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.

Refining Gold . Smelting is not always the final stage in gold extraction. Depending on the intended use of the gold, it may have to be refined before being put to use. Refining gold is simply the process of removing the finer impurities that the smelting process could not remove. There are several methods used to refine gold.
Another large-scale gold refining technique, the Wohlwill Process refines gold to 99.999% purity — the highest purity possible. Developed by Emil Wohlwill in 1987, this electrochemical process uses a 95% pure gold bar as an anode and small sheets of pure, 24-karat gold as the cathode.
Gold usually exists in nature in combination with other rocks and minerals. Some of these, such as silver and copper, may also be precious or semi-precious, but a variety of base metals are usually also present. Though several different techniques exist, any process used to separate metal from impurities or unwanted material is called refining.
