9 Step Process for Discovering, Mining and 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.

Processing, smelting and refining gold World Gold Council

In cyanidation, metallic gold is oxidised and dissolved in an alkaline cyanide solution. When gold dissolution is complete, the gold-bearing solution is separated from the solids. With ores of higher gold content greater than 20 grams of gold per tonne of ore , cyanidation is accomplished by vat leaching, which involves holding a slurry of ore .
