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.
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 ...
Gold Refining Methods, Wohlwill process, Miller pr.

For refining, gold bearing alloys are processed on different methods, depending on their carat content. Two methods are commonly employed for purifiion: the Miller process and the Wohlwill process. Alternatively, it can be a complex mix of burning, drying, grinding, screening, blending and sampling for lowgrade scrap and floor sweepings.
