Jigging - Mineral Processing - Beyond Discovery
Batac jig is reported to treat both coarse- and fine-size coals satisfactorily (Chen, 1980) and has become an industry standard for coal cleaning (Zimmerman). Jig Feed In coal washing jigging is practiced on unsized material as coarse as 175 mm (7 in). In metal-milling practice jigging is now seldom employed on material coarser than 20 mm (e in).
Batac Jig for Cleaning Fine and Coarse Coal Sizes
The Batac jig can treat coarse as well as fine sizes of coal. In other words, it can handle any of the sizes now being washed in the various types of Baum jigs installed in this country. The standard Baum jig uses either plunger-type air valves or rotary valves. The Batac jig uses flat discs which are electronically and pneumatically controlled.

Jigging and its Applications - Gravity Separation
In the case of coal beneficiation, the top part of the bed is composed of the lighter, lower ash yield components of the coal, that is, the higher quality coal fraction. It is cut and separated from the bottom part which is composed of the denser, high mineral content components of the coal, that is, the lower quality coal fraction.
