    OverviewSee also

    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

    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

    Mar 08, 2020· If you're doing gold in absurd volume (5000 ozt/day), it's cheapest to chlorinate and then electro-refine. You'll also need to set up a silver cell to recover the silver and the gold that reports in the silver chloride during the Miller process. Don't forget the baghouse and scrubber. You'll need a way to control waste and also mitigate fumes.

  • 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
