Magnetic separation is most used to separate natural magnetic iron ore magnetite from a variety of less magnetic or nonmagnetic material 7 Magnetizing reduction is one of the most effective unit operations in the treatment of low grade iron ores specially those which are poorly responsive to conventional beneficiation techniques such as froth flotation gravity separation and magnetic
Extensive investigations have been carried out on three iron ore slimes generated at Barsua Bolani and Meghahatuburu iron ore mines of India The studies include physical chemical mineralogical characterisation and beneficiation studies adopting conventional hydroclyclone and wet high intensity magnetic separator The characterisation
By magnetic separation two products of iron ore and barite concentrates were obtained by using a high intensity magnetic separator The fine fraction mm is about 20 by weight assaying Fe and BaO which needs further cleaning to reduce the barite content to meet the smelter specifications 52 Fe and 2 BaO The size mm fraction after concentration by H

The iron precipitates on the surface of the goethite to form large magnetic particles with a core shell structure and the precipitates are efficiently settled and separated by magnetic separation The results show that the iron content in the dry iron residue is more than 52 and the Ni content is less than which can be used in industrial applications to deal with a large amount of iron
Three disc Electromagnetic Separator is a Dry Intensified Magnetic Separator/High Intensity Magnetic Separator applicable for separations of tin tungsten tantalum niobium ilmenite rare earth ore chromite ores limonite columbium zircon rutile monazite andalusite garnet kyanite feldspar quartz and other minerals with magnetic differences or removal of iron in nonmetallic minerals.
Lower grade sources of iron ore generally require beneficiation using techniques like crushing milling gravity or heavy media separation screening and silica froth flotation to improve the concentration of the ore and remove impurities The results high quality fine ore powders are known as fines Magnetite Magnetite is magnetic and hence easily separated from the gangue minerals and
