Bioleaching - Wikipedia

This step is entirely independent of microbes. The role of the bacteria is the further oxidation of the ore, but also the regeneration of the chemical oxidant Fe 3+ from Fe 2+. For example, bacteria catalyse the breakdown of the mineral pyrite (FeS 2) by oxidising the sulfur and metal (in this case ferrous iron, (Fe 2+)) using oxygen.
