Working towards environmentally friendly lithium extraction methods

0

Lithium is a crucial component in the switch to renewable energy, but the extraction process of this critical mineral has been costly to the environment.

Lithium arguably plays the most important role in ditching fossil fuels and ensuring the world can move towards a zero-carbon future. The lightweight metal is found in rechargeable lithium-ion batteries, which are used in most personal electronics and most importantly, electric vehicles (EVs).

The demand for EVs has seen a huge increase in recent years, with companies scrambling to target multiple lithium exploration projects to ensure lithium supply can meet demand. However, in order to ensure the safety of our planet, lithium extraction methods must be done in an environmentally sensitive way that causes as little damage.

Any type of resource extraction is harmful to the planet, with removal of raw materials resulting in oil degradation, water shortages, biodiversity loss, damage to ecosystem functions, and an increase in global warming.

The Innovation Platform takes a look at why lithium extraction is bad for the environment and how companies are ensuring their extraction methods are eco-friendly so that we can meet the ever-growing demand for lithium.

The increasing demand for lithium

 Lithium demand is higher than ever, with calls for at least $42bn in lithium investment over the next six years in order to meet 2030’s goal of 2.4 million tonnes of lithium production per year.1

 The demand for lithium is so high due to its integral role in EV batteries. EVs are becoming increasingly common on our roads, with over two million vehicles sold in 2018 alone.

The growing interest in lithium has seen the world’s largest-known reserves increase significantly. According to the US Geological Survey, there are around 80 million tonnes of identified reserves globally.2

Lithium is irreplaceable for the high-energy batteries that power portable electronics and electric vehicles. It has a unique position on the periodic table, offering high voltage and high capacity that cannot be replicated by other metals. A select few battery technologies have shown potential to one day replace today’s lithium-ion batteries. These new batteries are based on lithium metal and lithium silicon anodes, which improve performance but also increase lithium usage per kilowatt-hour.

After South America – mainly Bolivia, Chile, and Argentina – the next biggest lithium-producing country is the US, followed closely by Australia and China. In 2019, lithium exports from Australia were reported to have totalled almost $1.6bn.

Lithium is mainly sourced from either spodumene or brine. Australia is home to the majority of hard rock (spodumene) mines, while brine production is concentrated in South America, mainly in Chile and Argentina.

Lithium carbonate and lithium hydroxide are the two lithium compounds employed for battery cathode production, with carbonate currently making up the bulk of usage. In brine production, lithium chloride is extracted from alkaline brine lakes before being converted to carbonate.

With this in mind, it is crucial to explore how these different extraction methods impact our planet and ecosystems.

Why is lithium extraction bad for the environment?

 Despite its potential to power a net-zero future, lithium extraction methods can cause great damage to the environment, with the metal often described as the non-renewable mineral that makes renewable energy possible. Extraction of the product causes several environmental defects, including water contamination and increasing carbon dioxide emissions.

Zambia: Climate Change Action Could Set Off a Copper Mining Boom – How Zambia Can Make the Most of It

0

At last year’s US Africa leaders summit in Washington the US signed an historic memorandum of understanding with Zambia and the Democratic Republic of Congo to develop an electric vehicle battery supply chain.

At the summit, Zambian President Hakainde Hichilema also announced that Kobold metals, an exploration firm backed by billionaires Bill Gates, Jeff Bezos and Richard Branson, will invest US$150 million to develop a new mine in Zambia.

Zambia is particularly well positioned to supply what the world needs. It has substantial reserves of copper and cobalt, critical metals for the transition from fossil fuels to renewable energy. Due to their broad uses in wind and solar powered technology and electric vehicle production, these metals will play a crucial role in a low carbon future.

Copper demand is expected to increase up to threefold by 2040 while cobalt demand is expected to rise over 20 fold.

Zambia has 6% of the world’s copper reserves, and the metal accounts for up to 80% of its export earnings.

