The reference point is a conventional ball mill circuit in closed circuit with cyclones operating at 250% circulating load and having 38% of fine material reporting to cyclone underflow, resulting in a classification efficiency of 50%. This efficiency was chosen as an industrial practice "average" from the data presented in Fig. 6.
