dc.description.abstractA multi variable control strategy for a grinding circuit at East Driefontein has been implemented by others and has enabled it to operate under stable conditions. The next development needed was to find conditions under which tne efficiency of the circuit was the greatest. Optimum set points exist for the multi variable controller to keep the circuit at its most efficient state. This project was done to determine these set points, and how it affected the operation of the circuit. The strategy involved the collection of process data, the development of mathematical models and the determination of these optimum set points by simulation, This option reduced interference with routine production operations, which is often a prohibiting factor during any development work on an existing process. The optimum set points were successfully determined, and were compared with previous findings and current plant practice.en_ZA
