the extraction or mining process of gold ore

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
