FIELD: processing of sulfide ores concentrates containing nonferrous and noble metals. SUBSTANCE: utilization of oxide of tetravalent sulfur produced in roasting of concentrates of nonferrous and noble metal ores is effected by oxidation it to oxide of hexavalent sulfur with the help of hydrogen peroxide. Formed sulfuric acid is used for leaching of nonferrous metals from cinders. Noble metals remaining in cinders are recovered by cyaniding. One part of newly formed sulfuric acid is directed for regeneration of alkali metal cyanide used for leaching of nobble metals by acid displacement of hydrogen cyanide from tailing cyanide solutions and its passage through solution of alkali metal hydroxide. Method ensures technological, economic and ecological process efficiency. EFFECT: higher efficiency. 1 cl, 1 dwg
