Performance of a Dense-Medium Cyclone When Beneficiating Fine Coal

Abstract

The partition function has been determined for fine coal in a dense-medium cyclone. The partition curve is characterised by four parameters; the cut point, the separation efficiency, the short circuit to underflow and the short circuit to overflow. Each of these parameters is a strong function of particle size for fine coal. The effect of slimes in the feed is shown to have only a small effect on the measured partition curves
