,” Joshi highlights. The simulator is aimed specifically at customers in power generation that specialise in backup or prime power supply.

New technology for fire suppression Building on its established reputation in proximity detection systems (PDS), Booyco Electronics is now also offering the latest fire suppression technologies to help customers manage their health and safety risks.

“It was a natural extension of our business to move into fire suppression,” says Anton Lourens, managing director of Booyco Electronics. “Our expert PDS detection equipment is vital in detecting potential dangers around trackless mobile machinery (TMM). Now, we can also offer the latest suppression systems as part of the total solution from a single

service provider, thereby creating a better value proposition.”

Lourens emphasises that the effectiveness of fire detection and suppression systems is becoming a more urgent issue for mines, as there are new South African standards being formulated for fire detection and suppression systems on heavy-duty mining machines.

The company will be the preferred distributor for Advanced Automation Systems (AAS), which exclusively markets the DAFO brand of vehicle fire protection and FirePro aerosol-based extinguishing systems in South Africa. “We believe that AAS is a

market leader in multiple offerings that hold great value for our existing customer base in mining and related sectors,” says Lourens.

“Our long-established geographical footprint, sound reputation and strong relationships in the market will, in turn, offer great opportunities for AAS to grow its impact.”

Chillers and heat pumps for mid-capacity segment Johnson Controls is launching its Amichi Series of chillers and heat pumps into the South African market. With capacities of 45 kW up to 260 kW, it’s the perfect fit for the local mid-capacity segment, combining the price benefit of a scroll chiller with the increased control a direct current (DC) inverter offers.

“The new York Amichi Series Air Cooled Scroll DC Inverter Chillers (YMAA model) and Heat Pumps (YMPA model) are being launched locally and in Europe to meet growing demand in the chiller/heat pump mid-capacity segment.

“With high levels of efficiency and performance and the smallest footprint across the widest capacity range on the market, this series will provide an excellent fit as a solution for new builds, technology refreshes and retrofits in manufacturing and

commercial facilities,” says Neil Cameron, general manager: Building Efficiency Africa, Johnson Controls.

According to Cameron, the Amichi range meets or exceeds the requirements for the Ecodesign regulations for heat pumps, comfort chillers and process chillers through an optimised combination of York efficiency-enhancing technologies.

He says the YMAA leads the scroll and screw market in part-load efficiency and the YMAA/YMPA get the best sound performance in the market with no efficiency compromise.

“The series comes standard with integrated smart equipment technology that allows the equipment to connect seamlessly to a building control systems where smart-enabled equipment self-identify and

interoperate,” says Cameron. “It provides a truly plug-and-play experience, with no need for programming or commissioning tools.

“For added flexibility, it comes standard with BACnet, Modbus or N2 communication protocols to communicate with any BMS. In addition, an Optiview LT 7-inch colour touchscreen is fitted on the unit frame, with the additional option of a remote indoor controller accessory,” he concludes.
