They mainly rely on increasing particle size by selective aggregation and decreasing the bubble size by using nano or microbubbles, but also on using reactor-separator type flotation cells which promote a much stronger particle–bubble interaction. The pros and cons of these strategies are discussed in this paper.

Flotation cells have a wide range of applications in the field of particle separation as a traditional flotation unit. Due to the declining ore grades and the increasing market demand for mineral resources, recovering particles in a wider range of sizes efficiently is a challenge that plants must face, but which is not an advantage of traditional units.

Mechanical flotation cells can be broken down into two broad categories based on how air is introduced to the cell. In a self aspirated flotation cell air is introduced to the slurry, the vacuum created by the rotorusing . In a forced air flotation cell air is generated external to the cell by a low pressure blower,, and pumped down the

In a conventional flotation process, the bubbles are usually generated by breaking external air using an impeller in a mechanical flotation cell or a bubble generator in a flotation column. Their sizes are generally in the range of a few hundred microns to a few millimeters (Vinnett et al., 2016). Hydrophobic particles are collected by bubbles ...

If the cell air flowrates are not controlled individually, and air is fed to a group of cells, butterfly valves are often operated manually to adjust the flow to each cell. Lastly, Laurila et al.
