Beneficiation of fine coal of size 300 × 150 μm was investigated in a laboratory Kelsey jig. A number of process variables were studied while others were kept constant. Silica sand of size − 1.68 + 0.85 mm was used as ragging material to prevent pegging of the internal screen. The thickness of the ragging bed was established to be …

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

Kelsey reported that to reduce the Al 2O3 content to acceptable levels in the zircon product from kyanite-containing minerals, a Kelsey jig will probably be required, as the spirals alone will be unable to make a satisfactory separation between the two minerals [7].
