Jigging
The jigging action causes the lighter particles to be carried away by the crossflow supplemented by a large amount of water continuously supplied to the concentrate chamber. Jig efficiency improves with relatively coarse feed material having wide variation in specific gravity. Jigs are widely used as an efficient and economic coal-cleaning device.

AIR JIG. The Pneumatic process of beneficiation is the best suited option for Coals which has very high percentage of Near Gravity Material. This method involves size reduction and screening of coal to segregate it into defined sizes followed by concentration i.e. separation of particles into fractions more homogeneous in nature.
