  • Mineral Jig Separator Jig Concentrator Mineral Processing

    Introduction: A jig separator is a device 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. A typical jig consists of a waterfilled tank known as a jigcell, with a horizontal jig screen
