Assuring the local people about the creation of jobs, Minister Kabba said that government will ensure that local content is guaranteed. “We must make efforts to empower ourselves,” Minister Kabba said, urging Kingho Mining Company Limited to think about technical vocational training for Sierra Leoneans in the mining areas, as well as to get them onboard in contributing to much needed activities of the mines. Minister Kabba assured of government’s fullest commitment to Kingho achieving its objectives, and called on all across every divide to collaborate in ensuring that the Tonkolili Mining Project sets a very good precedent for future mining projects across the country. CEO of Kingho Investment Company Limited – Gilbert Zhao said the takeover ceremony is a new dawn for the people of Sierra Leone. He added that as a company Kingho “has been working with the Government of Sierra Leone and Government of China over the last several months trying to have a smooth transition leading to a peaceful and orderly takeover of the mine and its associated assets.” In addition, the CEO of Kingho Investment Company Limited assured that “in the next few days, we will start full scale maintenance work on the mining, processing facilities and accommodation quarters which will provide several jobs for skilled and unskilled Sierra Leoneans. We will definitely seek for continuous improvement in all aspects of the mine and operations.” “In line with the Government’s local content policy and other key government regulations, we have recruited and in the process of recruiting qualified Sierra Leoneans that will hopefully add value to the organization and bring this project to fruition. We will transform the labor market by empowering citizens at local and national level. We believe that the human resources are our greatest assets,” Mr Zhao confirmed. The Kingho head concluded by thanking the Government of

Sierra Leone through its ministries, departments and agencies for the confidence reposed on Kingho Mining Company Limited. He said “we will also want to thank the community elders, all stakeholders and citizens of this Republic for their support in ensuring that the new Tonkolili Iron ore project gets the required attention and prime mover it deserves.” From the side of the executive arm of government, whilst dilating on the commitment of President Julius Maada Bio in empowering young people across the country, the Honourable Minister of Youth Affairs, Mohamed Orman Bangura said that government views transparency as the hallmark of the New Direction. He spoke about Kingho’s previous commitment to social corporate responsibility. He spoke about what the people of Tonkolili would gain should they collaborate with Kingho in achieving its mining objectives. Leader of Government Business in the Sierra Leone Houses of Parliament, Honorable Sahr Matthew Nyuma who was also present said: “We are here to serve as living testament to the people.” He reaffirmed that parliament would ensure that honouring locals will be central to Kingho’s investments and employment. He called on youths to engage in dialogue instead of violence and called on them to be involved in sensitive and positive engagement. In addition, the Parliamentary Committee Chairman on Mines and Mineral Resources Honourable Saa Emerson Lamina who was also present at the handing over ceremony, said “government will not create all jobs, but will create credible investment that will create jobs for the people of Sierra Leone.” He said, as MPs, they were present to give assurances to the people, the government and the investors. He called for peace, unity and solidarity of purpose from stakeholders and the people of Tonkolili District. He assured that as a parliamentary committee, they will work in ensuring that Kingho honours its obligation and achieve its mandates.

Top 10 Gold Producing Countries By Frank Holmes, CEO and CIO, U.S. Global Investors Gold is one of the rarest elements in the world, making up roughly 0.003 parts per million of the earth’s crust. But how much gold is the world digging up each year and what countries produce the most? In 2019, global gold mine production was a reported 3,463.7 tonnes – down one percent from the year prior – and the first year-over-year decline in output since 2008. Gold production has remained relatively steady since 2010, raising the question I’ve explored over the years – have we reached peak gold? The idea is that all the easy gold has already been discovered and explorers have to dig deeper to find economically viable deposits. For example, South Africa was once the top gold-producing country by far, digging up over 1,000 tonnes in 1970, but annual output has fallen steadily since. On the other hand, several nations have emerged in the last few years as growing gold producers. As seen in the chart below, China takes the number one spot of global gold producers by a wide margin. The top 10

10

rankings saw a big shift in 2019 – Russia took the lead over Australia to claim second, Indonesia fell off the list and Brazil joined the ranks as the tenth largest producer. Ghana also jumped ahead of South Africa to become the continent’s top producer. Below are more details on the top 10 countries with the largest gold production in 2019, beginning with the top producer and top consumer of bullion, China. All data is from the World Gold Council. 1. China – 383.2 tonnes For many years, China has been the top producing nation, accounting for 11 percent of global mine production. However, production fell from nearly 400 tonnes last year, representing the third consecutive year of declines. The downtrend is largely due to tighter environmental policies imposed by the government. For example, stricter control over the use of cyanide at gold mines forced several operations to cut back production. 2. Russia – 329.5 tonnes A massive 83 percent of European gold comes from

Russia, which has been increasing its production every year since 2010. Russia took the lead over Australia to become the world’s second largest producer – mining 50 tonnes more in 2019 than the year prior. Who is the largest buyer of Russian gold? The Russian government, of course, which purchases around twothirds of all gold produced locally. 3. Australia – 325.1 tonnes Australia has posted seven consecutive years of increases in production, up by 4 percent in 2019. The minerals industry produces over half of Australia’s total exports and generates about 8 percent of GDP. Higher production at several mines and the ramp of projects such as Mount Morgans and Cadia Valley contributed to increased production. 4. United States – 200.2 tonnes American gold output fell by 11 percent in 2019, ending five consecutive years of growth. Twelve states produced the gold, worth about $8.9 billion and accounting for 6.1 percent of the global total. Around 78 percent of gold produced in the U.S. is from Nevada.

Canada – 182.9 tonnes Canada has held the number five spot for three years now, even with a slight decrease in output in 2019. New projects in Nunavat, Yukon and Quebec are expected to support stronger output in 2020. Canada’s gold mine production is estimated to grow by a compound annual growth rate of 2.7 percent from 2019 to 2023 to reach 7.6 million ounces. 6. Peru – 143.3 tonnes Gold output fell for a fourth consecutive year in Peru largely due to crackdowns on illegal mining operations in the La Pampa region and lower grades at existing projects. Mining is a significant portion of Peru’s economy and accounts for over 28 percent of the region’s total output. 7. Ghana – 142.4 tonnes

Key pieces to Zimbabwe’s US$12bn mining industry

IN

October last year, the Zimbabwean government tabled an ambitious policy document that aims to turn the mining sector in the country into a US$12 billion industry by 2023. Achieving that export target will represent a 275% jump from the US$3,2 billion realised through exporting mining commodities in 2018. The blue print targets gold output of US$4 billion per year with platinum coming in second at US$3 billion. Diamond is targeted to grow to US$1 billion, equal to the combined target of chrome, nickel and steel. Coal, hydrocarbons, lithium and other minerals are projected to contribute the remainder.

Zimbabwe’s mainstay in the foreseeable future, thanks to the massive investments made in value-addition and consistent reporting standards implemented by the current PGM miners. In the same period, diamonds contributed 5,71%, while nickel and black granite contributed 1,72% and 0,84% respectively. The mining sector has over 800 operating mines across the country and these range from international mining houses to small-scale mines. In terms of employment, over 80 000 workers are employed directly and indirectly in downstream businesses. The sector is also home to over 550 000 smallscale and artisanal miners who are mainly engaged in gold and chrome mining.

In 2019, export earnings from mining plunged 9% (to US$2,91 billion) as a result of crippling power cuts, foreign currency shortages, increase in operating costs and smuggling of gold in protest to the low foreign currency retention scheme of 55% which prevailed then.

Economic suffering has contributed significantly to the surge in the number of artisanal miners in the past two years in areas such as Gwanda, Zvishavane, Shurugwi, Kwekwe, Mazowe, Chinhoyi, Bindura and Chegutu, among others.

