DMR > Mineral Policy & Promotion > Beneficiation Economics

Mineral beneficiation in South Africa. The concept of beneficiation is not new in South Africa, but it took major steps forward during the 1990s. During this period, the South African mining sector changed from being a predominantly primary commodity exporter to becoming a world exporter of processed minerals. South Africa, for example ...

microbes. The role of the bacteria is the fur-ther oxidation of the ore, but also the regeneration of the chemical oxidant Fe3+ from Fe2+. For ex-ample, bacteria catalyse the break-down of the mineral pyrite (FeS2) by oxidising the sulfur and metal (in this case ferrous iron, (Fe2+)) using oxygen. This yields solu-bleproducts that can be further
