  • Refining (metallurgy)

    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
