A basic principle of many processes for extracting copper and nickel from sulphide ores is to overlay the molten ore or matte with a limesilicairon oxide slag and blow with air or oxygen. Some of the iron present in the ore oxidises and as a result partitions to the slag phase while some of the sulphur is carried off as sulphur dioxide
