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.

Characteristics of gravity concentration: (1) The processable materials have expanded from lump/coarse to fine/slime grained materials, and the lower limit of fed ore particle size during ore separation is 20 μm; (2) in addition to gravity, other forces are employed in order to intensify the gravity concentration process, e.g., the centrifugal …
For processing of fine particle ore and slime, the requirement is the opposite. (2) Fed ore volume and concentration. Fed ore volume will affect the flow velocity of the pulp on the table. As fed ore volume increases, the concentrate recovery rate decreases. As fed ore concentration increases, the stratification rate slows down.
