The variable of froth velocity is an effective flotation optimal control parameter in the machine vision based flotation monitoring and control, which closely related to the flotation performance indices. However, the bubble velocity extracted based on digital image processing is often difficult to accurately extract, due to the inevitable rotation, scaling and the collapse of the bubbles deformation...
In a typical flotation cell circuit, the optimum cell performance depends largely on the ability of the operators to monitor and control the speed at which the froth crosses the lip of each cell. Hence, the froth flowrate is an essential tuning variable for flotation optimal monitoring and control system based on machine vision. However, the froth velocity is difficult to be measured accurately by...
