· If the hardness of the ore increases the particle size inthe mill discharge from ball mill 1 will increase. With thesame water addition to sump 1 the particle size of Cyclone 1overflow will increase. This will decrease the ratio and hencethe control loop will add more water to keep the ratioconstant. However the amount of slurry reporting as freshfeed to the second milling circuit will increase.With the increase in feed material to the second millingcircuit and provided the circulating load stays constant theparticle size from Cyclone 2 will increase. The increase inCyclone 2 particle size will increase the ratio and hencewater addition to sump 1 will decrease to increase Cyclone 1particle size
