Beschreibung
Zusammenfassung:	nonferrous metallurgy, particularly, methods of processing of residues of nickel carbonyl production synthesis. SUBSTANCE: method includes material degassing, leaching of nonferrous metals and iron with sulfuric acid solutions, separation of leaching residues, and its liquid phase sulfation to obtain concentrate of platinum metals as distinguished from prototype. Synthesis residues are degassed by sulfation roasting at temperature of 450-650 C for 2-6 h. Roasting cinder is ground and subjected to oxidizing leaching at atmospheric pressure. Obtained residue of leaching is sized. Provision is made for processing of residues of synthesis nonuniform in granulometric and chemical composition, obtaining of nonferrous metal solutions suitable for further processing by sulfate procedure and quality concentrate of platinum metals. EFFECT: higher efficiency. 2 cl, 1 dwg, 1 tbl, 2 ex
