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 …
The paper discusses various aspects of the application of heavy-medium separation to the processing of hematite ore at Sishen and Thabazimbi. The two main factors to be borne in mind in the design of a plant for such beneficiation are the Iow unit value of the iron ore produced and the high separation densities required.
