In metallurgy, refining consists of purifying an impure metal. It is to be distinguished from other processes such as smelting and calcining in that those two involve a chemical change to the raw material, whereas in refining, the final material is usually identical chemically to the original one, only it is purer. The processes used are of many types, including pyrometallurgical and

The blast furnace works according to the counterflow principle: the stock column, made up of ore, coke and additions, slides down towards its conversion, while the top gases rise and heat the stock column. At the bottom of the furnace the iron ore is chemically reduced. The blast reacts with the coke; carbon dioxide and carbon monoxide are formed at temperatures of up to 2000 °C.