The coming copper boom presents Zambia with an extraordinary opportunity – to enable mining profits as well as to power inclusive growth.

But, as Zambia’s history shows, this is easier said than done. Successive rises in copper prices have not translated into reducing poverty or inequality. Zambia is still the fourth most unequal country in the world.

Based on our published research and expertise – including work with the International Growth Centre in the London School of Economics and engagement with the Zambian government on a research agenda for the country’s mining sector – we argue that Zambia can benefit from the energy transition underway. But it can only do so by harnessing the non-tax benefits of mining.

Non-tax benefits are the opportunities that stem from the mining activity itself. Most mining firms spend the bulk of their revenue on operational and capital expenditures, a larger share than goes towards either profits or government tax.

Sedna, Globalstar deal keeps African miners connected

0

In a powerful move to connect and protect mining assets, improve data connectivity, and save lives, Africa-focused industrial IT solutions provider Sedna has partnered with telecom infrastructure powerhouse Globalstar.

Band 53/n53 is a mid-band licensed spectrum resource that Globalstar offers to partners and customers that otherwise would not have access. Spectrum is sorely needed for progress in Africa. In line with demand for faster and more reliable speeds, the 5G variant of Globalstar’s Band 53 is known as n53.

“Demand for wireless data solutions from heavy industrial uses in mines is on the rise, but access to reliable always-on solutions is a challenge,” says Anton Fester, Sedna managing director.

“Access to reliable data and connectivity is an imperative for miners and their managers, as reliance on Wi-Fi alone is not enough, while access to spectrum is a continuous challenge. Globalstar’s terrestrial spectrum offers an immediate solution and we are delighted to be joining forces with a renowned global innovator like Globalstar to bring secure, reliable and state of the art data connectivity solutions to mines across the continent.”

He furthermore describes the deal as “an extremely important and exciting development for Africa’s mining industry.”

“The addition of n53 and 5G status ensures we are in lock-step with the latest digital advances and the Fourth Industrial Revolution as new networks around the world will be built utilising 5G’s advanced technology. There is already a lot of demand for these solutions as spectrum is also critical to the deployment of private LTE solutions on mines, which we are already rolling out.”

Band 53 offers partners secure and reliable connectivity in any environment and utilizing the band allows customers to deploy considerably less access points than when relying on Wi-Fi, leading to superior security, performance and long-term value.

Globalstar vice president of strategy Kyle Pickens says, “We are excited to be working with Sedna to bring Band 53/n53 connectivity to their mining deployments in Africa and beyond. Mining is a critical endeavour for the global economy and ever more important in many of the countries in Africa where Sedna is focused.

“The ever changing landscape make network design difficult and the environment is dangerous adding value to automation. Private wireless networks like we can deploy with Band 53/n53 are great solutions for Sedna’s business and the mining industry.”

Founded in South Africa in 2006, Sedna has rapidly expanded its solutions and innovation to serve mines globally (it has active operations on three continents) with scoping, sourcing, installing, and supporting enabling operational technology (OT) network technologies.

Sedna installed Africa’s first licensed spectrum private LTE (pLTE) network in South Africa as well Africa’s first underground leaky feeder licensed spectrum pLTE network.

“We aim to expand our solutions broadly across the continent. This will include developing adequate use cases to address customer needs. Innovations include automotive solutions through the power of AI, mobile connectivity for sensors, and geofencing for workers’ safety, among many others. The world is truly in the network, and by harnessing these innovations Africa’s heavy industries can thrive, survive and grow,” says Fester.

Sedna continues to expand its trusted partnership eco-system. Last month it strengthened its partnership with Nokia to co-operate on the technological advancement and development of Africa’s mining sector. It is now Nokia’s main system integrator for Africa in mining and other industrial applications.

“Our aim is to be a next-generation solutions provider to mines and other heavy industries across Africa. Technology has the power to ensure Africa’s growth trajectory is accelerated and with partners like Globalstar, we will continue to drive this growth with tailored, cutting edge solutions,” concludes Fester.

