What Is the Miller Process? wiseGEEK

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.

Gold Chlorination Process by Miller

2020-12-9 · 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

Miller Chlorination process Gold Refining Forum

2019-8-22 · This process is well beyond the scope of home refining. It offers risk of death --- something that should not be taken lightly. Platinum won't be eliminated very well by the Miller Process for the same reason that the gold remains pure: its chloride is not stable and will not form at that temperature, much like Pd. Rh will form a volatile
