Copper Sulfide Pyrometallurgy

Jan 01 2008 A basic principle of many processes for extracting copper and nickel from sulfide 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 oxidizes and as a result partitions to the slag phase while some of the sulfur is carried off as sulfur dioxide
