METHOD FOR CONTINUOUSLY CONVERTING NICKEL-CONTAINING COPPER SULPHIDE MATERIALS

null null A method of continuously processing nickel-containing copper sulphide materials into blister copper, waste slag, and copper-nickel alloy includes oxidizing smelting along with SiO2 and CaO-containing fluxes and coal in a conversion furnace for conversion to produce blister copper, gases with concentration of SO2, and slag with an SiO2:CaO concentration ratio of 0.4:1 to 3:1, in which the sum of the iron, nickel, and cobalt is not more than 30 wt. %, at a specific oxygen consumption in the range of 150-240 Nm3 per ton of dry sulphide material, and depleting the slag in a separate reduction furnace, using a mixture of an oxygen-containing gas and a hydrocarbon fuel at an oxygen consumption coefficient (α) in a range of 0.5 to 0.9, while supplying coal in an amount of up to 15% of weight of the slag produced by the oxidizing smelting, to produce a waste slag and a copper-nickel alloy.
