has successfully increased the tonnage and recovery of copper through the implementation of the Stack Sizer ® in the grinding circuit. Through this implementation, has helped copper miners improve copper recovery and reduce grinding circuit costs, which ultimately leads to increased profits for the concentrator operation.
One of Palabora Mining Company''s operations had six parallel milling circuits consisting each of a rod mill followed by a ball mill in open circuit (du Plessis, 2001). It reported % gain in recovery, as well as a throughput gain, using an inhouse MPC designed to either reduce particle size for a given throughput, or increase throughput ...
