  • Miller Gold Refining Process by Chlorination

    The pot is lifted out, the button allowed to settle and solidify, when the chlorides are poured into a mould 12 by 10 by 2 inches. The silvery button obtained contains from 40 to 60 per cent, of gold. The gold in bars and in the buttons contain 99.85 per cent, of the gold issued for refining, the balance being practically in the pot. The

  • Miller process ore refining Britannica

    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.

  • 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

  • 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 before gold does, and they can then be removed as salts that are insoluble in the molten metal.

    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. Get Price. Gold parting Wikipedia. History Early history. The very earliest attempts at refining gold can be shown by the surface enhancement of gold rings. Gold quality was increased at the surface by 80–95% gold compared

  • What Is the Miller Process? wiseGEEK

    11/05/2020· 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. This technique involves passing chlorine gas through molten told to trigger a stone reaction that separates impurities. If a

  • Precious Metal Refining Process The Perth Mint

    The dore bar first goes through a chlorine refining process, also known as the Miller process. This involves bubbling chlorine gas through the molten dore metal in which the silver (and most other metals) react with the chlorine to form silver chloride as a slag on top. This process produces gold to a purity of 99.5%, which is usually cast directly into odd weight 400oz bars used in the
