Tribo-electrostatic behaviour of high ash non-coking

Nov 01, 2006 However, these techniques are not economical for high ash non-coking coal in fine size fractions of − 500 μm. The dry beneficiation of coal is attractive due to easy handling of coal, lower energy cost, no dewatering and no drying of solids. Electrostatic separation for the beneficiation of coal is one such dry technique.
