20-7-2020 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.

Other articles where Miller process is discussed: gold processing: History: 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.
Miller process - Wikipedia
The Miller process is an industrial-scale stone procedure used to refine gold to a high degree of purity (99.5%). It was invented by Francis Bowyer Miller (patented 1867). This stone 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 ...

Miller Gold Refining Process By Chlorination. 2020-6-17In order to purify gold and remove the silver from it by any process analogous to the cementation with nitre or salt in a reasonable time the alloy must be in such a fine state of division that the silver will be removed almost instantly or diffusion must be assisted by actually keeping the alloy in a molten state.

Gold Chlorination Process by Miller
Miller’s Gold Chlorination process was introduced by F.B. Miller. The refining process employs chlorine gas, which passed into molten gold covered with a layer of borax and silica, and reacts with most of metals present in the molten charge. Platinum group metals do not react. Basically, gold is slightly attacked in the first moments and all the chlorides formed rise to the surface and are ...
