  • Difference Between Magnetite and Hematite | Definition

    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
