摘要

1. A process OSAZHTSENIYA sulfides HEAVY METALS -Color z acidic iron-containing solutions and slurries comprising autoclaving the starting material under pressurized hydrogen-containing gas under heating in the presence of and to ser1Y bavki followed nscheleniem X) sazhdennE ac sulfide and sulfur in the concentrate, of Whitlock and the fact that, with. simplifying the process and increasing its productivity and quality of the concentrate, the oxidation with hydrogen-containing gas is carried out at a temperature above the melting point of sulfur with the supply of an electronegative metal to the ratio of ferrous silver relative to the hydrogen chloride to the trivalent 20-292 in the solution of bivalent iron 320 mV. 2. A method according to Claim 1, characterized in that, in order to reduce the overpressure of the hydrogen-containing gas, as the electronegative metal use atosl MI1SHY. c. 3. The method of Clause 1, distinguishing between u and in order to prevent the formation of serosulphate melts and increase the quality of the co-concentrate, precipitation is carried out in the presence of F1 water-soluble metal chloride salts. with g
