FIELD: nonferrous metallurgy. SUBSTANCE: method for processing of arsenic-containing sulfide concentrates includes pressure oxidizing leaching at high pressure of oxygen and extraction of arsenic from solid product which is effected by heating leached pulp up to temperature of not less than 1150 C. Then, granulated concentrate is separated from fine arsenic-containing fraction by screening or hydraulic classification. EFFECT: higher efficiency. 1 tbl
