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 ...

Cupellation Process - Gold Refining Machine

In the traditional cupellation process for gold and silver, the amount of silver in the gold obtained is very important. A good clean separation is difficult to achieve, as gold protects silver from attack. Therefore, the amount of silver should be sufficient. If it is less, 99.99% pure silver should be added which is called quartation.

The resulting 995 fine gold is poured into an anode mould. 3. Degolding. Soda ash is added to the molten chloride slag recovered from chlorination. The reaction causes gold particles to collect in a silver-gold alloy 'button' that settles at the bottom of the crucible. 4. Electrolysis. This process brings gold to 9999 purity.
