The control of flotation plants is by no means trivial. Flotation is one of the most interactive mineralsi?½ processing operations. The interactive nature of flotation circuits results in oscillations of levels and hence of grades and recoveries. Also, poor level setpoint tracking and disturbances have negative influences on grades and recoveries. The result is an unstable plant with limited ...
