ABSTRACT Inherent limitation of the mechanical flotation cell is the entrainment of hydrophilic particles (gangue) in the water reporting to the froth. In this study, a combine column and cell flotation process was proposed to reduce the entrainment of gangue particles and, ultimately, ash content of coal flotation concentrate in Datun coal …
