Gold Refinery
The dried gold sand is melted in a furnace and cast into bars. Depending on the capacity of the Gold Refinery installation, casting of 400 troy ounces (~12 kg) fine gold bars is done either manually by using a removable crucible and a casting table or by using a Gold Bar Casting Wheel. The gold bars are then cooled in a water bath.
Introduction of Mercury-Free Gold Extraction to Small-Scale Miners …
The mercury-free gold extraction method uses borax in the process of gold smelting. Borax is used in the smelting process because it lowers the melting point of gold and other metals. In this method, the mining of gold-bearing ore, the grinding of the mined material and the concentrating from sluicing are the same as in the amalgamation method.
