Modelling for froth flotation control: A review
Advanced flotation controllers based on froth image analysis have been developed in recent years. Machine vision can, for example, determine some characteristics of the froth surface at the top of a flotation cell, such as the number of bubbles, bubble size, bubble shape, density, speed and stability (Fu and Aldrich, 2019).

Probably the most significant area of change in mechanical flotation machine design has been the dramatic increase in machine size. This is typified by the data of Fig. 8, which shows the increase in machine (cell) volume size that has occurred with a commonly used cell manufactured by Wemco.The idea behind this approach is that as machine size …

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.
