Flotation is a very efficient unit operation employed worldwide to separate valuable minerals from gangue materials (this is called froth flotation) and in the treatment of wastewaters as a solid (liquid) water separation, removing several pollutants. This issue covers the advances in these two areas. Froth flotation is the most efficient and ...

NovaCell™ flotation machine can work up to 2 mm for sulphide minerals like chalcopyrite and galena, and 4–5 mm for coal particles, according to Jameson and Emer (2019). Despite the challenge of bubble-particle cluster formation beneath the froth phase, NovaCell™'s ability to recover coarse particles is significant.

Flotation stands out as a successful and extensively employed method for separating valuable mineral particles from waste rock. The efficiency of this process is subjected to the distinct physicochemical attributes exhibited by various minerals.

The other type of flotation cells is a column cell. Column cells are tall round tanks that use compressed air to create air bubbles via spargers or cavitation tubes. These cells are used to perform mineral separations. Column cells do not use mechanical agitation (impellers). Mixing is achieved by the turbulence provided by the rising bubbles.
