(Horst 1985, p. 3A-5). Average grinding sizes for the ore can be brought down to 10-15 microns at the very most, if using long grinding periods on a product which has already passed a -200 mesh sieve. Some specific mills are reported to be available, which are capable of grinding the ore down to sizes of 5 microns or less.
