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

The divergent role of microbes in the field of mineral processing starting from mining and beneficiation to efficient waste disposal has been well recognized now. The roles of various microorganisms and bioreagents in the beneficiation of minerals are illustrated in this paper.
