What happens when gold is refined?

The purpose of this refining is to remove any remaining impurities. The crude gold is melted and then treated with chloride. This converts any foreign elements or minerals still in the gold into chloride, which will then naturally drift off the gold. The result of this process is 99.5 percent pure gold.
