Jigs and Fixtures: Types, Parts, Definition, Applications
A fixture holds and positions the work but does not guide the tool. Whereas a jig holds, locates and as well as guides the tool. The fixtures are heavier in construction and are bolted rigidly on the machine table. Whereas the jigs are made lighter for quicker handling, and clamping with the table is often unnecessary.

Jigging is one of the oldest processes used for concentrating heavy mineral particles from the light.
Jigs & Coal Preparation
Traditionally in coal processing jigs have been used to clean the coarse coal fraction, the +3/8″ or +¼" material. Today with the advent of modern fine coal jigs in the United States, its place was moved from the coarse to the intermediate coal circuit, the 3/8″ x 100 mesh. Recent theoretical performance and economic evaluations indicate ...
