Arsenopyrite removal from pyrite concentrate using

Sep 01, 2018· The effect of grinding fineness is due to the fact that the liberation degree of pyrite minerals increases with further grinding; however, this reduces the recovery for the minerals. Considering the fineness of pyrite concentrate has reached 62.63% below 0.045 mm and further grinding would increase the operational cost, thus the further grinding to the pyrite concentrate was not adopted.
