Magnetic separation of weakly magnetic copper minerals

Abstract: High Gradient Magnetic Separation of chalcopyrite and bornite, both weakly magnetic copper minerals with mass susceptibilities of about 0.1 × 10 -6 m 3 /kg and 0.2 × 10 -6 m 3 /kg respectively, has been performed. Initially pure mineral samples were processed before turning to copper samples with decreasing content of the minerals. These were: a concentrate, flotation tailings and