Sandvik’s battery electric range paves route to mine of the future

0

Sandvik has long been a leading innovator in mining technology, and the launch of its battery electric vehicles now brings opportunities previously only dreamed about by the mining sector.

Speaking recently at the Electra Mining Africa exhibition in South Africa, Sandvik vice-president strategy and commercial Jakob Rutqvist, explained that this leap brings a full package of benefits. Not only is battery-driven equipment a practical response to health, safety and decarbonisation priorities, but it also delivers higher production rates and increased tonnages.

“Mines will find this technology exciting because it addresses such a range of imperatives facing mining today,” Rutqvist says. “The future of mining is more responsible, looking for lower carbon emissions and healthier working conditions. At the same time, mines need to produce more with less, and they therefore need to be more efficient in the use of resources and assets.”

He highlights that the future of mining is electric, automated and digital. Sandvik innovates in all three spheres, but its experience in electric vehicles dates back decades. The company has been supplying the sector with electric machines since the 1980s, he says, but this was cable technology. Its application was limited to those mines designed with the necessary infrastructure to support the power supply cables – and presented some operational limitations.

At the Sandvik exhibition stand at Electra Mining Africa 2022 was an entirely new proposition: a battery electric vehicle (BEV) designed from the ground up. With a 65-tonne payload, Sandvik’s TH665B is the world’s largest underground mining truck – powered by an 8-tonne battery built with mining in mind.

“The rapid evolution of battery technology has allowed Sandvik to accelerate its BEV developments, but our strategy has been to design for mining – not just to convert designs from other sectors,” he says. “Neither did we want to simply convert our diesel-driven machines, and just replace an engine with a battery.”

With this vision, Sandvik acquired Artisan Vehicle Systems in 2019, a US-based supplier of battery electric vehicle solutions for underground mining. This was integrated into Sandvik Mining and Rock Solutions, giving the company a head-start over its competitors.

“The Sandvik approach to the Fourth Industrial Revolution starts with our customers,” he says. “While it is easy for engineers to get carried away with today’s technology, we must find the value that we can add to customers’ operations – their safety, productivity and other opportunities.”

The kind of challenge to be solved was a deep level gold mine in Canada whose ventilation costs at depth was making their mineral deposit unviable. In this context, the BEV was a targeted solution that made mining possible and profitable.

“Over half of the global mining sector has committed to net zero emission goals in the coming decades, and are looking for practical ways to decarbonise their operations,” he continues. “In a typical underground mine, 50 to 60% of emissions come from the mobile fleet – and about half of this will be from the primary haulage equipment.”

Trucks and loaders are therefore a good place to start looking for solutions, and BEVs are now centre stage among the options. Rutqvist points out that by replacing a diesel vehicle, the TH665B truck could reduce a mine’s carbon emissions by 1 to 2 tonnes every day.

Building on the heritage of Artisan Vehicle Systems, Sandvik’s technology is already proven and ready for market. The Sandvik TH665B truck displayed at Electra Mining Africa 2022 completed final factory trials in California earlier in the year, and will soon be in Australia for extended field trials at a leading gold producer.

There, it will haul heavy loads at speed on long and steeply inclined ramp, to push this technology to its limits, Rutqvist explains. After the site testing is finalised, it is planned that the first commercial builds can start in 2023. Other products in the range are also ready for deployment, with a deep level South African mine already in line to receive the Sandvik LH518B compact 18-tonne loader in the next few months. The company’s over-arching strategy is to have a full range offering by 2025, covering all the major size classes with battery electric trucks and loaders.

“Beyond the decarbonisation benefits of BEVs, mines are ordering them for the improved productivity they will deliver,” he says. “Electric technology can increase tonnages moved by 20 to 30% due to the higher power levels and faster cycle times. The ground-up design has ensured a simplified driveline that also lowers operating costs.”

