This process does not result in gold that is 100 percent pure, but it does eliminate the bulk of the impurities. The problem with this method is the release of the mercury vapor into the environment. Even if equipment is used to catch the vapor, some still can get into the atmosphere.
Yet mining the ore is just one stage in a long and complex gold mining process. Long before any gold can be extracted, significant exploration and development needs to take place, both to determine, as accurately as possible, the size of the deposit as well as how to extract and process the ore efficiently, safely and responsibly.
chlorination in processing gold ore offers 6361 industrial electrolyzer products. About 4% of these are water treatment, 1% are gas generation equipment. A wide variety of industrial.
Later, probably prior to 1000, it was discovered that gold adhered to mercury, and this developed into the amalgamation process that still finds a use in the treatment of gold ores. In the latter part of the 18th century and the greater part of the 19th the chlorination process was used extensively.
The Mining Process. 5. Leaching and adsorption A slurry of ground ore, water and a weak cyanide solution is fed into large steel leach tanks where the gold and silver are dissolved. Following this leaching process the slurry passes through six adsorption tanks containing carbon granules which adsorb the .
The process of wet chlorination oxidizes and solubilizes the gold and selenium in the slimes. Hydrogen peroxide is used as the oxidant and hydrochloric acid provides the chloride for gold complex solubility.
The main advantage of the Chlorination Process to dissolve gold is the high Trilogy Refining completes pilot plant testing at Sleepy Bear Mining Facility (SBM) Mojave, Ca. Trilogy starts construction on 3000lb mobile processor system.

The feasibility to recover the gold present in alluvial material, by means of a chlorination process, using chlorine as a reactive agent, has been studied.
From ore to doré. The two gold refining methods most commonly employed to derive pure gold are: the Miller process and the Wohlwill process. 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...
However, its use in mining Chlorination was the most popular process to extract gold, before it was rendered obsolete with the advent of the cyanidation of the process to preg robbing gold .
Chlorine was first used in recovery of gold from its ores in 1851 by Karl Friedrich Plattner, who used metallic iron to cement gold from the chloride leach solution (, 1881). The barrel chlorination process used chlorine gas generated with bleaching powder and sulfuric acid inside a rotating barrel.
Gold Chlorination Process by Miller. Miller's 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.

Cyanide. Several processes can then be used to separate the gold from the ore. The most common techniques in the United States use cyanide in various ways. In one, the ground ore is put into a tank containing a weak cyanide solution and zinc is added. The zinc causes a chemical reaction which separates the gold from the ore.
A gold recovery process is disclosed in which the gold content of ores, including carbonaceous ores or mixtures of carbonaceous and oxide ores, is extracted by a simultaneous chlorine leach and ion exchange resin adsorption Newbery–Vautin chlorination process is a process to extract gold from its ore using chlorination developed by James Cosmo Newbery and Claude Vautin.
