Concentration of Gold Ores - Artisanal Gold Council

Concentration of Gold Ores – a Key to Reducing Mercury Use in Artisanal and Small Scale Gold Mining. By Kevin Telmer - June 3, 2012.

Concentration means increasing the amount of gold in ore or sediment, by selectively removing lighter particles. If employed effectively, concentration methods can eliminate or greatly reduce the need for mercury. Before concentration can begin, ore must be crushed or milled to liberate gold particles from rock and to decrease grain size.
