FIELD: hydrometallurgy. SUBSTANCE: invention deals with processing of sulfide materials: dressing rejects, metallurgical wastes, subquality ores. Sulfide material is treated with hydrochloric acid solution in presence of sodium chloride and iron compounds. In this process selective leaching of metals is conducted with no air access in a capillary regime with fixed liquid to solids ratio, while extraction of target product is controlled taking into account corrosion requirements (1:3). Ratio of contacting components in subjected to leaching material is chosen qualitatively and quantitatively when varying their summary area inside solution. EFFECT: increased resource for metal production. 1 cl, 2 tbl, 2 dwg |
