The transformation of galena and other lead-sulfur compounds in the supergene zone begins, according to classic concepts, with oxidation under aqueous-aerobic conditions and ends with the formation of the lead sulfate anglesite. This article considers the microbiological processes of lead-mineral transformation that occur to one degree or another in the oxide zone of ore deposits and the results of previous experiments in the alteration of lead minerals by microorganisms, as well as the new experimental material on the formation of lead dioxide. Thiobacillus ferrooxidans is an autotrophic organism requiring no organic substances; it obtains energy from the oxidation of the ferrous iron and sulfur in sulfide minerals under acidic conditions. Experiments are also described with sulfate-reducing bacteria. 12 references, 1 figure, 1 table.
