gravity separation for coal 38883

Gravity separation of coal and mineral matter was examined in this study using closely spaced inclined channels to promote a new and powerful density based separation mechanism. For relatively fine feed, less than 0.50 mm, it was possible to achieve strong rejection of mineral matter down to a particle size of 0.038 mm. Gravity separation of .
