Column flotation cells, like mechanical cells, are used to perform mineral separations. Column cells do not use mechanical agitation (impellers). Instead, mixing is achieved by the turbulence provided by the rising bubbles. Columns are mostly used to produce final grade concentrates because they are capable of high selectivity.

Flotation machines and flotation columns are widely used as separation equipment for coal sludge. In order to obtain better flotation results for different particle sizes, the bubble distribution and size in the flow field need to be studied. In this paper, a novel three-phase fluidized bed flotation column (TFC) was designed, and the shear effect of liquid velocity …

The value of J g is defined at the top of the column where d b can be expressed as d bO and carrying rate (C r) is the carrying capacity (C a) of the flotation column. The relationship between the bubble diameter d b and the superficial gas velocity J g in the collection zone of a flotation column can be approximately given as: (5) d b ∝J 0.25 g.
