Mineral Jig Separator | Jig Concentrator
Introduction: Jig concentrator (jig separator, 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. A typical jig consists of a water-filled tank known as a jig …
