particle was discharged from the mill it saw the gravity concentration device. There were also some disadvantages: The gravity circuit had to process 3 or 4 times the new feed rate to the mill (the entire circulating load). Much of the feed material was fine and therefore thought to be unrecoverable by gravimmetric means.
