  • Dry Magnetic Separation of Bauxite Ore

    problems with bauxite ores are high iron and titanium contents. So, the removal of iron and titanium oxide is required in order to meet refractory specifiion. Use of gravity and magnetic separations in order to enrich A1203 content in bauxite has been reported in the past (Nandi 1996, Bhimarao 1997, Kasai 1993). Murray and Lannicelli (Loc.
