A solar power generating facility recently developed by a South African gold mine has made use of Zest WEG’s locally manufactured transformers to serve this specialised application. Factors like harmonics or ‘noise’ in the current flow mean that solar photovoltaic (PV) applications require specialised transformers, explains Rynard Potgieter, Sales Manager for transformers at Zest WEG. At this site, where 40 MW of renewable energy is being generated, the company supplied 10 of i...

The careful alignment of screens and crushers in processing makes for optimal throughput and efficiency, by ensuring that all settings and parameters are ideally matched. “The Kwatani product can now give their vibrating screen customers added benefits in this regard, being part of the global Sandvik group – which is well known for its crushing solutions,” says Kenny Mayhew-Ridgers, Regional Business Director at Sandvik Rock Processing Solutions South Africa. “The advanta...

Although Gauteng dwellers have tended to dismiss wind as a renewable energy provider from this region, some are now being blown away by the gusts that puff across our far-stretching gold reef. “I thought the wind didn’t blow up here,” interim Gold Fields CEO Martin Preece confessed this week during question time at the Johannesburg- and New York-listed company's environmental social and governance (ESG) presentation.

Beginning in the early 1970s, the Canadian government said guys, we're losing ground in exploration investment. We don't seem to be attracting any of that cash. Let's introduce something that attracts money to the sector and they sat around the table and some really clever tax guys came up with the flow-through shares concept. A flow-through share is a type of common share that permits the initial purchaser to claim a tax deduction equal to the amount invested. The flow-throu...

Global climate change issues and environmental, social and governance pressures continue to attract significant attention, not least regarding the impact of coal on the environment. Some investors are divesting from companies involved in fossil fuel extraction, including banks and other funding institutions, which are increasingly limiting access to finance for the development of new coal-fired power stations and thermal coal mines. Many governments have pledged to reduce greenhouse-gas emission...

Mining luminary of South Africa’s shaft-sinking boom period at the beginning of the millennium Nigel Townshend is back in action as the newly appointed nonexecutive chairperson of United Mining Services (UMS) Limited. Since the start of this month, Townshend has been at the top table of UMS, an underground mining and metallurgical processing solutions company.

The R105-billion investment pledge by Hive Hydrogen at President Cyril Ramaphosa’s fifth South Africa Investment Conference was the biggest by far, resulting in Engineering News & Mining Weekly pursuing more information on it, only to find that the initial R105-billion is only Phase 1. Remarkably, even 50 more R105-billion Hive Hydrogen projects would be far from sufficient to meet current demand projections for the green hydrogen-derived green ammonia product that Hive Hydrogen will s...

Platinum group metals- (PGM-) based proton exchange membrane (PEM) electrolysis is a competitive technology in upscale mode and is making its mark in electrolysis for hydrogen production as well as in the use of hydrogen for vehicle mobility. PEM electrolysers have distinct advantages when dealing with renewable energy sources because they can react more dynamically and more quickly to certain on-off scenarios.

The lack of public sector transparency and emerging private sector silence from companies opting not to list are combining to limit South Africa’s knowledge of the mining sector, and thus curb its growth prospects, Mining Weekly can today report. Public sector opacity and private sector delisting without relisting, is leaving a worryingly high number of promising assets in seeming limbo.
