Constrained real-time optimization of a grinding

Because of the competition between the ground product fineness, which tends to improve concentrate grades, and the production capacity, which increases the quantity of sold metal, the optimization of a grinding circuit is usually formulated as one of these three objectives: maximize production at constant fineness maximize fineness at constant production optimize a weighted function of both above

2017-11-6  Maximization of CSE is the first of two optimization criteria for functional performance analysis. The second is maximization of the mill grinding efficiency, or, on a given ore, maximization of the grinding rate through the size of interest. Each of these is achieved by means of direct, planned, step-by-step manipulation of circuit
