METHOD FOR CONTINUOUSLY CONVERTING NICKEL-CONTAINING COPPER SULPHIDE MATERIALS

The present method can be used for converting nickel-containing copper sulphide materials. A method for continuously converting nickel-containing copper sulphide materials into blister copper, waste slag and a copper-nickel alloy includes smelting the materials together with SiO2 and CaO-containing fluxes and coal in a Vanyukov converting furnace to produce blister copper, gases with a high concentration of SO2, and slag with an SiO2/ CaO concentration ratio of from 3:1 to 1:1, in which the sum of the iron, nickel and cobalt concentrations is not more than 30 wt%,at a specific oxygen consumption in the range of 150-240 nm3 per ton of dry sulphide material for conversion, and depleting the slag in a separate unit, namely a Vanyukov reduction furnace, using a mixture of an oxygen-containinggas and a hydrocarbon fuel at an oxygen consumption coefficient (alpha) in a range of from 0.5 to 0.9, together with coal, to produce waste slag and a copper-nickel alloy. The technical result is theproduction of blister copp
