An empirical model of the Kelsey Centrifugal Jig is presented. The model describes the partition of feed material to the jig concentrate, taking account of the main jig operating parameters: g-force, ragging characteristics and stroke length and of the material properties of the feed. The model has been tested against the laboratory-scale jig separation of tungsten slime tailings. The effect ...

Kelsey Centrifugal Jig is an enhanced gravity separator which allows separation of mineral particles in the fine size ranges. The Kelsey Jig is based on the principles of conventional mineral jig but operates at g –force 100 times that of gravity. This results in improved sepparation efficiency particularly in fine sizes.

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
