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.
Gold and Platinum Refining Recovery Systems / Equipment. Miller''s Gold Chlorination process was introduced by 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.
The Miller process is an industrialscale chemical procedure used to refine gold to a high degree of purity (%). 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 ...

Describes the Miller Chlorination Process used in gold refining in all its steps and chemistry. The reactor and chemical used to obtain pure % gold bars.
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.
For the first time ever, gold processing can be done with a high level of confidence and safety, from a very small jewelry business to medium scale refinery. The process is simple and easy. By using our REFINEIT system, all the user has to do is melt the gold in an ingot, submerge the gold in the gold refining equipment we provide, then wait.
The Miller Process for Refining Gold ... Unlike the Wolhwill Process described earlier in this series the Miller Process doesn''t use electricity but rather uses a stream of chlorine gas that is passed through a crucible of molten gold that produces gold that is Fine.

Gold parting as a process was specifically invented to remove the silver. The main ancient process of gold parting was by salt cementation and there is archaeological evidence of that process from the 6th century BC in Sardis, Lydia. In the postmedieval period parting using antimony, sulfates and mineral acids was also used.
The Miller chlorine process is a refining process used to refine large amounts of gold with chlorine gas. When chlorine gas is injected into molten gold the chlorine forms chlorides with less noble metals. The chlorides can then be easily removed as they will not alloy with the gold.
An overview on how to refine precious metals. There are many kinds of materials that yield pure gold, platinum, or silver when refined. Though it''s usually a little intimidating the first time you do anything, refining precious metals yourself is relatively easy to do (even with no experience) provided you have the right information, supplies, and equipment.
Our processes enable us to refine gold up to a fineness of parts per thousand, silver up to parts per thousand and platinum and palladium to over parts per thousand. Firstclass technical equipment and knowledge ensure an excellent refining service for our Clients in .

Jun 07, 2012· Invented by Dr. Francis Bowyer Miller, the Miller Process was a game changer in the world of gold refining. It is popular among metal refiners all over the world because – in a nut shell – it''s cheap, easy, and produces highpurity gold samples – about % pure gold.
With 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. Ores
Apr 24, 2017· Used to refine gold on an industrial scale, the Miller Process, invented by Francis Bowyer Miller, is capable of refining gold to % purity. This technique includes passing chlorine gas through melted, unrefined gold, causing silver and other base metals to turn solid and float to the top from where they are skimmed off.
