Flotation cells and flotation machine made by Fote, the Chinese famous flotation-cell manufacturer, have the following advantages: high air absorption rate and low energy consumption. There are three functions of each tank: air suction, pulp suction and flotation separation. They form the flotation loop on their own without any accessory.

This has allowed a flotation cell to be modelled using the chemical reactor analogy; whereby the removal of solids from the pulp phase is defined by a first order rate equation. This means a bank of cells can be approximated by perfectly mixed CSTR's in series (Gaudin, 1957, Niemi and Paakkinen, 1969, Atkins et al., 1986, Yuan et al., 1996).

Mechanical flotation cells utilise an impellor to agitate the slurry and produce turbulent regions for bubble particle attachment, whereas in pneumatic flotation cells pulp and air are introduced together into the cell through a nozzle, also termed a downcomer, that promotes bubble-particle contact (Gupta and Yan, 2016).
