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. The Miller process is rapid and simple, but it ...

Gold Plating - an overview ScienceDirect Topics

The plating process starts with a gold strike treatment to prevent the exchange reaction. The same strike bath can be used for the first rinse after the gold plating. The current density depends a lot on the processing method; that is, 0.2–0.4 Adm −2 is used for barrel plating and 0.5–1 Adm −2 for rack plating.
