How Is Gold Refined & Processed?

According to the World Gold Council, the Miller process uses gaseous chlorine to extract impurities when gold is at its melting point. Impurities separate into a layer on the surface of the molten purified gold. While the Miller process "is rapid and simple," the Council notes, it produces gold that's only about 99.95-percent pure.

Miller process

The Miller process is an industrial-scale chemical procedure used to refine gold to a high degree of purity (99.95%). This chemical process involves blowing a stream of pure chlorine gas over and through a crucible filled with molten, but impure, gold. This process purifies the gold because nearly all other elements will form chlorides before gold and can thereby be removed as salts …
