Dry Magnetic Separation of Rod-Mill Feed at Minntac ...

Abstract. Pilot-plant testing at the Coleraine Research Laboratory has indicated the potential benefits of dry magnetic separation (cobbing) of Minntac rod-mill feed. Therefore, a prototype commercial unit was installed on line 18 to establish the benefits of dry cobbing. Line 18 was operated with and without dry cobbing on alternate days.
