Gold And Silver Refining Explained Perth Mint. Miners will then either sell this pure gold and silver for cash or request a loco swap The dor 233 bar then becomes the property of the refiner The dor 233 bar first goes through a chlorine refining process also known as the Miller process originally developed at the Sydney Mint by Francis Bowyer Miller see Australian Dictionary of
Other articles where Miller process is discussed: gold processing: History: Millers process of refining impure gold with chlorine gas (patented in Britain in 1867) and Emil Wohlwills electrorefining process (introduced in Hamburg, Ger., in 1878), it became possible routinely to achieve higher purities than had been allowed by fire refining.
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

The Miller process is an industrialscale chemical procedure used to refine gold to a high degree of purity (%). It was invented by Francis Bowyer Miller (patented 1867). 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
