A Pelletizing Cone for Dry Concentrates

THE Ontario Research Foundation has developed a family of dry magnetic concentrators which, when used in conjunction with a dry grinding mill such as an Aerofall mill, will allow the production of a completely dry magnetite concentrate. Previous experience with extrusion of iron ore and with pelletizing of fine iron concentrates suggested that it might be possible to develop a method particularly suited to the agglomeration of completely dry concentrates which might have some practical advantages over other methods of agglomeration.
