Abstract
A control system for a froth flotation system receives inputs from one or more sensors comprising images of a fluid having bubbles and particles therein; some of the bubbles are attached to some of the particles and suspended in the fluid. For at least some of the bubbles with attached particles, it is determined from the inputs at least two contact angles at different locations at which the respective bubble is attached to the particle. These contact angles are used to predict a process improvement by which bubbles would more efficiently float the particles out of the fluid, as compared to that represented by the input images. An output is then provided for driving a graphical display screen, the output comprising at least one of: a) a graphical representation of the determined at least two contact angles; and b) a graphical representation of the predicted process improvement.
