The screening process. The smaller ore will go on to the ball grinding mills where they will be further ground down. The larger ore will be routed to a pebble crusher to reduce the size to cm (½ in) and will return to the SAG mill stage. The ball mill product is pumped to cyclones which separate out the coarse material with the fine ore.
