Gold Chlorination Processes Amp Methods 911 Metallurgist

Aug 31, 2016 Chlorination Process for Gold. This process was based on the fact that chlorine, in the presence of moisture, converts gold into the trichloride AuCl3 , which is soluble in water and removed by washing, the gold being then precipitated by ferrous sulphate, sulphur dioxide, hydrogen sulphide, or charcoal. Coarse gold requires long contact and ...

Advances In Gold And Silver Processing

More than a century ago, gold ores were treated by roasting and subsequent leaching with aqueous solution of chlorine. Ross 1902 reported that chlorine consumption was 3 - 10 kilograms per tonne of ore and the gold extraction was 90 - 98 per cent MacArthur and Forrest introduced the cyanidation process in 1887. Cyanide

How To Use Bleach On Gold Ore To Remove Gold Sciencing

Apr 24, 2017 Gold is an almost non-reactive metal, but halogens chlorine, bromine, fluorine and iodine can dissolve it. 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.
