Methods of Gold Mining - Geology In

Placer mining is the technique by which gold that has accumulated in a placer deposit is extracted. Placer deposits are composed of relatively loose material that makes tunneling difficult, and so most means of extracting it involve the use of water or dredging. Panning Gold panning is mostly a manual technique of separating gold from other materials.

Finding Better Ways to Mine for Gold General

In gold mining, cyanide solution is sprayed over vast heaps of crushed ore that is spread atop giant collection pads. The cyanide dissolves the gold from the ore as the solution trickles through the heap. The pad collects the now metal-impregnated solution which is stripped of gold and resprayed on the stacks until the ore is depleted.

Concentration of Gold Ores - a Key to Reducing

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.
