  • Lotta Casey ORGANIC BINDERS FOR IRON ORE

    Iron ores generally contain vein minerals, such as silicates. For the steel industry the iron oxides must be concentrated, and in this process the ore is ground into fine particles [1]. The iron oxides are then reduced, at low temperatures by direct reduction [2, 3] or more commonly at high temperature in a