Platinum Group of Metals (PGMs) contributed 43% of the of the mineral export receipts last year, surpassing gold which contributed 38%. Platinum is likely to be

reserves in chrome, gold, nickel, diamond, iron ore and platinum. The country has a massive competitive advantage in the mining sector with a highly diversified mineral resource base of over 40 commercially exploitable minerals. Investment figures and enquiries are heavily biased towards mining, highlighting the importance of the sector to the country’s growth prospects in the long-term. The Chamber of Mines in Zimbabwe (CoMZ) recently predicted that production from mining could reach US$18 billion by 2030 if key challenges in the sector are ironed out through policy and legislative reforms. The following are some of the key pieces that need to be fixed in order to attain the government’s US$12 billion target in three years’ time. Transparency and corruption The biggest impediment to the attainment of Zimbabwe’s mining target is lack of transparency and systemic corruption in the sector. There is massive red tape and bureaucracy in the processing of mining certificates, verification of applications, ground inspection and

Mining

awarding of Exploration Prospecting Orders (EPOs). Added to it, there is disregard for rule of law by those politically-connected and delays in the settlement of legal disputes. For a long time, diamond mining remains a murky affair due to the involvement of a number of controversial mining houses, controversial investors and the army. The impact of corruption is that the country loses millions in potential tax proceeds while billions are externalised out of the country through illicit financial flows (IFFs). Communities that should benefit from mining activities are left marginalised with poor infrastructure and environmental scars. To address this, Zimbabwe needs to join the Extractive Industries Transparency Initiative (EITI) and implement its global standards on accessibility of mining data and transparency of operations. Joining EITI ensures that the government commits to full disclosure of information on beneficial owners of mining claims, claims size and number of minerals assets, minerals output, revenues, tax contributions and other information pertaining to minerals marketing. Mining legislation The Mines and Minerals Amendment Bill of 2015 has been stuck in parliament for close to five years now. The Bill was introduced to amend and reinforce the archaic Mines and Minerals Act of 1963 which is currently being used locally. The current mining law lacks on provisions that plug mineral revenue leakages and tax evasion, and consolidate tax payments by miners. More importantly, the law promotes opaqueness in licencing, corruption by state institutions that oversee mining and secretive side marketing of precious minerals. The new Bill should also decriminalise and formalise small-scale and artisanal mining to ensure proper reporting, private sector financing, taxation, minimum safety standards, inspections and environmental management.

The amendments to the current mining legislation should be expedited as they are key in ramping up production and increasing transparency in the industry. Gold stats: Smuggling of gold In 2019, the Treasury department admitted that only 33% of gold produced in the country is delivered to the central bank. The bulk of the gold worth close to US$2 billion is lost through smuggling cartels that have influence in the entire value chain from owning gold mining claims (which are mined by artisanal miners through gold-sharing arrangements) to owning gold-buying licences to illegally exporting the mineral to South Africa and United Arab Emirates (UAE), among other countries. Parallel market buyers also pay cash to small-scale miners, taking advantage of the central bank delays in paying for delivered gold. It has been alleged that large-scale producers have also been under-declaring their output, while selling their gold via small-scale producers to get 100% foreign currency. This means that the country loses millions of dollars in taxes on foreign currency earnings. To curb smuggling, the central bank needs to ensure that the foreign exchange market freely floats to preserve value for exporters on the surrendered export portion. Alternatively, it can allow miners to retain 100% of their export earnings in a scheme which would see all export proceeds being repatriated back to Zimbabwe. Investment in exploration New investment in the mining sector is hampered by lack of information on the size and quantum of mineral reserves. Similarly, there are limited incentives to current miners who invest in exploration. So far there has been no investment in the exploration of recently discovered Rare Earth Elements (REEs) minerals despite huge global demand for the minerals. To identify new mining areas and fully exploit the abundant mineral resources, the

www.subsaharamining.com | October-December 2020

government needs to set aside a fund for exploration (through the Geological Survey Unit) from collected mining royalties and to grant as many timebound Exclusive Prospecting Orders (EPOs) as possible. Incentives to value-addition A significant portion of mining commodities exported from Zimbabwe are shipped in their raw or semi-processed form for further value-addition in other countries. The government took a deliberate effort in incentivising beneficiation of platinum locally and the policy is gradually bearing fruit. Tax incentives should be offered to current or new miners on additional investment made towards value-addition of lithium, REEs, gold, diamonds, nickel and chrome. Value-addition locally creates downstream employment, fosters transparency, increases mining output and tax proceeds payable to Treasury from the entire value chain. The recent changes on the indigenisation and empowerment legislation to allow for over 51% foreign ownership of mining assets (except for platinum and platinum assets), has also improved foreign appetite for investment into the country. So far the mining sector is beset by perennial challenges that hinder investment, optimum production and access to offshore loans. It will be mission impossible to attain the set output targets without changes to the current mining legislation and policies to guarantee transparency and investment in mineral exploration. Above all, strong institutions such as implementation of EITI, respect for rule of law and property rights are overdue in curbing systemic corruption and opaque operations in the mining sector. If the government dares to dream of a US$12 billion mining sector, it should also dare to reform its mining laws and policies that are hindering optimal production from the billion-dollar mining industry.

Africa: Mineral Wealth Gives Africa Key Role in New Global Economy Throughout the world, resource wealth is an emotive and politically contentious issue. But genuine partnership between international industry and African governments can provide a major boost to the global economy. Citizens of resource-rich countries are demanding greater social and economic benefits from their natural resource endowments, and governments have moved to exert increased control of resource rents – for national benefit or, in the worst cases, personal enrichment. In Africa, these tensions are exacerbated by the vestiges of colonialism and narratives of exploitation, legacies of prior waves of nationalization – and now the devastating impact of the COVID-19 pandemic on societies and economies across the continent. For international mining companies and investors, ‘African agency’ is often synonymous with state intervention, resource nationalism, and risk amid unquestionable opportunity.

16

To change this perception, and to support a rejuvenation of the industry across the continent, there is an urgent need for open and collaborative dialogue between government and industry that goes beyond revenue management. Only by working together can the government and industry create a well-managed and sustainable resource sector that continues to work as a force for the development of Africa. Regulation and impact Mining remains a significant source of foreign direct investment (FDI) for Africa, as new mining projects brought in US$18 billion in investment across the continent between 2015 and 2018, and a further US$10.5 billion is planned. Automation and new technology makes mining less labour-intensive but jobs are now safer and higher paid, while localized supply chains are increasing opportunities – a trend likely to be accelerated by COVID-19, along with industry attention

and ‘local content’ policies in many African states. Most African mining jurisdictions already have in place some form of local ownership requirement, with international mining houses sharing ownership at levels from 30-51% or sometimes more with local partners. But well-intended regulations and tax regimes, restrictive local content, or empowerment criteria can have the unintended consequence of stifling investment and diminishing long-term positive impacts from the industry. Over the past five years alone there have been regulatory changes, such as mining codes and tax regimes, across the continent, especially in the major mining economies of South Africa, Namibia, Botswana, Zambia, the Democratic Republic of Congo and Tanzania. In many cases, this has put industry and government on opposing sides and fuelled perceptions of investment risk, even when

seeking the same developmental outcomes. This is because complex tax regimes struggle to deliver on developmental objectives. In South Africa, companies pay taxes at a national level, royalties at a regional level, and pay into local community trusts. But a survey of one mining community found 79% of community members felt no benefit from the industry. Many countries have also legislated local and national procurement requirements, with up to 80% of procurement spend required to stay incountry. This creates two challenges: firstly, because mining projects are usually built in rural and remote areas, there is limited local capability to fulfil the operation’s needs; and secondly, once developed, local supply chains often remain dependent on a mining operation with a limited life.

Industry can certainly improve the coordination efforts and do more to recognise local decision-making processes and accountability mechanisms. However, this is only one side of the coin – corporate accountability must go hand-in-hand with government accountability. In most places in Africa, the majority of the cashflow from mining stays in-country with only dividends taken overseas. But in too many instances there is little to show for the revenues generated, and local ownership often provides little material benefit for local communities. The debate on spending royalties often focuses on infrastructure without taking into account the need for critical enablers – doctors and nurses in medical facilities, teachers in schools, or coaches on sports fields – or the importance of avoiding duplication.

However, revenues can be used to mitigate these challenges – creating opportunity for businesses, industry and supply chains not just linked to the resources industry, but also attuned to the needs of the wider community and regional market. This creates the foundation for truly sustainable development.

Governments can also do more to understand modern mining and explain to citizens the risk the industry accepts when investing and entering into partnerships. There is no substitute for dialogue and coordination to maximize value from the expanded economic opportunities the industry can generate.

Decision-making and delivering value Mining is often seen as a ‘zerosum’ competition between citizens and international mining companies, so bridging this gap requires a new collaborative approach to creating value. Conversations around host country agency, and control over resource revenues, do not need to be confrontational.

Companies, governments and communities have a shared responsibility to manage natural resources in a sustainable and mutually beneficial way. License to operate is not a just a compliance exercise, but an ongoing relationship, and a partnership between an international company and its host country extends beyond paying taxes and royalties.

National governments control access to the resource, but often lack the capital and know-how to exploit it in an efficient, profitable and sustainable manner. International mining companies bring with them the skills and resources for extraction – but can only do so in partnership with host government and citizens, securing regulatory and social license to operate.

