Dec 16, 2018· 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.
Miller's process of refining impure gold with chlorine gas (patented in Britain in 1867) and Emil Wohlwill's electrorefining process (introduced in Hamburg, Ger., in 1878), it became possible routinely to achieve higher purities than had been allowed by fire refining.

The Miller chlorine process is a refining process used to refine large amounts of gold with chlorine gas. When chlorine gas is injected into molten gold the chlorine forms chlorides with less noble metals. The chlorides can then be easily removed as they will not alloy with the gold.
