Evaluation of Autoclave Oxidation of Sulfide Concentrates as Applied to the Subsequent Sulfite-Thiosulfate Leaching of Noble Metals

摘要

The results of investigations into the completeness of the sulfite-thiosulfate dissolution of noble metals depending on the conditions of the autoclave opening (AO) of flotation concentrates under various leaching conditions (the reagent concentration and the influence of various additions) are described. The necessity of carrying out the AO process with the complete maximum recovery using cyanidation is shown allowing for the factors that increase the content of elemental sulfur in the AO cake.
