9 Step Process for Discovering, Mining Refining Gold
Once basic processing is done, the ore is taken to a refinery where the remaining impurities are stripped out. Crude gold is melted and treated with chloride, which converts any remaining foreign metals to chloride which will then drift off the gold. The result is % pure gold, which is then cast into electrodes (.known as anodes) where it is then placed into an electrolytic cell. A current is then passed through .
