Artisanal and Small-Scale Gold Mining Without Mercury

Although many miners use mercury in artisanal and small-scale gold mining, it is possible to safely and economically recover gold without it. Mercury-free techniques are safer for miners, their families and local communities. They may also help miners market their gold at higher prices.

Concentration of Gold Ores Artisanal Gold Council

In artisanal gold mining, mercury is essentially used to concentrate the gold. It does this by bonding with the gold to form a heavy amalgam that is then easily separated from the other minerals. It follows therefore, that if mercury is used as a mechanism of concentration, producing concentrates of gold ores through other means can enable reduction or even elimination of mercury use.