Nationally-defined mechanisms for distributing revenues, through taxes, or procurement and ownership legislation, must broaden the space for citizen participation beyond a narrow elite and ensure decision-makers are accountable to wider society. Empowering agency Talent is also both a major challenge and opportunity, as few Africans are employed in the international private

www.subsaharamining.com | October-December 2020

sector, especially in senior management and decisionmaking positions. There is still a ‘glass ceiling’ for Africans with misperceptions and bias exacerbated by disparities in the quality of local and international education systems. This can result in a pay gap between expatriates, or returning diaspora, and local staff despite local employees often having a better and more realistic understanding of the local context, community needs, and how companies can navigate them. Conversely, African staff have historically not been afforded opportunities to gain experience and knowledge by working in other parts of the world, thereby limiting their opportunities for building experience and career progression. Corporate ‘inclusion and diversity’ strategies must be about more than just jobs – African perspectives and ways of doing things should be embedded into operating practices. Skills transfers go both ways and international businesses need to be prepared to absorb best practice learned on the continent into international operations, from health and safety innovations through to corporate and community relations. Companies must give Africans a voice not just in their local operations, but also at a global level. There must be clear recognition that host communities and governments in Africa are not seeking largess, but instead desire sustainable development on the back of mineral wealth – creating economies to be major future customers and markets for the industry. Governments and industry stakeholders have a mutual responsibility to ensure the contribution of Africa to the global economy is both recognized and heard. Only an equal commitment on both sides can create the trust required for genuine partnership.

increasing by 11.3% year-onyear in July. This was driven in part by a 40.9% increase in sales of “other non-metallic minerals,” suggesting that a decline in mineral production does not necessarily lead to a decline in sales, and therefore does not pose a risk to the entire mining supply chain at large.

WCP B Move Update: Dredge Relocated Safely to Pilivili Kenmare Resources plc’s minin g plant has been safely transported from its previous mining area at Namalope to Pilivili, a new high-grade ore zone at the Moma Mine, in Mozambique. The transport consisted of a Wet Concentrator Plant (known as WCP B) and its dredge. It is the heaviest piece of mining equipment to be moved in Africa, to date. With 290 axles required to lift and transport the WCP B-unit, the move also represented the most SPMT axles used in Africa to date and one of the largest moves of a single piece of mining equipment in the world. Mammoet has extensive experience in moving entire plants for major industries. This expertise, combined with the capacity and capability to carry out such operations, worldwide, ensured the project was safely and efficiently executed. Having considered numerous options, it was chosen to move these assets intact and by road, as this was the lowestrisk option and limited the time out of production. Disassembling and reassembling the plant would have taken significantly longer and transporting the plant by sea barge may well have

resulted in substantial delays as a significant period of forecasted calm seas would be needed for this option. Mammoet engineers were able to provide a safe and effective solution to load, move and unload the plant in one piece. First, the plant was floated into an excavated starter pond and placed on constructed concrete plinths. The pond was then drained, allowing 290 axle lines of SPMTs (in 5 x 58 configuration) to be positioned underneath the plant, before it was moved along a 23km long, purposebuilt road with a weightbearing capacity of 8.4 t/m2, to its new location. In Pilivili, the operation was completed in reverse: the plant was positioned on top of concrete plinths and then pond around it was flooded, which allowed the plant and the dredge to float to their new mining position. WCP B weighs approximately 7,100 tonnes, including ballast, and measures 80 meters long, 60 meters wide and 24 meters high. The move was particularly unusual due to the combination of the weight of the load and the length of the distance traveled.

Kenmare Resources plc, said: “Moving the plant in one piece, an object weighing the equivalent of 550 doubledecker buses, taller than a seven-story building and wider than a football pitch, is a huge achievement for our company.” “This type of relocation is rare in the mining industry, but it was the clear choice for Kenmare given the economic benefits and lower risk profile it provided, compared to the alternatives we considered. I would like to extend my congratulations and thanks to the Kenmare team on site and our specialist contractors for completing this recordbreaking task safely and overcoming many challenges as a result of COVID-19.” Heavy mineral concentrate production from WCP B at Pilivili is expected to begin in mid-Q4 2020. The relocation of WCP B and its dredge form the third and final project of Kenmare’s development program to increase Moma’s ilmenite production to 1.2 million tonnes (plus co-products) on a sustainable basis from 2021.

Zambia royalty spat halts $2 billion of copper mine projects Copper miners in Zambia have halted $2 billion of planned investments because a royalty tax introduced last year makes the projects unviable, according to an industry lobby group.

A plan by First Quantum Minerals Ltd. to invest $1 billion extending the life of its Kansanshi operation won’t proceed until the royalty is deductible from other corporate taxes, said Sokwani Chilembo, chief executive officer of the Zambia Chamber of Mines. The same goes for EMR Capital-backed Lubambe Copper Mine’s project to invest a similar amount in a new mining operation, he said.

20

“We need this royalty payment regime removed for progress to begin,” Chilembo said in an interview. “If the government thinking is otherwise, good luck.”

“The concessions needed are not material compared to the benefits to Zambia.” John Gladston, a spokesman for Vancouver-based First Quantum, declined to comment. Lubambe is “actively engaged” in discussions with the Zambian government about its planned extension project in the country, CEO Nick Bowen said in an emailed response to questions.

“The extension project can deliver enormous benefits for Zambia and its people,” he said. “The concessions needed are not material compared to the benefits to Zambia.”

Zambia’s uneasy relationship with mining investors has deteriorated over the past 12 months, with the government clashing with Glencore Plc over the Switzerland-based company’s plan to mothball Mopani Copper Mines’ operations. Zambia’s increasingly aggressive stance over the nation’s key export industry may partly reflect maneuvering by President Edgar Lungu as he struggles with economic challenges ahead of next year’s elections.

Zambia's Maamba Collieries unveils state-of-the-art coal mining equipment Zambian Mines and Minerals Development Minister Richard Musukwa this weekend officially inaugurated Maamba Collieries’ (MCL's) most recent acquisition, a state-of-the-art, high technology surface miner, the company said on Saturday. MCL thus became the first mining firm in Zambia to operate this state-of-the-art surface miner, which could be used to mine in layers by using a milling drum without the need to drill and blast, MLC said in a statement.

soft rock. At the same time, the diesel tank with a capacity of 2300 litres makes it possible to operate the machine around the clock with only one stop to refuel per day, resulting in greater productivity. The surface miner technology allowed extraction of coal and other minerals without the need for drilling and blasting as hitherto – an advancement which was in line with MCL’s commitment to sustainable mining, the company said.

"MCL is no stranger to industrydefining mining equipment, being home to the legendary Bucyrus Erie 1260-W Walking Dragline, popularly known as the Zambian Queen, which held the record for the largest single mining equipment in Zambia for decades after its official commissioning in 1971." This time around, MCL had chosen precision and modern technology over brute force, with the surface miner ensuring optimal efficiency while mining coal.

MCL operates Zambia’s largest coal mining concession mines, both high-grade coal which meets the demand of the domestic construction sector and thermal-grade coal used in its thermal power plant to generate electricity. Speaking during the launch, Musukwa said MCL was Zambia's largest independent power producer (IPP) and the second largest source of electricity generation in the country. Therefore, investments such as this made by Maamba Collieries should be supported by all key stakeholders.

The high-tech equipment boasts a 3.8 m drum optimised for maximum productivity at minimum cost over Maamba’s

"I implore our colleagues, especially Zesco and the Treasury, because I am aware this project exists on a guarantee from government and that it should be prioritised in terms of liquidation of its indebtedness so that they continue to support the development of the operation, the placement of jobs to our local people and also the confidence in an international market where they need to get resource to start and finish the second project,” Musukwa said

Resolute trims 2020 gold production forecast after avoiding strike at Mali mine, Syama

RESOLUTE Mining trimmed production guidance for 2020 to between 400,000 and 430,000 ounces after the company avoided a proposed 10-day strike at its flagship Syama mine in Mali. Syama accounts for about two-thirds of Resolute’s annual production with the balance mined at the Mako gold mine in Senegal. The Sydney- and London-listed gold producer said in an announcement today that a proposed strike had been cancelled, but some 15,000 oz in gold production had been lost in the third quarter as a result of stoppages. All-in sustaining cost (AISC) of between $980/oz and $1,080/oz was forecast for the year which compares to second quarter AISC of $1,033/oz (March: $1,107/oz). A “conciliation agreement”, signed between Resolute’s local subsidiary, Société des Mines de Syama S.A. (SOMISY), and the mine’s union, Union Nationale des Travailleurs du Mali (UNTM), would evaluate and support measures “… that SOMISY believes are required in response to COVID-

19 and current economic conditions”, said Resolute. Shares in the company recovered by nearly 5% in Australia today after receiving a knock last week. The market values Resolute Mining at just over A$1bn. The UNTM has agreed to be “… involved in identifying solutions and has cancelled proposed strike action at Syama,” said Resolute but the company warned there could be no guarantees. The lower guidance, which compares to the firm’s July forecast of 430,000 oz, was also influenced by potential impact of sanctions imposed by the Economic Community of West African States (ECOWAS). The sanctions related to political developments in the country that resulted in the resignation in August of Mali president, Ibrahim Boubacar Keita, following a period of civil disruption and violence.

