    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. The final step is to cast the gold into electrodes or anodes and place them in

    How Is Gold Processed

    Mar 29 2020 Gold is processed by cyanide milling a chemical procedure that separates 95 to 98 percent of the gold from raw mined ore. It is then refined to the gold standard purity according to Mineweb. Heap leaching is a less expensive method of gold extraction but it is a longer process and it recovers less gold than the cyanide milling process

    The gold was concentrated by washing away the lighter river sands with water leaving behind the dense gold particles which could then be further concentrated by melting. By 2000 bc the process of purifying gold-silver alloys with salt to remove the silver was developed. The mining of alluvial deposits and later lode or vein deposits required crushing prior to gold extraction and this consumed immense amounts
