Gold Chlorination Processes & Methods

2016-8-31  Chlorination Process for Gold. This process was based on the fact that chlorine, in the presence of moisture, converts gold into the trichloride AuCl3,which is soluble in water and removed by washing, the gold being then precipitated by ferrous sulphate, sulphur dioxide, hydrogen sulphide, or charcoal. Coarse gold requires long contact and should be removed by amalgamation.

Gold Chlorination Process by Miller

2021-4-28  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.