Unique Sizer Design Proves To Be Ideal Solution For Coral Limestone

In 1989 MMD were invited to Sac-Tun mine in Mexico to investigate how a Sizer could assist with the processing of coral limestone for use in the cement industry. The mine’s existing primary jaw crusher was failing to break the limestone with the material either stalling or being ejected from the machine. MMD believed the Sizer could meet the customer’s requirements, and what followed was a partnership which has continued for over 30 years, where together MMD and the mine operators discovered that when it comes to crushing, the hardness of a material isn’t necessarily its most important attribute. All the limestone at Sac-Tun passes through one primary crushing station, so everything downstream relies on this one machine. In replacing the jaw crusher, the requirements of the Sizer were to reduce the limestone down from 1200mm lumps to 300mm, achieve a throughput average of 2,000 TPH, and remain reliable whilst being efficient to run.

Coral limestone features a honeycomb-like structure, which compresses under pressure. This elasticity means the limestone resists breaking in compression and absorbs power, making it a particularly difficult material for a traditional crusher to handle. However, because the Sizer breaks rock under tension and sheer rather than just compression, it is able to effectively cut through the limestone and avoid its natural resistance to compression. The Sizer is unique in this regard and may be the only machine capable of effectively crushing this kind of material. Once installed the Sizer was successful in breaking the limestone, however in the early days the material’s ability to absorb power meant the machine would occasionally stall. Working with the

www.subsaharamining.com | October-December 2020

customer and following some initial variations and experiments, MMD designed a bespoke drive train and spur gearbox arrangement which timed the Sizer shafts together. This resulted in double the torque now being delivered to the shafts, whilst drawing even less power from smaller motors. This proved to be an ideal solution, simultaneously being more energy efficient and eliminating any stalls. Consequently, the mine’s production rate has increased significantly and annual targets are consistently met and surpassed. Carlos Lesser, the mine’s Operations Manager of 32 years said “we’ve worked with MMD from the very beginning with a targeted production of 2,000 TPH. Today we’re producing 3,000 TPH with an even smaller Sizer than what we started with. [MMD] made an important effort to modify their technology to our specific needs and thanks to the Sizer we’ve enjoyed huge company success.”

Green Recovery in the Mining Industry Through Energy Efficient Drives Technology The mining industry must forgo its traditional energy consumption patterns, in a bid to ensure that the sector decarbonize towards a greener and sustainable method of exploration. Given the need to increase energy supply in a globally carbon constrained environment, the mining trade needs to improve its energy efficient technologies, such as electrical variable speed drives, which could reduce energy consumption drastically. The fundamentals of AC Variable Frequency Speed drive technology persist, but many elements are rapidly changing in aid to move towards a more sustainable and environmentally friendly mining future. Increasingly,

26

software is embedded in today’s mine processing components, offering new functionalities and enabling the AC drive to play a larger role in the processing plant. “Conventionally, motors run at a fixed speed, regardless of actual output requirement, wasting a tremendous amount of energy. Energy output use can be reduced by 60%, by controlling motors with electrical Variable Speed Drives.” says Stephen Brown, Danfoss Drives – Mining Accounts and Business Development Manager, Turkey Middle East & Africa. (Image: Stephen Brown, Danfoss Drives – Mining Accounts and Business

Development Manager, Turkey Middle East & Africa) New motor types are appearing, placing additional demands on motor-drive control. This in turn means that the AC drive needs to be able to control an expanding variety of motor types, without burdening the end user with more complexity. In addition, new energy efficiency requirements lead to more variable speed applications. Certain AC Drives are designed for exactly the needs of mining and mineral processing plants, coping with extreme conditions, heavy loading and controlling equipment installed a long distance away.

Mining

No matter how well the plant design has been optimised, there is always a way to drive down costs even further. AC Drives are used extensively for this purpose, extending equipment lifetime, optimizing processes, reducing maintenance and saving energy costs. The mining and minerals industry present some of the most challenging environments for production. Mine sites, mineral processing facilities, associated stockyards and ports facilities, are large scale and often in remote locations. All Danfoss Drives ≥90kW, incorporate a back-channel cooling design, with separate cooling paths for the power components, control electronics and an IP54 seal, between these two paths. This back-channel cooling removes approximately 85%90% of the power loss directly through the heatsink, leaving only 10%-15% of the total loss dissipated in the switch room. Consideration has to be given to the outside air quality, but if it is suitable, using the heatsink cooling fans and appropriate mounting and ducting, filtered external air at temperatures of up to 50 degrees Celsius, can be used to exhaust approximately 85%-90% of the heat loss from these VSDs directly outside the switch room, without affecting the switch room pressurisation.

The switch room air conditioning system only needs to be sized for the remaining 10%-15% losses. Utilising this feature can dramatically reduce the air conditioning requirements of the switch rooms and provide significant project cost savings, along with operational ongoing cost savings, compared to VSDs without such a design feature. “The mining industry is a major consumer of energy and is responsible for more than 40% of the total industrial energy use. In Sub-Saharan Africa, the energy intensive users group alone consumes over 40% of electricity produced in South Africa. Just less than 50% of the

www.subsaharamining.com | October-December 2020

energy intensive users in South Africa, are the mines”, according to Energy Minister – Jeff Radebe. It is with this need for energy efficient technology, that Danfoss South Africa is embarking on a series of informative webinars, geared towards mining engineers, specifiers, buyers, mining houses and investors alike. These interactive webinars will enable mining experts & learners alike, to think differently about their current energy usage and how the right drives are enabling energy costs savings.

Atlas Copco dealer of the year, Zenith Mining and Industrial Supplies, recently secured an order from one of their longstanding key mining customers in the Northern Cape for the supply of five Atlas Copco Hilight LED H5+ light towers mounted on double axles. “We sold our first Atlas Copco units, the older generation QAX20 generators with lighting stands, to the mine almost 20 years ago when the plant was still busy with ground clearance work,” says Zenith Founder and Director, John O`Connell. “Ensuring that we keep up to date with the latest technology from Atlas Copco, we now supply the mine with the cutting-edge compact and efficient HiLight LED units.” Currently boasting the largest installed base of 30 Atlas Copco light towers out of all the mines in the area, the mine continues to grow its light tower fleet in line with plant expansion. John first started dealing with Atlas Copco in 1995 while working at a previous company. “Soon after establishing Zenith in 2001 to service customers across the Northern Cape region, I approached Atlas Copco for

a dealership and some twelve months later Zenith joined the Atlas Copco dealer network.” “Doing business with the mines in our area since day one has put us in tune with our customers’ ever-changing and diverse needs,” says John. Initially supplying Atlas Copco pneumatic hand-held tools during the early dealership years, Zenith soon expanded its portfolio to include Atlas Copco compressors. John confirms that they currently look after more than 100 Atlas Copco compressors ranging from small Automan compressors right up to the big 250kw machines. The company’s extensive diesel portfolio includes Atlas Copco HiLight light towers and large stationary 1000kva generator plants. Atlas Copco has engineered cutting-edge design and technology into its compact and highly cost-effective HiLight LED light tower range bringing a perfect combination of high performance, optimum efficiency and low operational and maintenance costs for lowest total costs of ownership. The heavy duty IP67 rated LED lamps have an unrivalled life expectancy or lamp durability

of 50 000 hours. The flagship H5+ unit features an impressive 20 lux average and up to 5 000 m2 effective lighting coverage. The recently ordered five H5+units were available ex-stock and just had to be fitted on to the locally built double axel trailers. Trailer fabrication, which takes roughly two to three weeks, is outsourced by Atlas Copco to Anglo Welding. Moving on to his generator offering, John says that with power supply becoming increasingly erratic of late, they identified the need for more compact, mobile and efficient generator plants rather than the stationary machines. Featuring a small footprint, high efficiency and rugged reliability, Atlas Copco’s QES generators fit the bill perfectly, delivering fast, reliable predictable power at the touch of a button. Zenith has supplied the mine with trailer-mounted Atlas Copco 30, 40 and 60 kVA QES generators. Atlas Copco’s QES generator range offers a textbook balance between performance and affordability to seamlessly meet standby power requirements on mines and plants. With a 100% load

