Separation Behaviour of Iron Ore Fines in Kelsey …
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

Enhanced gravity separation
The potential use of the Kelsey Centrifugal Jig to clean fine coal has been studied. It was found capable of cleaning coal at very fine sizes, at least to 0.038 mm at relative densities as low as 1.6. This effect was however very dependent upon the solids feed rate and the absence of significant amounts of clay slimes. comparisons with a spiral and a laboratory scale Jameson …
