Column Flotation Cells
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.

Regulation of bubble size in flotation: A review
The bubbles are dissolved in the slurry to form a -slurry flow into the flotation column, and the bubbles are separated out with the decreasing pressure. Numerous studies have reported that the bubble generator of the flotation column produces bubbles of 0.2–0.8 mm in size [46, 47]. For bubbles generated using this bubble generator ...

Study of a Novel Fluidized Bed Flotation Column with …
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 …

Column flotation produces very well-defined, deep and stable froth layers that are washed with the application of percolating water from above, displacing gangue particles such as silicates and carbonates.
Development of a carrying-capacity model for column froth flotation
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.
