In gravity separation, the shaking tables are the most widely used and very efficiency sorting equipment for fine ore separation. The shaking table beneficiation is not just applicatied as an independent beneficiation method, but it also often combined with other beneficiation methods such as jigging, flotation, magnetic separation by centrifugal concentrator, spiral classifier, spiral chute

Electrostatic separation enables the separation of a wide range of minerals and this example, separating Pyrite from Silica Sand, provides a good example of the separation process. A feed of conducting (Pyrite FeS 2 ) and non-conducting (Silica Sand SiO 2 ) powders is fed via a vibratory feeder onto an earthed, stainless-steel roll revolving at a pre-determined rate.

About 300 g/tonne of ore is required for efficient separation. The efficiency of the hydrophobic action increases, but the selectivity to ore type decreases with increasing length of the hydrocarbon chain in xanthates. The chain is shortest in sodium ethyl xanthate that makes it highly selective to copper, nickel, lead, gold and zinc ores.

Dry electrostatic separators can provide economical separation of even the smallest and finest residual copper particles from cable scrap. Wet separation methods, such as so-called “water tables,” require further processing of wet plastics, which may not be economical in light of the additional drying time required.
