Abstract

PURPOSE: To reduce a metal sulfide directly to a metal by heating a sulfide, e.g., of Ni, Co, Cu, etc., together with CaO and a Na salt in a nonreductive gas.
CONSTITUTION: A metal sulfide powder, e.g., of Ni, Co, Cu, etc., in the form of pyrite, mat, etc., is mixed with a carbonaceous reducing agent and CaO, and then the mixture is heated so as to directly reduce the metal sulfide to metal through a reaction of the formula MeS+CaO+1/2C⇆Me+CaS+1/2O2. In this case, coal or coke as a reducing agent is used more than 1.2 times the theoretical amount of the said formula, a substance capable of generating CaO, e.g., CaCO3, Ca(OH)2, etc, is added more than 1.2 times (as CaO) the theoretical amount of said formula, and a Na salt in the form of carbonate, sulfate, halide, etc., is added in 0.5pts.wt. or more (as Na2O) per 100pts.wt. of the metal sulfide. Said reaction is advanced by heating the reaction system to 750°C or higher in a nonreductive gas atmosphere, e.g., combustion exhaust gas in order to reduce the metal sulfide to metal.
