Why haematite can be concentrated by magnetic separation

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

    If the ore or the gangue can be attracted by the magnetic field, then the ore can be concentrated by the process of magnetic separation. Among the ores mentioned in table 6.1, the ores of iron such as haematite (Fe 2 O 3), magnetite (Fe 3 O 4), siderite (FeCO 3), and iron pyrites (FeS 2) can be separated by the process of magnetic separation

    Gravity separation process is used for the concentration of

    haematite. Gravity separation process is used for the concentration of haematite. Gravity method is based on the difference between the densities of the ore particle and gangue. It is used for the concentration of denser ores from the water soluble and lighter impurities (gangue). Oxide ores and carbonate ores are concentrated by this method
