Magnetic Fractionation of Sphalerite in Zinc Concentrates
B. J. WALSH
Segregation of sphalerite .minerals in zinc concentrates into christoph1te, marmatite arid -ordinary sphalerite by means' of magnetic fractionation is investigated. A Frantz ferromagnetic filter, 1.2 amp., and a Dings magnet, 0.3 amp., is used to fractionate seven zinc concentrates produced in the Province of Quebec.
