The Gold Mining Process. In addition to cyanide processing, gold ore is also processed with gravity separation. Advanced technology has enabled the amount of gold mined and processed to steadily increase over the years. For example, the worldwide production of gold in 2006 was 2360 metric tons. As of 2013, that number had climbed to 2770 metric ...
Completing OffSite Refining; Once the initial processing is done onsite, the gold is transported to an offsite refinery to undergo further refining. The purpose of this refining is to remove any remaining impurities. The crude gold is melted and then treated with chloride.
The final stage of gold production refining involves removing impurities that remain after the smelting 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. A sample is then taken to a lab for tests, or ...
