Abstract

Results are reported from a study of the effect of the antimonate content of sulfides on oxidation activity, pH, and oxidation-reduction potential (E h ) in bacterial oxidation. A comparison is made between the bacterial-oxidation parameters of selective arsenic and antimony concentrates and a collective sulfide concentrate. The study results show that the kinetics of bacterial oxidation of the arsenic concentrate can be improved significantly by performing flotation in accordance with a new flow scheme that extracts antimonate from gold-bearing sulfide ore as a separate concentrate.
