Mixing and Hydrodynamics in Flotation Cells | SpringerLink
The flotation process is a complex interaction between the physicochemical characte- ristics of the species involved and the hydrodynamic and operating conditions in flotation cells. Efficient cell design requires knowledge about the power to be provided and the time to be spent in the cell by each one of the phases.

What Are Column Flotation Cells?
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.

Coarseness of Particles in Flotation in Impeller-Type Cells
Abstract The study focuses on stability of particle–bubble attachment versus the size of particles attached to bubbles, design of a flotation cell and the input energy. The main force to tear away a particle from a bubble is assumed to be the inertia force conditioned by undulation of the gas–liquid interface. It is examined how the bubble …
