Jig separator (jig concentrator, jig machine) is a equipment that drives pulses of water upwards through a thick bed of settled sediment to keep it loose and agitated.This achieves gravitational separation by allowing the denser minerals to sink easily and quickly through the lighter minerals. Jig separator are widely used in various heavy metal, metallic and …

Spiral concentrator is a gravity separation equipment, consisting of a spiral channel connected to a vertical support. Separation of particles in spirals is based on particle size and density and the combined effect of gravitational forces, centrifugal forces, drag, and Bagnold forces (forces related to Newtonian fluid) on the particles [1,2,3].As …
