2021-9-25  As for regrinding, mineralogy on the rougher concentrate would have to be done to determine the liberation size (P80). Isamills are excellent for regrinding because they tend to produce less fines and a tighter size distribution. I recommend that concentrators determine the ball mill efficiency, cyclones efficiency and grinding circuit efficiency.
