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 ...
