bed. The water movement is generated by the disc-valve controlled jigging air which acts on the water perpendicular to the direction of ore transportation from below the jigging bed. There are some considerable advantages of BATAC Jig over other beneficiation processes such as: 1. It is a water-only process so operating cost is relatively low. 2.
Upgrading of iron ore by jigging has been an emerging trend. Typically −10.0 + 0.15 mm material is considered for jigging where the problem of separation of finer particles is inherent.
The ore particles with small specific gravity are located in the upper layer, and the ore particles with large specific gravity are located in the lower layer. The medium used for jigging is water or air. The use of water as a jigging medium is called hydraulic jigging; the use of air as a jigging medium is called wind jigging.
