9.05.3.4.4 Impact of bacteria on the rate of sulfide-mineral oxidation. The chemical oxidation of metal sulfides is controlled in part by the dissolution of sulfide minerals under acidic conditions and by the presence of oxidants (DO, Fe 3+) that lead to the disruption of sulfide chemical bonds. Bacteria can have a significant effect on the ...
