But there are still knowledge gaps in the fundamental understanding of these turbulence-controlled micro-processes in flotation machines. It can be seen from Fig. 1 that three distinct hydrodynamic zones exist in a conventional flotation cell. The bottom region that is closest to the impeller is a turbulent zone that has the strongest turbulence.