step capability, these rugged and dependable machines have the ability to work in temperature extremes from over 40°C to -25°C. With a market-leading 500-hour service interval and a short sub-two hour service routine, these generators will contribute to increased uptime and high levels of production and productivity on the job site. “We have partnered with one of the leading trailer manufacturers in Johannesburg, Anglo Welding, to fabricate tough, light-weight purpose-built trailers for the QES units that meet the exacting standards of the respective mines.” “Looking after so many machines for all our customers might seem a daunting task, but given the unmatched quality and reliability of the Atlas Copco brand, our job is so much simpler,” notes John. He adds that product flexibility is also part of the success in dealing with Atlas Copco. “We can literally help a customer irrespective of his needs whether big or small, entry level or highly sophisticated. This, coupled with the service support received from Atlas Copco’s spares and aftermarket divisions, contribute to minimised downtime and ultimate customer peace of mind.” John also applauds Atlas Copco on being in the forefront when it comes to sales and technical training offered to distributor staff on a regular basis adding that Atlas Copco understands that it is not always easy to find the right people for training on Atlas Copco equipment and machines. “We are also constantly striving to find ways of combining our products with the end users’ operators so that we end up with the perfect synergy between man and machine.” In 2017 Zenith secured the prestigious Atlas Copco dealer of the year title. “Being awarded the title for the 3rd consecutive year in 2020 was really a big surprise,” comments John. “However it was really a huge team effort and everybody at Zenith and Atlas Copco played a role in our success. In today’s tight and competitive economy, you absolutely have to have a

fluid, tight bond between your customers and suppliers as well as your own staff. This we have managed to achieve and it has paid off in spades.” Product Manager: Power and Lights, Portable Energy at Atlas Copco Power Technique, Zandra van der Westhuizen, points out that being awarded the Atlas Copco dealer of the year title means successfully ticking quite a few crucial boxes and keeping these boxes ticked for three years in a row illustrates consistency and true commitment. “In addition to achieving target and making use of our various online tools such as shop- and warrantee-on-line and toolbox, conducting customer visits with sales people and submission of monthly reports are also prerequisites.” “We look for dealers who also sell a variety of our portable product ranges including lighting plants, generators, compressors and pumps.” Zandra adds that the dealer’s marketing of Atlas Copco products which includes Atlas Copco branding on buildings, company vehicles, safety gear, etc. also come into play. “John and his team are great to work with. Working hand-inhand with Atlas Copco staff, they go out of their way to assist and support customers and are always willing to help; nothing is ever too much for them!” Wrapping up, John discusses the advantages of being a dealer for both Atlas Copco’s Power Technique and Compressors Technique business areas. “When partnering with a company like Atlas Copco there are challenges; balancing the corporate world with what we are trying to achieve at ground level is not always easy. However the positives of being associated with a renowned company like Atlas Copco most certainly adds value. We are assured of top quality, reliable products backed by a global market leader for years to come. Subsequently we have satisfied customers and I can say with confidence that on most of the mines Atlas Copco products remain first-in-mind first-in-choice.”

Energy Efficient Mining for a better tomorrow. Never has there been more of a need from the mining industry to opt for energy efficient measures on the journey to sustainability as part of a successful energy transition towards a lowcarbon future. The mining sector needs to rethink its traditional energy consumption patterns to ensure that the sector decarbonise. The decreasing costs of renewables and the proven reliability of hybrid power technologies is finally driving the interest of mining companies towards energy efficient mining practices. Decarbonisation involves the shifting of generation, transmission, distribution and usage towards a lower carbon future. This is dominated by renewable energy, e-Mobility (electric vehicles), energy efficiency, new and future fuels, such as biofuels, and demand side management.

“The mining industry is a major consumer of energy and is responsible for more than 40% of the total industrial energy use. In Sub-Saharan Africa, the energy intensive users group alone consumes over 40% of electricity produced in South Africa. Just less than 50% of the energy intensive users in South Africa, are the mines”, according to Energy Minister – Jeff Radebe. Given the need to increase energy supply in a globally carbon constrained environment, the mining trade needs to improve its energy efficient technologies, such as electrical variable speed drives, which could reduce energy consumption drastically.

Energy output use can be reduced by 60%, by controlling motors with electrical Variable Speed Drives.” says Stephen Brown, Danfoss Drives – Mining Accounts and Business Development Manager, Turkey Middle East & Africa. Therefore, Danfoss is embarking on a series of informative webinars, to address the topic of energy efficient mining, geared towards mining engineers, specifiers, buyers, mining houses and investors alike. These interactive webinars will enable mining experts & learners alike, to think differently about their current energy usage and how the right drives are enabling energy costs savings.

“Conventionally, motors run at a fixed speed, regardless of actual output requirement, wasting a tremendous amount of energy.

Ensure reliability of renewable South African energy Thyssenkrupp Industrial Solutions (tkIS) signs MoU with Wismut to deliver Renewable Underground Pumped Hydroelectric Energy Storage (RUPHES) projects in depleted gold mines Thyssenkrupp Industrial Solutions (tkIS) South Africa combines global expertise and expertise from Wismut, with local project execution know-how for efficient, reliable, flexible and cost-effective delivery of Renewable Underground Pumped Hydroelectric Energy Storage (RUPHES) projects. Following the successful court judgement against NERSA, industrial consumers will be paying R 1.28/kWh for electricity by April 2021. Consumers may be wondering why they should pay this in South Africa, a country that has abundant, world-class renewable resources. These abundant renewable resources translate into cheap renewable power. The actual agreed energy tariff with IPP’s in 2016 was R0.62/kWh for new solar and wind. There are current reports that renewables could drop further to R0.40/ kWh. The challenge with renewables is ensuring reliability. For this customers need energy storage. Converting renewables to synthetic fuels provides a level of back-up and is likely to be part of the energy mix, specifically for green synthetic aviation fuel or heavy haulage trucks. The round-trip efficiency for conversion of electricity to hydrogen and then to back electricity, is around 30%. With battery and pump storage the round-trip efficiency is 80%. The primary difference between batteries and pumped storage is that pumped storage plants last for 50 years plus using a tried and tested technology while equivalently priced

batteries of lower maximum capacity last for less than 10 years. Not only is South Africa endowed with cheap and abundant resources, the country also has the capacity for extensive underground pumped energy storage in its gold mines. Many of the gold mines are either depleted or are approaching end-of-life. Gold mines are perfect for a number of reasons. Firstly, the hard rock provides a stable geology and keeps stored water clean. Secondly, many gold mines are below waterrich karst aquifers that supply clean water to the mine below. Thirdly, South African gold mines are some of the deepest mines in the world up to four kilometres deep, which allows more energy storage per unit of water. Lastly, the gold mined in the past has already fully paid for the excavation of large underground void space needed to store water, significantly reducing construction costs.

generate. tkIS with Wismut are now in the position to offer feasibility studies leading to full project execution for cheap reliable renewable energy. As an added benefit the revitalised mine with a RUPHES provides clean water indefinitely in water scarce regions. With power increasing to R1.28/kWh these projects have an attractive business case. tkIS has engaged with IPP’s and are looking to participate in the fifth independent power procurement program. Corporate customers have the option to focus on their core business and allow the IPP to invest in the RUPHES selfgeneration and thereby use this image-enhancing environmentally friendly and sustainable technology.

thyssenkrupp Industrial Solutions (tkIS) has signed a Memorandum of Understanding (MoU) with Wismut. This builds on extensive work that Professor Frank Winde undertook with a consortium including South African and other German research organisations in 2017. Prof. Winde was then with the Mine Water Research Group, and now with Wismut in Germany. Current financial constraints in the power sector and decision to suspend these projects provides an opportunity for customers who wish to selfgenerate, or utilise an IPP to

The WEDA series boast flow rates of up to 16,500l/min with power ratings up to 54kW and can manage water with specific gravity up to 1700kg/m3.” WEDA D drainage pumps are designed to pump water containing abrasive solids of 4 to 12mm dia. Featuring a topdischarge function, these drainage pumps are capable of handling water with specific gravity to 1100kg/m3. For optimum flexibility, discharges can be mounted vertically or sideways as required. WEDA D pumps are ideal for an extensive range of applications such as ground and raw water removal, excavation and open pit dewatering as well as storm water and flood control. Highly suited to tough conditions, the WEDA S range is capable of pumping sludge, light slurry and muddy water containing abrasive and larger solids of 25 to 50mm dia. These pumps can handle the dewatering of liquid sludge, thick, soft, wet mud or other similar viscous mixtures of liquids and solids typically resulting from an industrial or refining process. With a bottom side discharging capability for the handling of water with specific gravity to 1400kg/m3 , WEDA S pumps are ideal for tank clean-out, agricultural product

