Get PriceOct 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.
Get PriceMagnetic separation method is based on the difference of mineral magnetic, bearing different forces in the magnetic field of magnetic separator, resulting in material separation. It is mainly used for sorting ferrous metal ores (iron, manganese, chromium); as well as nonferrous and rare metals.
Get PriceFig. 5 shows the iron ore after the process of magnetic separation. The concentrate (b) has a pronounced dark color due to the iron oxides in its composition while the tailings (shown by clastic rocks) are lighter and partially transparent (a). Fig. 5. Iron ore after magnetic separation: (a) tailings; (b) ironore …
Get PriceDry Magnetic Separation of Iron Ore of the ... An implementation of twostep concentration (afterpurification) allowed increasing the iron content in the concentrate up to %. It forces to upgrade the process of dry magnetic separation or carry it out in the liquid phase (socalled, wet separation).
Get PriceThe ore which can be attracted by the magnetic field can be concentrated by the process of magnetic separation. Among the ores mentioned in table , 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.
