The Kraut Machine is not used as widely as the two just mentioned. Its particular advantage is the intensity of the agitation produced between the rotor and the stationary cylinder, which is probably greater than that obtainable in any other flotation machine. On this account it is especially suitable for the flotation of gold ores.

The larger conventional flotation cells are also more energy efficient in that the total energy per unit volume is reduced. However, this is contrary to previous work which has shown that high specific energy input is required to improve the flotation kinetics of fine and/or slow floating particles (Mankosa et al, 2016).For example, conventional mechanical flotation …
