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. It means that electrochemical interactions between the grinding media and Chalcopyrite let to decrease in floatability of material.
