The Miller Process for Refining Gold. The process takes from 2 to 4 hours to complete with the chloride fumes being removed and filtered by a two stage wet filter or a two stage dry scrubbing system that maximizes the recovery of the chloride as well as the cleaning of the exhaust air from the process In the process slag is poured off the top of the melt into a crucible and allowed to …
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.

Miller process ore refining Britannica. In gold processing: History 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.
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 process was so successful that it has been adopted at all Australian Mints. Before Miller's invention, the gold coins made at the Sydney Mint were alloyed with silver, since the cost of removing this and replacing it by copper …
miller process gold refining machine grinding mill china. miller process gold refining manufacturer miller process gold refining equipment This process is known as the Wohlwill process The Miller chlorination process is an economical refining process that separates gold of about 995% purity, which can then be electro-refined to improve purity to 99999% Silver - …
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.
Used to refine gold on an industrial scale, the Miller Process, invented by Francis Bowyer Miller, is capable of refining gold to 9995 purity This technique includes passing chlorine gas through melted, unrefined gold, causing silver and other base metals to turn solid and float to,...