38

wash-down pits and trench and pond cleaning. The WEDA L slurry pumps are designed for the dewatering of abrasive media with a high solid content typically found in quarrying, mining or dredging applications. These pumps efficiently manage semi-liquid slurry mixtures usually made of fine particles of manure, cement or coal, and water. The large apertures of the rugged WEDA L series facilitate the handling of slurry containing solids of 20 to 60mm dia. while the highefficiency high-chrome agitator facilitates the lifting of settled solids. Also using a bottom side discharge, WEDA L pumps manage water of specific gravity up to 1700kg/m3. All pumps in the drainage (WEDA D) and slurry (WEDA S) ranges are available with WEDA+ features which include phase failure protection, rotation control, thermal switches and a 20m cable with phase shifter plug for all 3 phase pumps. The WEDA+ features are also available as an option on the L range “Atlas Copco has focused on not only optimising the performance of the WEDA series but also on making the pumps lighter, increasing their electrical safety, improving the seal design and simplifying installation and maintenance,” notes Stanford. The more compact design, coupled with a 20% lower weight compared to similar products,

simplify handling and transportation, making these pumps particularly suited for the rental market. The pumps’ light weight is due to the use of unique aluminium alloy which also offers strength and corrosion resistance for seamless and reliable operation in harsh environments across all applications. These robust pumps feature rugged components, class F motors and class H electric motor insulation. The starter and motor protection system are built in, and a double silicon carbide mechanical seal prevents the ingress of contaminants. The pumps include adjustable wear-resistant rubber diffusors, hardened highchrome (55HRC) impellers and heavy-duty bearings (that can withstand shocks and overloads) which further enhance pump durability. Maintenance on these pumps is quick and hassle-free, keeping uptime to the max. External oil inspection and grease- filling plugs are easy to access, and all pumps conveniently contain seal types appropriate to their size. Atlas Copco supports WEDA pump customers across the southern African region through readily available products, parts and spares backed by exceptional service delivery from its team of skilled service technicians and strategic dealer network.

TOMRA’s promise to diamond mining operations: 98% diamond recovery guaranteed Maximizing diamond recovery while optimizing costs: this is the priority at the top of the list of every diamond producer. With TOMRA’s holistic approach and cuttingedge technologies, both can be achieved to deliver outstanding results. TOMRA is today the world’s leading supplier of X-Ray Transmission (XRT) diamond recovery technology, having recovered some of the largest and rarest gemstones in history. A complete solution and holistic approach to deliver TOMRA’s customer promise TOMRA approaches every project as a partnership with the customer to deliver a complete solution that meets their operational and business requirements. It begins with a detailed analysis of the customer’s requirements and operational needs. Working collaboratively, it assists in developing a tailor-made flow sheet redesign that combines its ground-breaking XRT technology with its Near Infrared (NIR) and Laser solutions as needed. This collaborative approach continues throughout the project, with testing at its Test Center in Germany

and on-site as required, through to installation and beyond. The complete solution can also include the webbased TOMRA Insight platform that turns all the sorters into connected devices for monitoring and tracking the system’s performance. Once the system is fully operational, TOMRA remains at the customer’s side through its Service Level Agreement, unique on the market, to ensure the solution continues to deliver the desired results. The tailored agreement can include on-site presence as required, 7 days/week product support, application engineer visits, tiered urgency support, targeted site response, training, as well as spare and wear parts coverage to ensure maximum uptime and protect the customer’s investment. Advanced technologies add value at various stages of the process TOMRA’s XRT technology recognizes and separates material based on its specific atomic density. It uses a cuttingedge X-Ray camera with DUOLINE® sensor technology to measure spectral absorption

information. TOMRA’s proprietary high-speed XRay processing unit uses the data to produce a detailed “density image” of the material. The result is a high level of purity in sorting materials, irrespective of size, the degree of moisture or surface pollution present. TOMRA’s XRT highcapacity sorters are incredibly effective in the recovery of free, liberated diamonds at high feed rates up to 300 tph. TOMRA’s NIR sorters recognize and separate Kimberlite and waste rock based on their chemical composition. This technology is useful in upgrading lower grade ROM and stockpiles, producing a Kimberlite concentrate for further processing. Marie-Claude Hallé had first-hand experience of how TOMRA’s solutions can add value to diamond mining operations when she held the role as Marketing Operations Manager for leading Canadian diamond exploration and producing company Stornoway Diamonds: “You have to really envision that TOMRA has actually changed the game in terms rough

diamond recovered around the world and allowed producers to access large exceptional quality goods that perhaps in the past would be crushed to pieces.” Customized solutions for Kimberlite, Lamproite and Alluvial applications With its customized approach, TOMRA can deliver on its promise of guaranteed results both in hard rock Kimberlite/Lamproite, and Alluvial deposits – each of which presents their specific challenges. In Kimberlite, the challenge is to recover ‘needle in a haystack’ diamonds, which requires controlled crushing of kimberlite ore to avoid damaging or breaking the diamonds. High waste dilution impacts the crushing energy needed and further increases diamond breakage risk. Utilizing TOMRA NIR technologies we can remove non-diamond bearing material, not only improving the crushing profile of the ore, but also increasing the value of each ton of ore processed. TOMRA NIR waste sorting technology can make diluted marginal kimberlite deposits economic. Additionally, complex, energy- and water-intensive Kimberlite liberation processes, and the cost of transportation for crushing and processing are challenges facing modern diamond miners today. TOMRA’s XRT and NIR technologies, which offer extremely high concentration factors, allow the production of hand sortable, ultrahigh grade concentrates in as little as two stages compared to up to seven in traditional methods. The challenge of economically mining low-grade alluvial deposits is due to their typically lower grade and the sporadic nature of the deposits. The high recovery performance of TOMRA’s XRT technology enables single-stage or double-stage diamond recovery, offering a drastically lower Operating Cost and Capital Investment so that mining marginal deposits becomes economically viable. Another advantage of TOMRA’s XRT solution is that it can operate as a dry process, which dramatically reduces its environmental impact and operational complexity. Besides, it opens the door to new opportunities, making it possible to mine deposits in arid areas where water access is minimal. TOMRA XRT machines have proved effective in alluvial operations. One such case is that of the Lulo mine in Angola operated by Lucapa Diamonds, where TOMRA XRT

technology is used to process material between 18 and 55 mm in size and allows the recovery of diamonds up to 1 100 carats – and where it has recovered Angola’s second-biggest diamond on record in 2017, a 227-carat stone. “The recovery of the 227-carat diamond using the new XRT circuit justifies our investment in TOMRA’s large diamond recovery technology, which has more than paid for itself with the recovery of this one stone alone,” commented Stephen Wetherall, Lucapa Diamonds Managing Director at the time of the recovery.

environmental impact of the recovery process. An additional benefit of TOMRA’s solution is that it is a fully automated process, so that there is no manual handling during preconcentration and recovery, which has positive implications on security and eliminates human error resulting in greater accuracy. High recovery rate TOMRA’s sorters not only stand out for their high capacity, they process these large volumes with great efficiency, finding more diamonds than other, traditional separation methods – including coated and low- or nonluminescent diamonds. The performance of its XRT sorters is independent of the heavies content in the feed, and is ideal for processing high-yielding ores unsuitable for Dense Media Separation.

Optimized flow sheet redefined: cuts down on complexity and costs, maximizes efficiency and recovery TOMRA is in the unique position of being able to offer diamond operations a full XRT recovery flow sheet to 2mm that delivers concentration factors up to 1 Million with a much-reduced number of concentration stages. “TOMRA XRT technology replaces multiple stages of diamond concentration by virtue of its ability to concentrate diamonds to a hand sortable product after only a single step,” explains Geoffrey Madderson, Diamond Segment Manager for TOMRA Sorting Mining. “This concentration factor allows for the removal of multiple recovery steps, drastically reducing both the capital investment and operational costs to recover Diamonds.” TOMRA’s XRT technology can replace traditional methods such as Dense Media Separation (DMS), wet magnetic separation and XRL final recovery with single-stage solutions for +8mm and doublepass for -8mm +4mm particles. TOMRA’s solution eliminates up to seven concentration stages, dramatically reducing the complexity of the supporting plant and infrastructure. This results in significantly lower power and water consumption, which not only reduces costs, but also the

Large diamond recovery With TOMRA’s sorting solutions, diamond producers can install Large Diamond Recovery systems with a small capital investment and operate with a fraction of operating expenditures per tonne compared to traditional recovery methods such as DMS and XRL. In addition, the economic recovery of Ultra Low-Frequency Exceptional Diamonds of +32mm is now possible. TOMRA’s XRT technology has exceeded all expectations at Lucara Diamond Corporation’s Karowe mine in Botswana with a string of record-breaking diamond recoveries. TOMRA’s Large Diamond Recovery circuit was installed in 2015 and Eira Thomas, Lucara Diamond CEO is fully satisfied: “We felt, certainly, that the technology that TOMRA offered was the best. But, more importantly, I think it was really around the approach, the attitude of collaboration and willingness to actually work with Lucara as we undertook to solve this problem.” “TOMRA’s ability to deliver not only a technology that can detect such large diamonds but also an economical process solution for the recovery of ultra-rare, exceptional diamonds, is what sets it apart from its competitors. This is the reason that to date, TOMRA XRT has become synonymous with the recovery of extraordinary diamonds from all around the world,” concludes Geoffrey Madderson.