One of the key aspects of Sandvik’s BEV offering is that it aims to ease implementation in existing mine designs – rather than requiring extensive reconfiguration of mine infrastructure. This includes the battery-swapping functionality, allowing each unit to off-load a depleted battery and on-load a full one by itself – without the operator leaving their cab. Neither does the mine have to put any extra cranes or lifting devices in place.

The leveraging of electric, automation and digital aspects are vital to the future of mining, he argues. With regard to BEVs, this means marrying Sandvik’s established AutoMine™ technology with the exciting new directions from its Artisan acquisition.

“We are planning a staged implementation of the latest Sandvik control systems on our BEVs, starting with the LH518B loader next year,” he says. “This will be the start of the process of enabling AutoMine™ on all our BEVs.”

This will further improve machine utilisation and reduce total cost of ownership, due to automation potential and end-to-end optimisation of the load and haul process. The digitalisation focus is also crucial, and includes a current focus on telemetry.

“We are fitting all our BEVs with our Sandvik Knowledge Box™ – our standard telemetry box – for gathering machine data and transmitting it to cloud storage,” he says. “This data can then be accessed in the My Sandvik IoT hub, where it is processed into easy-to-use knowledge about the fleet’s health and performance.”

With batteries now becoming a pillar of mining’s future, there is also work underway to give BEV users detailed information in real time about the health of batteries used in mining equipment. Rutqvist highlighted that the technology road ahead holds much potential for forward-looking mines, and that Sandvik is well advanced on this journey.

Adventists join call for ban on small scale mining

0

The Seventh-day Adventist Church has designated the fourth Saturday in October as Creation Sabbath.

Saturday, October 22, 2022 was marked as the Creation Sabbath, a special time to remember and affirm belief that the world and everything in it belong to God and that God expects human beings, placed on earth as rulers, to exercise benevolent, and selfless stewardship of the earth.

In a press statement, the church said, “As we mark this day therefore, the Adventist Church in Ghana condemns in no uncertain terms the blatant disregard, abuse and over-exploitation of our natural resources in the name of small scale mining (Galamsey).”

“We support the recent call by religious leaders for a ban on small scale mining (Galamsey), and demand that the perpetuators of this crime work to reclaim the lands, water bodies and forest reserves that have been destroyed by their activities. We are also of the firm belief that there are laws in this country, and until they are enforced it will be difficult for perpetrators to stop this destructive act.”

“OUR STAND IS BASED ON OUR BELIEF THAT HUMAN BEINGS WERE MANDATED TO CARE FOR THE EARTH AS RECORDED IN GENESIS 1:26 “AND GOD SAID, LET US MAKE MAN IN OUR IMAGE, AFTER OUR LIKENESS: AND LET THEM HAVE DOMINION OVER THE FISH OF THE SEA, AND OVER THE FOWL OF THE AIR, AND OVER THE CATTLE, AND OVER ALL THE EARTH, AND OVER EVERY CREEPING THING THAT CREEPETH UPON THE EARTH.”

“THE COMMAND, “TO HAVE DOMINION” IS NOT TO BE MISCONSTRUED AS A RIGHT TO ABUSE THE EARTH.

“AS WE MARK THE CREATION SABBATH TODAY, THE ADVENTIST CHURCH IN GHANA WISHES TO REMIND GHANAIANS AND CHRISTIANS ESPECIALLY OF OUR PATRIOTIC DUTY AND CHRISTIAN OBLIGATION TO PASS ON THIS EARTH AND ITS RESOURCES TO THE NEXT GENERATION IN A MANNER THAT SUPPORTS THEIR LIVELIHOOD AND SUSTENANCE OF LIFE.

“IN REVELATION 11:18, WE ARE TOLD THAT GOD WILL DESTROY THOSE WHO DESTROY THE EARTH.

“THE CHURCH APPRECIATES THE VARIOUS EFFORTS THAT HAVE BEEN SO FAR TO CREATE AWARENESS ON THE MENACE OF GALAMSEY AND THE EFFORTS BY GOVERNMENT TO PROVIDE ALTERNATIVE INCOME SOURCES FOR THOSE WHOSE LIVELIHOODS WILL BE AFFECTED BY A BAN ON SMALL SCALE MINING.

