There are numerous methods of concentration and the methods are chosen based on the properties of the ore. Hydraulic Washing: This method concentrates the ore by passing it through an upward stream of water whereby all the lighter particles of gangue are separated from the heavier metal ore. This is a type of gravity separation. Magnetic ...


Nov 29, 2020· 1.Magnetic Separation: This involves the use of magnetic properties of either the ore or the gangue to separate them. The ore is first ground to fine pieces and then passed on a conveyor belt passing over a magnetic roller. The magnetic ore remains on the belt and the gangue falls off the belt. 2.Leaching: Leaching is used when the ore is ...
