23.2: Principles of Extractive Metallurgy

The oldest, and still the most common smelting process for oxide ores involves heating them in the presence of carbon. Originally, charcoal was used, but industrial-scale smelting uses coke, a crude form of carbon prepared by pyrolysis (heating) of coal. The basic reactions are: [MO + C rightleftharpoons M + CO label{2.1}]

Roasting of Sulfide Minerals

Where more than one metal sulfide is present in the concentrate, the reactions are truly complex and very large in number. The composition of a product in sulfide roasting depends not only on the chemical and mineralogical composition of the concentrate, temperature, and partial pressures of O 2, SO 2, and SO 3 but also on the …
