- Effects Of Jigs Mineral Processing To The Economy Of Kentucky In
minerals. INTRODUCTION With the worldwide emphasis on lower grade deposits the use of low cost pre-concentration will play a greater part in mineral processing technology. In order to achieve optimum metallurgical efficiency you must recover the valuable mineral at the coarsest size possible and reject tailings at the coarsest size possible.

Jigs are continuous pulsating gravity concentration devices. Jigging for concentrating minerals is based exclusively on the differences in density of the particles. The elementary jig (Fig. 13.29) is an open tank filled with water. A thick bed of coarse heavy particles (ragging) is placed on a perforated horizontal jig screen.

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 various heavy ...
