Oct 04, 2018· Magnetic Separation and Iron Ore Beneficiation. Magnetic separation is an old technique for the concentration of iron ores and for the removal of tramp iron. Since 1849, a number of patents on magnetic separation have been issued in USA, and texts of some of the patents before 1910 describe a variety of magnetic separators for mineral processing.

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 …

magnetic separation iron from hematite. Separation of gibbsite from iron oxides such as hematite and magnetite is known to be extremely difficult due to the similarities in their surface properties.