 

 

“THE ADVENTIST CHURCH, ON CREATION SABBATH, REITERATES THAT WE ARE OBLIGATED TO STUDY NATURE, LEARN FROM IT, AND PRESERVE IT FOR FUTURE GENERATIONS TO DO THE SAME, AND CALLS ON ALL GHANAIANS TO SEE THE FIGHT AGAINST GALAMSEY AS A PATRIOTIC RESPONSIBILITY AS WELL AS S A CHRISTIAN DUTY.

“SEVENTH-DAY ADVENTISTS ARE A GLOBAL FAMILY OF CHRISTIANS WHO HOLD THE BIBLE AS THE ULTIMATE AUTHORITY AND OBSERVE THE SEVENTH-DAY SABBATH.”

Bespoke pit fan motors with fin cooling

0

Menzel Elektromotoren has designed and manufactured three powerful 6600 V squirrel cage motors as integral components for pit fans. The customer specified cylindrical motor casings as compact as possible. The greatest challenge was to implement the required rated power of 1700 kW in cylindrical casings. Menzel therefore designed fin-cooled motors (cooling type IC 411) in frame size 630, an extremely unusual design for motors this large. The manufacture is complex but the result is optimal for the constricted installation conditions. In order to save additional space, all connection cables are routed out of the motors and the terminal boxes are mounted outside the fans. Since the driven fan wheels are mounted directly on the motor shafts, the motor bearing must compensate additional high loads: radial loads up to 20700 N and axial loads up to 27000 N. For the required bearing service life of 100,000 hours, Menzel implemented a special rolling bearing setup. In addition, the motors have a second shaft end for a holding brake. The three-phase squirrel cage motors are designed for operation on a frequency converter (duty type S9) with speed changes and reversal of the rotation direction. This allows the pit fans not only to ventilate the mine, but also to extract dangerous firedamp if necessary.

Nigeria to pay $496 million to settle Indian firm’s claim over Ajaokuta steel

0

The Nigerian government says it has agreed to pay $496 million to settle a multibillion dollar claim by Global Steel Holdings Limited over the control of Ajaokuta Steel Company.

Attorney-General Abubakar Malami said the federal government will pay the company $496 million instead of $5.258 billion demanded by the firm, to settle the dispute. The deal was reached under the alternative dispute resolution framework of the International Chamber of Commerce, said a statement by Mr Malami’s spokesperson, Umar Gwandu.

The dispute followed the federal government’s revocation in 2008 of an agreement that handed control of the steel works and the National Iron Ore Mining Company to Global Steel Holdings Limited, an Indian firm. In cancelling the deal, the Umar Yarádua administration said the terms of the concession at the time were not favourable to the country.

The steel company, located in Kogi State, was conceived to serve as the pillar of Nigeria’s industrialisation. It was built by the Soviets between 1979 and the mid-1990s but has never produced steel as the project was never completed. It was also mismanaged.

The government said the seeds of the disputes can be traced to five contracts entered between 1999 and 2007 that gave complete control over the Nigerian steel space to one company group, Global Steel group.

The justice ministry said the decision to terminate the contracts by a new administration in 2008 was taken contrary to legal advice by the Federal Ministry of Justice, which cited the termination cost in the form of damages. It said had the government waited for 55 days, the pact would have terminated lawfully and the government would have collected more than $26 million from Global Steel.


“This was because the firm appeared unable to pay the first tranche for the Ajaokuta shares before the first anniversary of the agreement (25 May 2008),” the statement said.

“This failure would have given Nigeria a right to over $26m as liquidated damages under cl.12 of the Ajaokuta Share Purchase Agreement.