emission series. “In 2015, we put the first battery-powered rammer on the market and from the start, designed a sustainable system for our customers’ purposes. Today, the modular battery can be used in seven units,” says Alexander Greschner, Sales Director of the Wacker Neuson Group. “With the miniexcavator EZ17e, we have expanded our zero emission series. With more than twelve machines, an entire inner-city construction site can be operated completely free of exhaust emissions – without limitations in the sequence of operations or in performance, not least because of the consistently retained zero-tail design.” That the trend is heading in this direction is also shown in the increasingly stricter specifications for environment and user protection on the national and

international levels. Further, various cities are thinking about requirements for pollutant reduction, particularly in the area of the inner cities, and are beginning to support the application of low-emission machines. Intelligent battery management The first question when it comes to battery-powered equipment: How long can I work with the battery? Wacker Neuson’s answer: a whole workday, even without intermittent charging! The mini-excavator EZ17e, with its integrated lithium-ion battery, can be used either without a power cable or also, during stationary activities, charged at power sources from 100 to 415 volts in ongoing operation. At all times, the operator can see

the current charge level of the battery but also, for example, track whether the power supply network on the construction site is overloaded and take the excavator off the network if necessary. A full charge can be achieved at a household outlet (110-230 volts) or by quick charging with high-voltage current (415 volts) in only four hours. Highquality lithium ion battery technology has been in use by Wacker Neuson for several years already and is especially durable. It ensures that all hydraulic functions have the performance of a conventional model of the same class. This way, customers can be sure of working just as flexibly and efficiently with the electric excavator as with a dieselpowered machine – in short: no exhaust emissions, no compromises. “With the EZ17e, we have implemented a zero-tail concept with generous performance dimensions. With the efficient, intuitive and emission-free excavator, we satisfy the high standards of professionals who work in particularly confined space conditions, as is usual in interior demolition, for example,” says Stefan Bogner, managing director of Wacker Neuson Linz GmbH, the research and development center of expertise in excavators within the Wacker Neuson Group. Due to the battery system with integrated battery heating, the excavator can be operated even at low outside temperatures. It just has to be connected – the integrated battery management system does the rest. Besides the easy handling, customers benefit from minimized maintenance and service costs as well as

lower energy costs in operation. At the beginning of 2020, the excavator was given the SaMoTer Innovation Award for its efficiency, an optimum integration of the electric drive in the zero-tail concept, and its performance.

The zero emission solutions are usually applied in environments in which exhaust fumes and noise should be avoided, for example for demolition and reconstruction work indoors or on night job sites in the inner city.

Flexible in application – easy to operate The mini-excavator is a zerotail model, i.e. without rear overhang. This makes it particularly maneuverable and compact, and thus ideal for application on cramped construction sites or indoors.

About the Wacker Neuson Group The Wacker Neuson Group is an international family of companies and a leading manufacturer of light and compact equipment with over 50 affiliates and 150 sales and service stations.

An intuitive operating concept makes it easy for the operator to keep all functions within view. The excavator can be easily steered using a Jog Dial system. All important information, for example the charge level of the battery, is clearly shown on the 7-inch full color display. There is also the new option of operating the quick hitch system via the display, no longer via the dozer blade lever. Completely emission-free construction sites are becoming a reality The zero-emission series by Wacker Neuson currently includes three batterypowered rammers and three battery-powered vibratory plates, a dual power miniexcavator that can be operated with an electrohydraulic drive unit in addition to the diesel engine, an electric mini-excavator, an electric wheel loader, electric track and wheel dumpers and an internal vibrator system for concrete consolidation. With this wide-ranging portfolio, a typical inner-city construction site can be operated emissionfree and at low noise levels.

Thyssenkrupp locally engineers and manufactures mobile disinfectant trailer to fight COVID-19

In a bid to fight the COVID-19 pandemic, thyssenkrupp Industrial Solutions South Africa (tkISSA) has locally engineered, designed and manufactured a customdesigned, portable Sodium Hypochlorite disinfection trailer unit for spraying disinfectant in COVID-19 hotspot areas to help curb the spread of the virus. The primary way that the extremely contagious virus spreads is from person to person but as the virus attaches to surfaces, infection can also occur by people touching their face after touching an infected area. The World Health Organisation (WHO) suggests Sodium Hypochlorite, commonly known as bleach, for effectively disinfecting surfaces potentially infected with COVID-19. As chemicals should be used at the lowest possible effective concentration for safety reasons, the WHO recommends a 0.5% Hypochlorite solution which is achieved through one part bleach (household bleach is commonly available as a 3.5% concentration) to seven parts water to kill the virus. This dilution is as good as the alcohols used in hand sanitisers. thyssenkrupp has designed the trailer unit for effectively

spraying the recommended 0.5% Hypochlorite concentration over large street, pavement and vertical surfaces. thyssenkrupp is globally renowned for its engineering capabilities when it comes to machines and equipment for the mining, minerals processing and cement sectors as well as for its cutting-edge technologies such as solar and biomass. “By combining these proficiencies together with our local fabrication expertise, we have produced this robust and costeffective trailer,” says Neville Eve, GM Chemical Process Technology. Equipped with a 500 litre easyto-refill concentrate tank, the Hypochlorite trailer can spray a 50 000 sqm surface area per day with the replenishment of water only into the diluted liquid tank. The unit is fitted with four spay nozzles allowing four operators to efficiently spray both sides of the street simultaneously. Weighing 1 600 Kg (gross), the trailer is easily towed by a bakkie or light utility vehicle and is ideal for use by local municipalities, health departments, industrial cleaning companies, etc. Thanks to the smart modular design, multiple units can be manufactured with very short lead times. Although the trailer is extremely easy to operate,

Thyssenkrupp Industrial Solutions’ multi-disciplined approach in the stand against COVID-19 As the COVID-19 pandemic tightens its grip, thyssenkrupp Industrial Solutions is assisting customers to maintain operational efficiencies through sustainable service delivery and innovative technologies. “The global economic crisis, as a consequence of the COVID-19 pandemic, has put the drive for efficiency into top gear,” states Philipp Nellessen, CEO of thyssenkrupp Industrial Solutions Sub Sahara Africa. “Fundamental to this drive is cutting-edge technology. Through our ongoing investment in people and R&D and our over 200 years of expertise, we are able to develop advanced technologies to assist mining and other industries in achieving maximum operational efficiencies.”

The engineering powerhouse has also applied its technology prowess to assist the general public in the fight against the spread of the virus with the development of a Sodium Hypochlorite mobile trailer for spraying disinfectant on the streets in COVID-19 hotspot areas. “Our easily portable Sodium Hypochlorite disinfection trailer unit is designed to efficiently spray a diluted (0.5%) Hypochlorite concentration over large street, pavement and vertical surfaces to limit the spread of the virus,” says Neville Eve, GM Chemical Process Technology. He adds that the prototype of this robust, modular and costeffective unit is already available and multiple units can be manufactured with very short lead times.

Thyssenkrupp has a large portfolio of technologies Two of the company’s leading technologies are solar thermal heat coupled with biomass fired plant solutions for sugar plants (from the boiler to the integrated sugar plant). This technology is new and significant in the market since operating costs are optimised with low capital investment. Wilfred Barkhuizen, thyssenkrupp Industrial Solutions Sub Sahara Africa GM Mining, explains that sugar plants use biomass residue from sugar cane (Bagasse) to produce process steam and electrical power which is primarily used to drive sugar plant machinery with surplus power fed to the power grid. Sugar plants are typically operational for only a portion of the year and the amount of raw material is only sufficient to produce power for roughly six months.

