Optimization of Comminution Circuit Throughput and

The goal of a comminution circuit is to grind particles to their liberation size, so that the valuable minerals are completely broken free from the gangue minerals. For the best grinding efficiency, all particles should ideally be ground only to the liberation size, and no finer. In order to accomplish this, the circuit should have the following
