The final stage of gold production refining involves removing impurities that remain after the smelting companies receive doré bars, as well as scrap gold, and reliquefy the metal in a furnace. Workers add borax and soda ash to the molten metal, which separates the pure gold from other precious and less precious metals.
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 Refining and Value Addition Minataur gold refinery The Minataur™ refining technology is a unique all hydrometallurgical route, based on solvent extraction, for refining gold to a purity of "five nines" ( per cent). Compared with conventional smelting and electro refining technology, the Minataur process offers:

Electrowinning is the oldest industrial electrolytic process. The English chemist Humphry Davy obtained sodium metal in elemental form for the first time in 1807 by the electrolysis of molten sodium hydroxide.. Electrorefining of copper was first demonstrated experimentally by Maximilian, Duke of Leuchtenberg in .
The diagram gives an overview of the key processes involved in the refining of gold and silver. Please note that this is highly simplified and does not detail the many subprocesses involved within each key process, the chemical inputs involved in each process, as well how the waste outputs from each process are handled.
