Flotation Control & optimisation

The main difficulty in controlling flotation levels is that they form part of a highly interconnected system. The control actions of one bank will therefore influence other banks and, unless handled correctly, disturbances will propagate through the circuit. This means that good level stabilisation control cannot be achieved by using controllers that only act locally. The top two figures on

Level control of flotation cells is a very complex task due to high interactions between the process variables. A control action implemented at any point in the flotation circuit tends to be transmitted to both upstream and downstream units, and sometimes with amplification. Large variations in the flow rate to the first cell and varying composition of the raw ore also cause problems. Fig. 1
