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.

2020-12-01  In short, the gold refining process calculates the amount of pure gold and alloy metals. Karat is a measurement unit to indicate how much pure gold is present in an alloy. For instance, 24-karat gold indicates pure gold, and 18-karat gold indicates 18 parts of pure gold and 6 parts of another alloy. Gold is not available in its purest form.
