concentration of gold in ore

Concentration of GoldOres – a Key to Reducing Mercury Use in Artisanal and Small ScaleGoldMining. Posted 3rd June 2012 by Kevin Telmer. In artisanalgoldmining, mercury is essentially used to concentrate thegold. It does this by bonding with thegoldto form a heavy amalgam that is then easily separated from the other minerals.
