Even after this process, the gold that is obtained is 98% pure.

Pre-Melt. Prior to actually refining it, the impure gold is melted.
Chlorination. Injected into the molten metals is Chlorine gas, which forces all metals but gold to float.
Degolding. Once the molten chloride slag has been recovered from chlorination, soda ash is added.
Electrolysis. Through this process, gold is brought to 9999 purity.