Industrial

Subsequently, high CAPEX equipment (boiler, turbine, generator, etc.) stand idle for the remainder of the year. “Taking our innovation capabilities a step further, we can combine our technologies to offer customers unsurpassed and highly cost-effective solutions. By integrating, for example, solar thermal heat technology systems with the biomass power plant, customers can extend their power production by a few months as well as their use of limited resources, thereby reducing their O&M and monthly expenditure,” says Barkhuizen. Although the South African mining industry was not operational during national lockdown Level 5, critical repairs were still permitted. As an essential service provider, thyssenkrupp has been delivering maintenance and repair as well as rebuild work to local mines. The company assisted a platinum mine in Limpopo Province with a roll change on one of their flagship products, a High Pressure Grinding Roll (HPGR). “The scope of work required a rebuild on the HPGR set as well as the installation of the hardware on the mine site, making this our largest project in the national lockdown period,” says Nico Erasmus, thyssenkrupp Industrial Solutions Sub Sahara Africa Head of Service Operations. “We are very pleased that even in a complete lock-down situation, we were able to complete the project in a healthy and safe manner, in excellent cooperation with our customer,” says Erasmus.

measures. According to Erasmus, despite several challenges, the team adapted quickly to all the controls while still being responsive enough to get the work done safely and within the scheduled timelines. “The transport of super loads (two trucks with 120t loads each) was a real challenge but our logistics team rose to the occasion and got the loads on site in no time and ready for installation,” says Erasmus. In order to remain operational and continue seamless service delivery to customers, thyssenkrupp has implemented all necessary policies in line with Government COVID-19 regulations. These include possession of all essential services permits and strict entry control protocols for employees, visitors and suppliers at all premises. Employees are required to attend mandatory training sessions conducted by the OSH department, wear all necessary Personal Protective Equipment (PPE), sanitise regularly and maintain social distancing. A dedicated COVID-19 committee has been set up to assess changing regulations and risks associated with office and site working environments. “With the majority of employees working from home, we have faced our fair share of challenges but the process was very well organised with IT managing it all incredibly well ensuring that everybody was equipped in time,” notes Erasmus. “We only had one day of downtime at our essential service workshop site. The pandemic has

significantly changed the working landscape but thanks to our flexibility, employees will be able to carry on doing the majority of their work from home as we continue to offer the same high levels of service our customers have come to expect,” adds Erasmus. Wrapping up, an optimistic Nellessen says that he is in no doubt that South Africa/SubSahara Africa will recover. “The people here are incredibly brave and innovative and companies will find their way out of the crisis. We have seen a significant decline in order intake in the last few months, especially in our chemical business with some of our customers having been dealt a double blow – COVID-19 and an unpreceded decline in commodity prices in the oil & gas sector of the global economy. As industry partners, we are here to offer our support. Despite tough times ahead for some industries, the mining sector continues to show growth and here I foresee a restart and a good recovery, depending on mining commodities probably taking anything between three to twelve months to reach previous and required pricing levels.”

“Our customer had excellent controls in place and we complemented the risk mitigation with our own additional preventative protocols,” explains Erasmus. Procedures included preselection of a team that falls inside the recommended age and health categories, prescreening at both thyssenkrupp and customer sites, limiting the amount of people on shifts and in spaces, adhering to stringent hygiene measures (hand sanitising, wearing face masks, social distancing, cleaning of surfaces, tools and equipment), and implementing special transport and accommodation

In the modern age of industrial innovation, it has become more important than ever to analyse the performance of every tool at your disposal. The margin between success and failure, profit or loss may be determined by the small differences in production times and costs we often take for granted. More often than not we do things the same way we have always done them, even though the parameters and environment we operate in have changed. Why spend four hours cutting and grinding to complete a job and get it ready for shipping when one hour will do? Why wait another day to invoice a job that could have been delivered today? Construction; In its most widely used context covers the processes involved in delivering buildings, infrastructure and industrial facilities, and associated activities through to the end of their life. Construction also covers repairs and maintenance work, any works to expand, extend and improve the asset, and its eventual demolition, dismantling or decommissioning. In general, there are three sectors of construction: buildings, infrastructure and industrial. Infrastructure, also called heavy civil or heavy engineering, includes large public works, dams, bridges, highways, railways, water or wastewater and utility distribution. Industrial construction includes offshore construction (mainly of energy installations), mining and quarrying, refineries, chemical processing, power generation, mills and manufacturing plants. Today a wider variation of construction materials is being used than ever before. Some alloys are lighter, and or harder, more abrasionand-impact resistant, while others tend to react better to sub-zero temperatures or prove more heat sensitive than ever before, the same can be said for the various concretes being used in the construction applications. These new age construction materials have been developed because the world we live in demands it. Seldom do we stop and put some thought into the machining, grinding and finishing of the said alloys until that moment of truth arrives. Luckily, our abrasive technology has developed at equally rapid rates. Manufacturing methods,

bonding systems and mineral types have been evolving to keep up with the demands created by new modern innovative alloy introductions. At Grinding Techniques â&#x20AC;&#x201C; a Tyrolit company, we are at the cutting edge of development and able to provide a solution for all your abrasive requirements. When one looks at the new age of construction materials being developed, it has become increasingly evident that cutting and grinding of these materials will be and is already a serious challenge. Grinding has proven to be one of, if not the preferred method, of shaping these alloys. Abrasive manufacturers all over the world are gearing towards the grinding, shaping and machining of these alloys with a far greater success rate over that of the machine tool bit manufacturers. New innovative products being developed have brought grinding and machining times of certain components down from 4 to 6 hours per part, to less than 24 minutes per part. The ability of cutting these new age products, on site or in a fabrication facility has become just as important. Being able to cut quickly to save time while having a better life expectancy of the abrasive product, being able to cut with minimum material losses and more importantly being able to cut these products safely is at the forefront of Grinding Techniques development plans. The SUPERFLEX Ceramic range of grinding tools are developed for rapid and accurate cool grinding on specialised alloy castings in excess of 700HBR. When comparing to conventional abrasive tools, the results are almost incomparable. Grinding times on these hard materials have been reduced by more than 66%, and as a result of the shortened grinding times, heat being generated through friction is lessened by significant proportions with noticeable cost saving as a result. Scrap rates as a direct result of heat cracks are now something of the past.

Choosing the correct tool for the job is critical, as great as the ceramicbased grinding range is, it is best used on Chrome and abrasion resistant materials and does not provide the same performance level on material such as cast iron, sg irons, manganese and steel foundries. So, which is the best product to grind with, and what about the correct cutting disc? Is the industry more in need of thin line cutting discs or more conventional cutting discs? Where does one really begin in choosing the most appropriate tool for the construction industry and all the new age materials being used in the industry? It starts by challenging yourself to achieve a more desirable result and produce a better end product at a satisfactory cost level for the specific application. Factors to consider should include answers to questions like â&#x20AC;&#x201C; Do you need faster grinding times with less of a bottleneck in your fettling bay, lower grinding costs per component, reduced machine-or-replacement costs or better aesthetic finishing. By selecting the correct abrasive type, all of them or at least a combination of them is possible. Grinding Techniques â&#x20AC;&#x201C; a Tyrolit company, offers a comprehensive range of abrasives geared towards achieving your required optimum result. With more than 100 years of manufacturing experience behind us, we are more than willing to conduct trials, assist with application optimisation, and work along-side you to tailor make a solution that attains your required result. Our comprehensive product offering uniquely qualifies us to assist in optimising your foundry requirements and making the correct tool choice.

Looking to increase locomotive availability? Focus on your most vulnerable component: batteries. Diesel engine starting systems require a quick burst of power, which is hard on a battery. A battery-only solution expected to provide in excess of 1,500 amps during start-up cranking, creates a large voltage drop that can reset electronics, causing a penalty brake application.

means less energy drain from batteries, longer battery life, less time to recharge batteries, faster cranking speed and outstanding locomotive reliability,” Nelson explains.

A large voltage drop at start-up is just one problem. Locomotive subsystems—safety, communications, PTC, health monitoring—have significantly different requirements that are a constant low-current draw on the batteries. All of these requirements can limit a battery’s useful life, weakening it, resulting in starting difficulties, the worst of which is known as a DWS, or “Dead-Won’t-Start.”

“From switchers to main line locomotives, KickStart has proven its versatility in helping virtually any locomotive type,” Nelson says. “It has improved starting reliability in the freight and passenger rail industries, modern and older fleets, and both high- and medium/lowhorsepower locomotives. In fact, many KickStarts have been applied to highhorsepower locomotives that are 25 years or younger.”

According to ZTR, the best source for the variety of power required by locomotives is a combination of lead acid batters and supercapacitors. “This combination provides the right jolt of starting power while allowing the batteries to supply the necessary power for other systems,” ZTR Railway Division Director of Sales, Brian Nelson says.

“The ZTR KickStart™ uses supercapacitor technology to bolster locomotive batteries during the engine start, reducing battery strain. That

54

locomotive requires less cranking time to start, reducing wear and tear on these systems. And for onboard systems, KickStart reduces voltage drop during the starting phase to help preserve onboard electrical power, which is critical for reliable, continuous operation of systems including PTC, communications and health monitoring.

Conventional locomotive batteries are slow to recharge and slower to deliver energy, ZTR points out. Daily recharges will affect overall longevity. Batteries require periodic maintenance, last about 1.5 to 5 years—often with a rebuild, and could exhibit reduced performance. Supercapacitors, on the other hand, deliver high power quickly, are capable of one million cycles, require zero maintenance, and offer a lifespan of 10-plus years, with strong performance in all weather conditions.

The ZTR KickStart “has revolutionized locomotive starting power with supercapacitor technology,” adds Nelson. “KickStart™ is rapidly proving its worth with our customers, for one very simple reason: It effectively addresses the DWS problem.”
