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.
Hydrodynamics of froth flotation and its effects on fine and …
Variables of hydrodynamics are equally important as those of surface chemistry in determining the efficiency of froth flotation processes. In a mechanical flotation cell, macro hydrodynamics is responsible for solids suspension and aggregates transport, and micro-turbulence plays an important role in the sub-processes of …
The future of flotation
Unfortunately, the conventional flotation cell achieves high recovery only in limited size ranges. For example, a sulfide ore might float very well at 90 to 120 microns, but not at 50 or 150 microns.

Effect of ultrasound on separation selectivity and efficiency of flotation
The effect of the use of ultrasound in the froth phase on the flotation performance has been investigated in relation to the flotation rate of a complex sulphide ore. A series of kinetic flotation tests with and without ultrasound were conducted in a flotation machine with a 2-L cell, in which an ultrasonic probe is located in the froth zone.
