no flotation can occur. Contact between particles and bubbles can be accomplished in a flotation cell such as the one shown schematically in Figure 5. Figure 5: Simplified schematic of a conventional flotation cell. The rotor draws slurry through the stator and expels it to the sides, creating a suction that draws air down the shaft of the stator.

Flotation is about creating the proper energy dissipation rate in the cells to obtain optimal contact between the air bubbles and the particles for extracting the minerals. The function of the rotor/stator is to make bubbles from the induced air, suspend the particles, and create an environment for bubbles and particles to make contact and rise ...

Energy consumption is a key parameter in all of these approaches. Specific power, the power used per unit volume of a flotation cell (kW/m 3), is commonly used to define the energy consumption of mechanical flotation cells and has been used as a scale-up criteria (Harris, 1975). It has also been correlated with flotation kinetics (Schubert, 1989).
