The process yields about 90% of pure gold. However, this percentage of gold is not acceptable in the industry, as it comes with other minerals, such as copper, silver, iron, or aluminum. Smelting comes as the most crucial step of the entire gold mining.
WebThe final stage of gold production -- refining -- involves removing impurities that remain after the smelting process. Refining companies receive doré bars, as well as scrap gold, and reliquefy the metal in a furnace. Workers add borax and soda ash to the molten metal, which separates the pure gold from other precious and less precious metals. WebApr 25, 2024 · Smelting is a process of extracting metals from their ores at high temperatures. Ores are mostly chemical compounds of metal with other elements, like oxygen sulfur. Smelting utilizes heat, and a reduction agent like coal, to extract the other elements from the metal according to Cornish Mining World Heritage.
