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 chloridesMore
miller chlorination machine for gold. Miller process refining equipment other articles where miller process is discussed gold processing history millers process of refining impure gold with chlorine gas patented in britain in and emil wohlwills electrorefining process introduced in hamburg, ger, in,it became possible routinely to achieve higher purities than had been allowed by fire refining.More
The Wohlwill process is an electrochemical process. The Miller process produces a slightly lower purity of gold, only 99.95 percent pure.Gold Refining Plant/Machine Manufacturer (Aqua Regia .Our complete in-house gold refining systems, provide you full control over this primary and crucial process.More
The Miller process is rapid and simple, but it produces gold of only about 99.5 percent purity. The Wohlwill process increases purity to about 99.99 percent by electrolysis. In this process, a casting of impure gold is lowered into an electrolyte solution of hydrochloric acid and gold chloride.More
miller chlorination machine for gold. The Miller process uses gaseous chlorine to extract impurities when gold is at melting point impurities separate into a layer on the surface of the molten purified gold. The Miller process is rapid and simple, but it produces goldMore
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, goldMore
