In order to extract the valuable component, be it gold, copper, uranium, or otherwise, mined ore undergoes several processing steps, often involving additives and/or chemicals. While this allows the target component to be separated out, it causes the gangue to be contaminated. Gangue material is often also contaminated as a result of reacting ...
Gold Chlorination Processes Methods
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 ...
How to Use Bleach on Gold Ore to Remove Gold | Sciencing
Apr 24, 2017 · 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.
