Jul 10, 2020· The larger particles flow to feed the ball mills while the fine particles report to two flash flotation cells. 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 ...
