Abstract

A thermodynamic evaluation of the oxidation of sulfides of heavy non-ferrous metals is carried out. It is shown that, according to the values of the decreasing Gibbs energy for these reactions, the sulfides are arranged in the following series: FeS, Ni3S2, CoS, NiS, ZnS, PbS, CdS, CuS, Cu2 S. The thermodynamic probability that all stages of the chain mechanism of oxidation of sulfides will proceed with the isolation of gaseous oxygen and atomic sulfur is also evaluated.
