Sep 26, 2015· chlorine solution passes through it, takes the gold to itself; and upon the charcoal being burned away, say in an iron pot, the pure gold remains. This, then, is the chlorination process, which, we think, our readers- even those quite unacquainted with chemistry- will clearly comprehend. Whether this process, admirable as it is in many cases,
extracting gold through chlorination - corsigratuitinapoli.it. A process for treating a particulated gold bearing ore to recover the gold therein is disclosed. The process includes roasting the ore to remove sulfides as sulfur dioxide followed by chlorination …

Plattner process, gold was dissolved into chlorine water (i.e., water saturated by chlorine gas) while bromine water was also mentioned. It was the first hydro-metallurgical process to recover gold.9 Svistunov et al., studying the action of chlorine water onto gold…
An average gold extraction yield of 94.9% was achieved at the outlet of the chlorination reactor with full environmental control over the residues and atmospheric emissions. The gold deposition yield was over 99.5%, leading to an overall gold extraction yield of 93.6% through …
gold ores, and the use of the chlorination process after the 1870s to improve the extraction rate of the gold from the ore. The validity of the comment by Jan Todd on the lack of knowledge in Australia about chemical extraction processes and chlorination will be assessed as part of this discussion. Calcination

Through implementing multiple-step Six Sigma tools in processing of the copper anode slimes and the technology development of in-line, intelligent ORP measurement in the wet chlorination operation, the refinery has enhanced its productivity, produces higher quality copper, gold and other metals, and increased its profitability.
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. This was the first commercial method used for gold extraction.

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 procedure. The process eliminates or reduces the degree of oxygenation and cyanidation required to conduct a standard gold extraction process.
Mar 26, 2008· Chlorination has been an important process step in the extraction of many nonferrous metals from their ores and concentrates. Some of the important chlorinating agents are gaseous chlorine…
