Flotation of coarse coal particles in a fluidized bed: The ...

A limitation of conventional flotation cells is imposed by the mass of coal particles that can be carried on the surfaces of the bubbles in the froth, as determined by the so-called carrying capacity, tonnes/hr/m 2 of column area. Normally, excess coal will be rejected into the tailings, if the feed rate is too high.
