    09-02-2012· In the process slag is poured off the top of the melt into a crucible and allowed to slowly cool so any gold that has been caught up with the chlorides will settle to the bottom where it can be recovered as a button of gold when the crucible has cooled completely; it is then added to the remaining molten gold. In this process the particles of gold remaining in the crucible are carefully removed by

    miller process gold refining machines

    miller process gold refining equipment. Gold Chlorination Process by Miller 911 Metallurgist. Mar 17, 2017 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.

    Miller process Wikipedia

    The Miller process is an industrial-scale chemical procedure used to refine gold to a high degree of purity (99.5%). It was invented by Francis Bowyer Miller (patented 1867). This chemical 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 before gold does, and they can then be removed as salts that are insoluble in the molten metal.

    Processing, smelting and refining gold World Gold Council

    15-05-2021· 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. The Miller process is rapid and simple, but it produces gold of only about 99.5 percent
