Before revision: Pyrite leaching (FeS2): In the first step, disulfide is spontaneously oxidized to thiosulfate by ferric ion (Fe3+), which in turn is reduced to give ferrous ion (Fe2+): (1) spontaneous The ferrous ion is then oxidized by bacteria using oxygen: (2) (iron oxidizers) Thiosulfate is also oxidized by bacteria to give sulfate: (3) (sulfur oxidizers) The ferric ion produced in reaction (2) oxidized more sulfide as in reaction (1), closing the cycle and given the net reaction: (4) The net products of the reaction are soluble ferrous sulfate and sulfuric acid.
