Mineral Jig Separator | Jig Concentrator
Jig separator (jig concentrator, jig machine, mineral jig, mining jig) is a mining gravity separation 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 gravity ...
