The ball mills are in "closed circuit", meaning that the discharge is pumped to the classifying units (primary hydrocyclones) and the particles will not pass to the next grinding stage until they are fine enough to feed through the flash flotation cells. The underflow from the flash flotation cells is pumped to the secondary hydrocyclones ...
