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.
Miller process gold refining equipment 09082019 the miller process is a gold refining process that produces gold of approximately 9995 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 Gold Refining Process by Chlorination Miller Chlorination Process In 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 ...
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 ...

Used to refine gold on an industrial scale, the Miller Process, invented by Francis Bowyer Miller, is capable of refining gold to 99.95% purity. This technique includes passing chlorine gas through melted, unrefined gold, causing silver and other base metals to turn solid and float to the top from where they are skimmed off.
