A Correlation Between Visiofroth Measurements and the

Minerals Cisa have developed Visiofroth a system which calculates parameters of the froth surface using vision from remote cameras mounted about individual flotation cells. The parameters calculated from this system can be utilised within process control strategies to achieve stabilisation or optimisation of the flotation process.
