Processing, smelting and refining gold World Gold Council
The two gold refining methods most commonly employed to derive pure gold are: the Miller process and the Wohlwill process. The Miller process uses gaseous chlorine to extract impurities when gold is at melting point impurities separate into a layer on the surface of the molten purified gold.
Gold also dissolves in alkaline solutions of cyanide, which are used in mining and electroplating. Gold dissolves in mercury, forming amalgam alloys, but this is not a chemical reaction. A relatively rare element, gold is a precious metal that has been used for coinage, jewelry, and other arts throughout recorded history.
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
