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

Miller process Wikipedia

The Miller process is an industrial-scale chemical procedure used to refine gold to a high degree of purity (99.5%). It was invented by Francis Bowyer Miller (patented 1867). This chemical process involves blowing a stream of pure chlorine gas over and through a crucible filled with molten, but impure, gold. This process purifies the gold because nearly all other elements will form chlorides

How to Use Bleach on Gold Ore to Remove Gold Sciencing

Gold is an almost non-reactive metal, but halogens — chlorine, bromine, fluorine and iodine — can dissolve it. Chlorine is the cheapest and lightest product that can achieve this. Bleach is the chemical compound sodium hypochlorite. When combined with hydrochloric acid, the mixture produces chlorine that dissolves gold from gold ore.

Gold processing Britannica

With E.B. 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

Gold processing Refining Britannica

Refining. Gold extracted by amalgamation or cyanidation contains a variety of impurities, including zinc, copper, silver, and iron. 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
