COPPER - NICKEL SULFIDE CONCENTRATE PROCESSING METHOD Russian patent published in 2005 - IPC

Abstract RU 2255996 C1

FIELD: pyro - metallurgical processes in non-ferrous metallurgy.

SUBSTANCE: method comprises steps of melting copper-nickel sulfide concentrates in double-zone furnace with common sulfide bath for enriched matte; in melting zone melting concentrates with use of oxygen-containing raw blast and in reducing zone depleting slag by means of gaseous (liquid) and solid reducing agent. It provides enriched matte of desired composition and slag with metal content corresponding to that of tails.

EFFECT: simplified process for producing target- composition products.
