FIELD: processing sulfide gold-and-arsenic concentrates by hydro-metallurgical methods with use of microorganisms. SUBSTANCE: proposed method includes preliminary cyanidation of initial concentrates performed before bacterial oxidation, after which bacterial oxidation is performed and cakes are prepared for cyanidation by electrochemical method and finally cyanidation is performed. EFFECT: increased extraction of noble metals; reduced duration of process; low cost of reagents. 1 dwg, 2 tbl, 1 ex |
