Moreover, the magnetic field density of magnetic separation is 95.5 kA/m and 159.2 kA/m, respectively. The concentrate of the magnetic separation is the final iron concentrate (titanium magnetite), and the tailings are used as the feed for the separation of ilmenite ores (FeTiO 3). The fineness of the regrinding is 80% passing 74 μm.
Low intensity magnetic separation pulls out metallic iron and magnetite. The concentrates pass through a high intensity magnetic separator to pull out the ilmenite fraction—46 to 48% TiO2. The non-magnetic fraction is subjected to high intensity electrostatic separation which removes the high grade rutile—94-95% TiO2.