“Global steel, in consequence, took the federal government to the International Chamber of Commerce, International Court of Arbitration, Paris, commencing arbitration in 2008. Although the Federal Government negotiated a settlement in May 2013, the previous administration failed to implement its settlement agreement,” the statement said.

In May 2020, Global Steel threatened a resumption of the arbitration and announced an anticipated claim in damages of over $10-14 billion against Nigeria.

The government said it agreed to pay over $400 million to settle the case once and for all after engaging PwCNigeria to do a comprehensive review to ensure taxpayers are protected.

With this development, the statement said President Muhammadu Buhari has now “rescued the steel industry from interminable and complex disputes as well as saving the taxpayer from humongous damages.”

“The Office of the Attorney General of the Federation and Minister of Justice grappled with the inherited problem by adopting a blueprint of seven principles for the cost-effective resolution of contractual disputes wherever they occur. They are the use of institutional mediation, choice of FGN counsel, the use of financial advisers with reputational capital, the importance of not discouraging foreign investment, fiscal responsibility, transparency, and the recognition that joined-up government produces superior outcomes,” Mr Gwandu said.

KWATANI EXPERIENCES BEST GROWTH IN ITS HISTORY

0

South African based vibrating screen and feeder original equipment manufacturer (OEM) Kwatani reports that orders for its equipment have surged in recent months to record levels, with orders coming not only from South Africa and the southern African region but also overseas markets.

 

“The current level of business is the best we’ve ever seen since the company was founded nearly 50 years ago and every month now is turning out to be a record month,” says Jan Schoepflin, General Manager Sales & Service at Kwatani. “The growth is quite astonishing – in fact, 50 to 60 %, year on year.”

 

He adds that Kwatani is currently producing around 60 machines a month. “To keep pace with demand, we’ve rented an additional 3 000 m2 of factory space to complement the 17 000 m2 we already have,” he says. “Being part of Sandvik Rock Processing Solutions, which in turn is a business area within the Sandvik Group, we’ve also been able to outsource some production to other Sandvik factories overseas, including Sandvik’s Indian factory.”

 

One of Kwatani’s current orders – won in the face of intense opposition – involves the supply of over 70 screens and associated equipment to a large copper mining operation in Central Asia. This is the largest order in Kwatani’s history and probably the largest single screen order ever to be won by a screen manufacturer based in Africa. “We’re expecting another large order from this region shortly – it won’t be quite as big but will still be very substantial,” says Schoepflin.

 

Kwatani is also busy with two big contracts in southern Africa, one for a major platinum mine in South Africa and the other for a zinc project in the DRC. Both projects are in the construction phase.

 

According to Schoepflin, the surge in sales reflects not only more buoyant conditions within the global mining industry but also Kwatani’s membership of the Sandvik Group.

 

“We became part of Sandvik at the end of 2021 and this has opened many doors to us,” he says. “We’ve always been big in Africa and were, in fact, already ranked as the biggest screen manufacturer on the continent prior to being acquired by Sandvik but were less strong in certain other parts of the world. Being part of Sandvik has given us improved access to many markets, particularly in South America where Sandvik is the dominant supplier of mining equipment.”

 

Schoepflin also points to the quality of Kwatani’s products as another reason for the skyrocketing demand for its equipment. “We produce bullet-proof products that work reliably and efficiently and that have been proven in Africa’s mining areas, which are probably the toughest in the world in terms of the demands placed on machines,” he says. “Equipment that works well in Africa will perform anywhere.”

 

He adds that the fact that Kwatani’s equipment is manufactured locally is another major plus for the company. “Our manufacturing costs here in South Africa are low by global standards and our exports also benefit from the fact that South Africa’s currency, the rand, is very weak. The result is that our machines are very competitively priced.”

 

Kwatani forms part of Sandvik’s crushing and screening division within Sandvik Rock Processing Solutions. This now includes not only Kwatani and Sandvik’s own screening business but also the recently acquired mining related business of Schenck Process Group, making Sandvik the world’s biggest supplier by far of vibrating screens and related equipment.
