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.

Gold processing - Mining, Concentrating, Refining: The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade (e.g., 3 to 10 parts per million) that extensive mineral processing cannot economically be justified. In this case they are merely shattered by explosives and then …
