Grinding process optimization is an exciting new tool for maximizing the performance of existing mineral processing plants. This paper discusses the methodology of optimization which involves plant sampling, pilot tests, modeling, computer simulation and plant verification. The methodology developed emphasizes the interactions among operating variables and design options. Two example applications demonstrate that AG and SAG optimization provides the basis to increase grinding throughput up to 10 percent. This sys- tem optimization technology has been proven to be very cost effective for grinding plant performance improvement.
