Newbery–Vautin chlorination process - Wikipedia

The Newbery–Vautin chlorination process is a process to extract gold from its ore using chlorination developed by James Cosmo Newbery and Claude Vautin.. Background. The process of extracting gold from ores by absorption of the precious metal in chlorine gas, from which it is reduced to a metallic state, is not a very new discovery.

How to Leach Gold Ore With Chlorination | Sciencing

Apr 25, 2017· How to Leach Gold Ore With Chlorination ... Aerating the mixture speeds up the leaching process, because it adds oxygen. Continue to agitate the bucket until the ORP meter drops to 400. Keep the ORP meter around 1,000, but do not let it drop below 400. The HCL is a chemical that steals electrons from the substances it is mixed with.

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.

Miller process - Wikipedia

The Miller process is an industrial-scale chemical procedure used to refine gold to a high degree of purity (99.95%). 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 ...
