Trafo Power Solutions shows its agility in upgrading DRC mine transformers

0

With its experience in Africa and its agility in executing projects rapidly, Trafo Power Solutions is supplying three mini-substations and two transformers to a copper-zinc mine in the Democratic Republic of Congo.

David Claassen, Managing Director of Trafo Power Solutions, says the pressure was on from early in the planning stages to ensure this critical equipment would be available on time – to facilitate the continued mine expansion. From the date of the contract award, the company will deliver the units to the mine site within just four months – despite most of South African industry taking an annual December break.

“We have conducted projects previously with the end-client and the engineering, procurement and construction (EPC) contractor, so have a good understanding of their requirements,” explains Claassen. “This experience – combined with our history in the DRC and in the mining sector – gave us the edge in expediting the whole process.”

The order was for two 2000 kVA transformers to step down the electricity supply from 6,6 kV to 550V, as well as three dry-type miniature substations. Two of the mini-substations are rated 315 kVA and 6,6 kV to 400 V, while the third is a 630 kVA unit which also steps down from 6,6 kV to 400 V

Lifecycle approach with OEM parts for sustainable pumping solutions

0

Capital equipment like pumps operate only as well as their components and wear parts allow, so it makes little sense to risk this performance by installing a replicated part.

“Mining and other industrial applications rely heavily on continuous operations to reach the productivity levels that make them profitable,” says Marnus Koorts, General Manager Pumps at Weir Minerals Africa. “This productivity is in turn the result of decades of partnership with original equipment manufacturers (OEMs) like Weir Minerals, who provide much of the technological foundation underpinning a mining operation.”

Koorts emphasises that the lifecycle cost of key equipment like pumps is many orders of magnitude higher than its upfront capital cost – as they all need a high standard of maintenance that matches the quality of their initial manufacture. As long as the equipment performs to expectation, it will contribute to the mine’s success.

OEM

“What is often not fully understood, however, is that OEM spare parts are as carefully designed and manufactured as the core equipment itself,” he explains. “As an OEM with over 150 years of field experience, we have deep insights into how our parts perform – and can confidently provide our customers with performance predictions and service intervals.”

Zambian lead poisoning Claimants win permission to appeal class action against Anglo American

0

On Friday 19 April, in a crucial step towards achieving justice for the children and women who allege lead poisoning caused by a former Anglo American lead mining operation in Kabwe, Zambia, the Johannesburg High Court granted permission to appeal an earlier judgment that dismissed certification of the class action. 

In granting permission Justice Leonie Wendell found that an appeal against her earlier judgment had ‘reasonable prospects of success on at least one ground of appeal’ and that there were ‘compelling reasons to grant the appeal, as class action law is still being developed in South Africa’, and that ‘there are current matters of law of public importance which directly implicate constitutional rights’. The Kabwe Claimants will now take their case against Anglo American South Africa (“AASA”) before the Supreme Court of Appeal of South Africa later this year. 

This is a major step forward in the longstanding lead poisoning class action claim against AASA, a wholly-owned subsidiary of London headquartered Anglo American Plc. The December judgment effectively blocked access to justice for the people of Kabwe. 

Scope of case

Kabwe was an Anglo American mine from 1925 to 1974. The evidence submitted to the court by the Claimants in support of this claim is clear. From the early 1970s, reports by the Mine doctors showed that several children had died  of lead poisoning from the mine, and a high proportion of  children in the local communities were suffering from massive blood lead levels.

How sensor-based sorting of sulfide ores can optimize the process, significantly reduce costs and environmental impact in copper, zinc and lead recovery

0

The accelerating increase in global demand for copper, zinc and lead poses a challenge for mining operations: increasing their efficiency and productivity to meet the demand while ensuring their profitability and sustainability. Sensor-based ore sorting can be an invaluable asset for optimizing the process and achieving this goal, as Rasoul Rezai, Global Segment Manager Metals at TOMRA Mining, explains.

Sulfide minerals are the source of metals such as copper, zinc and lead, which have a key role to play in our modern lifestyle – with uses ranging from the energy supply, electronics and transportation to construction and infrastructure. The increase in demand for these three metals is expected to accelerate, driven by a variety of factors, such as infrastructure development, the rising demand for electronics and, very importantly, the transition to a low carbon economy.

In fact, they are among the critical raw materials required for the electrification of the economy, moving from fossil fuels to wind and solar power generation, and battery or fuel-cell electric vehicles (EVs). Copper is an essential driver of the energy transition for its uses in electrification, including the charging infrastructure for EVs and, according to a report by the International Energy Agency, the world will need between 1.7 to 2.7 times as much copper in 2040 as it produces today.

The global zinc demand for renewable energy technologies is forecast to increase consistently to reach 364,000 metric tons in 2030, up from 109,300 in 2020, as stated in a Statista report. The value of the global market for copper and zinc is expected to reach $394 billion and $49.6 billion respectively between 2027 and 2030. The lead market is also expected to flourish, driven by the growing demand for energy storage, the accelerating adoption of EVs, and integration of smart-grid technologies.
