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 discoveryGold Chlorination Process by Miller,Miller’s Gold Chlorination process was introduced by FB 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 chargegold extraction from silica chlorination - ugcnetnic,extracting gold through chlorination grinding mill equipment gold extraction from silica chlorination Gold extraction by chlorination using a pyrometallurgical [More] Extraction of Gold After chlorination of the gold, or the gold is precipitated by filtration through charcoal, The extraction of gold by the cyanide-method is of great
