Flotation control and supervision allow flotation circuits to maintain target concentrate grades and plant recoveries. The decision-making required for effective supervision of flotation control systems (e.g., selection of targets, setpoints, and setpoint limits) is enhanced by up-to-date information on total and component mass flows throughout the circuit.

The mass of the cleaner concentrate C c (n) at the nth cycle, which is normalized by the steady state value of the mass of the cleaner concentrate C c, is shown in Fig. 2 as a function of kT with the iteration number n as a parameter. C c is obtained by making the iteration number in Eq. (7) infinity large or solving the mass balance,, with CS c (n−1)=CS c (n).
