START WITH CHUTE DESIGN TO REDUCE DUST, SAYS WEBA

0

Many industrial facilities, mines and power stations rely too much on dust suppression and extraction systems, when the real answer is to improve the flow of material through well designed chutes.

 

This is the considered opinion of Weba Chute Systems technical director Alwin Nienaber, based on decades of experience in this field. His view is that 50% to 80% of the dust problem around conveyors and transfer points can be resolved by applying the right chute system design and positioning equipment correctly.

 

“Many of the dust suppression and dust extraction systems that are applied in these applications are expected to do more than they are capable of,” says Nienaber. “A preferable approach is to get the chute design right first, and then apply these other systems to deal with the residual dust load.”

 

He explains that the advantages of doing this extend well beyond the health and safety benefits. He has seen more than a few situations where the dust created by a poorly designed chute can prevent personnel from moving or working in that area. This often prevents the checking or maintenance of critical equipment during operating hours, requiring more downtime to wait – literally – for the dust to settle.

 

“In examples like this, excessive dust can reduce an operation’s efficiency, so there is an opportunity to improve overall productivity by fixing the dust problem,” he says. “Other equipment in these areas also gets heavily coated with dust, and needs regular cleaning to ensure optimal performance. Cleaning becomes yet another avoidable cost.”

 

To address excessive dust creation, a good chute design is based on understanding the physics of material flow – and avoiding uncontrolled velocity and impact. A lack of control over the way material flows will degrade the material and create higher levels of aeration – which is what leads to dust dispersal.

 

“Our philosophy at Weba Chute Systems is to ensure that material flows more easily and remains consolidated as a homogenous stream,” he explains. “We base our designs on the ‘supertube’ effect, which also allows the controlled transfer of material onto the conveyor belt. Not only does this reduce dust, but it also cuts down on the wear rate of the belt itself.”

Kavango Resources restarts drill programme

0

Kavango Resources PLC (LSE:KAV, OTC:KVGOF) has told investors that drilling is about to restart on the company’s Kalahari Copper Belt (KCB) project area following a scheduled summer break.

Drilling will resume to complete the sixth and final hole in the programme, rounding off a total of 1,640 metres of drilling across all the holes.

The remaining hole, KCBRD006, is targeting a major stratigraphic structure identified by its Controlled-Source Audio MagnetoTelluric (CSAMT) surveying.

“Through our innovative use of CSAMT, Kavango has identified major structures for the first time on our KCB licences,” Kavango chief executive Ben Turney said in a statement.

“Our ongoing drill programme has subsequently confirmed these to be associated with deformation, fluid flow, and alteration. This could be a game changer in exploration for a new generation of drill targets on the KCB.

“Given the large size of our KCB licence package, Kavango is currently working to optimise and prioritise these. Our COO Brett Grist is presently in Botswana with our senior consultants, the results of which work are expected to refine our 2023 KCB exploration strategy”, he added.

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.”
