Gold Chlorination Processes Methods

2016-8-31  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 ...

Chlorination process for removing precious metals from

Ground ore and primary leach solutions are ideally combined at a temperature of 80°-85° C. The leach solution has a pH of 4-6. Although the primary leach solution will extract precious metals from the ore at lower and higher temperatures, the chlorination leach process does not appear to function as efficiently at these temperature extremes.
