Gold Chlorination Process

Extraction of Gold - Element Gold, Au, Transition Metal

Bromine acts more energetically than chlorine, and has also been employed in the extraction. The recovery of the gold is effected similarly, and the bromine is then liberated by the action of chlorine, but it is impossible to prevent loss of bromine. Cyanide-process The extraction of gold by the cyanide-method is of great technical importance.

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 ...

Metalor : Refining

The characteristics of the material determine the choice of treatment after homogenization. Alloys containing a relatively high percentage of gold undergo prerefining by chlorination in the "Miller" furnace.. This pyro-metallurgical procedure performs an initial separation of gold, silver, and copper.. The resulting gold anodes will be processed further in the electrolytic cells.
