Gold Ore Chlorination Mineral Processing Metallurgy Experience has shown how difficult it is to obtain information regarding laboratorytests in connection with the gold ore chlorination process for the extraction of gold from its ores and I therefore present the following method somewhat in detail for the benefit of those who may desire to
Millers 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. 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
