Behaviour of bubble clusters in a turbulent flotation cell
Froth flotation is one of the most important methods for separation of ore in mineral industry. The method relies on the differences in chemical and physical properties of the valuable minerals and unwanted gangue minerals. The target mineral is treated with a reagent that renders the surface of particles hydrophobic.
Modelling of froth transportation in industrial flotation cells

Mixing and gas dispersion in mineral flotation cells
Abstract. Mineral flotation in mechanically agitated vessels (cells) involves complex interaction between bubbles, particles and the liquid phase. Ideally, just enough power input from the impeller is needed to so that the frequency of particle–bubble collision and attachment is maximised, while at the same time detachment events are minimised.
Mining
The tanks, known as flotation cells, are agitated; this adds air, forming bubbles to which the hydrophobic minerals link. As a result, the minerals rise to the top of the cell. There, they collect in a launder. The ore that does not float is taken away as tailings, which may be subjected to further flotation.

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.
