Considering the different gold minerals present alone or combined with the host rock, it will be necessary to discharge the unwanted material in order to increase the concentration of gold in an economically manner.
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 ...
Methods of Gold Mining Geology In. Gold mining is the process of mining of gold or gold ores from the ground There are several techniques and processes by which gold may be extracted from the earth Placer mining Placer mining is the technique by which gold that has accumulated in a placer deposit is extracted.
