Pyrometallurgy of copper–nickel–iron sulphide ores: the
01/01/2008 II.13 Pyrometallurgy of copper–nickel–iron sulphide A basic principle of many processes for extracting copper and nickel from sulphide ores is to overlay the molten ore or matte with a lime–silica–iron 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
Pyrometallurgy
Roasting consists of thermal gas–solid reactions, which can include oxidation, reduction, chlorination, sulfation, and pyrohydrolysis. The most common example of roasting is the oxidation of metal sulfide ores. The metal sulfide is heated in the presence of air to a temperature that allows the oxygen in the air to react with the sulfide to form sulfur dioxide gas and solid metal oxide. The solid product from roasting is often
