A pyrometallurgical chlorination process, the Miller process is one of the oldest and most widely used processes in large scale gold refining. It involves bubbling chlorine gas through molten bullion. The base metals and silver are removed as chlorides, which either volatilize or form a molten slag on the surface of the melt. The process is complete when purple fumes of gold chloride start to ...

The Miller process is a gold refining process that produces gold of approximately 99.95% purity, sufficient for many applications. It is faster and less costly than other refining options used to produce purer gold, which makes it a popular choice at some refineries. This technique involves passing chlorine gas through molten told to trigger a chemical reaction that separates impurities. If a

The Miller process is an industrial-scale chemical procedure used to refine gold to a high degree of purity (99.5%). 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 ...
