Gold extraction QueensMineDesignWiki

The efficiency and recovery of chemical processes involved in gold extraction is exclusive to the mineralogy of the ore. Gold may exist as free nuggets or particles in alluvial or elluvial deposits or as native metal in other minerals. The gold mineralogy of any given ore deposit is unique to all others due to variations in the following:

Gold Extraction / Mining Gold

Extraction of Gold using the Borax Process. The borax process is also an environmentallyfriendly method of extracting gold. Here the goldbearing rock material is placed in a melting crucible and then borax (sodium borate) is added. The borax sinks the melting point of the ore mixture and makes the molten mass more fluid.
