Sep 08, 2011· If you''re doing gold in absurd volume (5000 ozt/day), it''s cheapest to chlorinate and then electrorefine. 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.
Jan 18, 2017· Depending on the intended use of the gold, it may have to be refined before being put to use. Refining gold is simply the process of removing the finer impurities that the smelting process could not remove. There are several methods used to refine gold. The most common gold refining methods include: 1. Miller Process

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. It works to remove all the impurities because gold is least affected ...
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.
An old and wellestablished process, the Wohlwill method is widely used in major gold refineries, often in conjunction with the Miller process. (For typical jeweler''s scraps and wastes, a preliminary refining step, such as the Miller or inquartation process, is required.)
The resulting gold is % pure, and of higher purity than gold produced by the other common refining method, the Miller process, which produces gold of % purity. For industrial gold production the Wohlwill process is necessary for highest purity gold applications.
Miller process Wikipedia. The Miller process is an industrialscale chemical procedure used to refine gold to a high ... pure, but of lower purity than gold produced by the other common refining method, the Wohlwill process, which produces gold to % purity.
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.

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.
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.
