Kelsey Centrifugal Jig (KCJ) works on the separation principles of a conventional jig employing a centrifugal force field. A much higher G-force (80 - 100 G) is ob-tained enabling the treatment of particles between 5 and 500 μm. The major advantage of enhanced gravity separation is its ability to reject composite particles more efficiently
