We observed that, particle size decreased significantly due to regrinding while floatability of the feed was more than discharge. Moreover, floatability of each fraction ( 400, +400325) in mill feed and discharge was studied. Results indicated that, the floatability of all fractions in the mill feed was more than the mill discharge.
