Leveraging a variety of advanced solid-liquid separation technologies, the mineral processing industry in South Africa efficiently separates solid particles from liquid streams to enhance product quality and reduce …
The mineral wealth of South Africa has been exploited by Homo sapiens for at least 40,000 years and has provided many and varied commodities including gold, platinum and diamonds. This chapter provides a historical perspective on minerals and mining mainly in South Africa, although it does occasionally stray across the borders into neighbouring countries.
Need is the biggest driver of innovation in mineral processing. Fostering a culture of innovation in mineral processing in Australia. Australia has had a strong focus on primary industry over the past 200 or more years. An important part of this has been the mining and processing of minerals for ultimate metal production (mostly overseas).
Mining and processing of minerals also result in occupational exposure to toxic substances such as platinum, chromium, vanadium, manganese, mercury, cyanide and diesel particulate. South Africa has set occupational exposure limits (OELs) for some hazards, but mine workers are still at a risk.
