the control loop will attempt to add water to Cyclone 1 sump to achieve a particle size of 15%+ 300 µm. If the hardness of the ore increases, the particle size in the mill discharge from ball mill 1 will increase. With the same water addition to sump 1 the particle size of Cyclone 1 overflow will increase. This will decrease the ratio, and hence
