The flotation machine, also known as a flotation cell or flotation separator, is a device used in mineral processing to separate valuable minerals from gangue (unwanted material) based on their differences in hydrophobicity (ability to repel water) and buoyancy. Flotation machines are widely used in the mining industry for ore beneficiation and ...
5 It can be seen from Fig. 1 that three distinct hydrodynamic zones exist in a conventional flotation cell. The bottom region that is closest to the impeller is a turbulent zone that
Regardless of which type of flotation cell is used to achieve mineral or coal flotation, a machine has two main requirements: 1. ... The creation of a rising current of air bubbles is accomplished by a flotation machine (cell), which produces bubbles by mechanical agitation of the ore pulp, the direct introduction of air under pressure, or both ...

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.
