Why haematite can be concentrated by magnetic separation

The Manufacture of Steel. On a world scale the most important ore is haematite (Fe2O3), but in New ... This technology is used because the titanium dioxide present in the ore ..... Initial separation is effected by magnetic separators which rely on the magnetic properties of magnetite and tintanomagnetite

    Jan 31, 2018 Hematite has unpaired electrons that cause its magnetic properties. It is paramagnetic because it has only ferric ion (Fe 3+).The electron configuration of Fe 3+ is 1s 2 2s 2 2p 6 3s 2 3p 6 3d 5 where 5 unpaired electrons are present. Therefore, hematite can be separated from a mixture using high-intensity magnetic separation methods which use magnetic fields with intensity ranging from 0.02-4
