Miller process GoldRefiningWiki
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.
Miller Chlorination process Gold Refining
Jun 18, 2011· Platinum won't be eliminated very well by the Miller Process for the same reason that the gold remains pure: its chloride is not stable and will not form at that temperature, much like Pd. Rh will form a volatile trichloride at the melting point of gold.
The Refining Process Hoover and Strong
Refining To Fine Gold. These float on top of the melt and are skimmed from the surface to undergo a secondary refine to reclaim any silver. Once the process is complete, the remaining liquid metal is at least 98% pure gold. This is cast into anodes and electrolytically refined by submerging into a .
Metalor : Refining
Refining. Alloys containing a relatively high percentage of gold undergo prerefining by chlorination in the "Miller" furnace. This pyrometallurgical procedure performs an initial separation of gold, silver, and copper. The resulting gold anodes will be processed further in the electrolytic cells.
Processes Involved In Refining Gold
Miller And Wohlwill Processes Of Gold Refining. Miller process WikipediaThe resulting gold is % pure, but of lower purity than gold produced by the other common refining method, the Wohlwill process, w. Get Price. Gold extraction Wikipedia.
Gold parting Wikipedia
Gold parting. In the postmedieval period parting using antimony, sulfates and mineral acids was also used. In the modern period chlorination using the Miller process, and electrolysis using the Wohlwill process are the most widely used methods of refining gold by removing silver and platinum .
Fundamental knowledge to Raw Gold and Refining SlideShare
May 26, 2015· Two methods are commonly employed for purification: the Miller process and the Wohlwill process. The Miller process is based on the fact that virtually all the impurities present in gold combine with gaseous chlorine more readily than gold does at temperatures equal to or greater than the melting point of gold.
Refining of Gold at the Rand Refinery
THE REFINING OF GOLD are to refine bullion and recover precious metals from byproduct materials received from member gold mines and to sell the refined gold to the Reserve Bank, which credits the mines accordingly. A subsidiary function is now the production of blanks for the Krugerrand and its subdenominations.
