Magnetic separation of iron

A magnetic separation device is being developed for removal of iron and heavy metals from water. The device consists of a column of supported magnetite surrounded by a movable permanent magnet. The mineral magnetite, or synthetically prepared iron ferrite (FeO x Fe2O3), is typically supported on var

    Jul 01, 2015 Efficient magnetic separation offseted the poor settleability and filterability of the precipitate. After magnetic separation of iron residue, the nickel solution was qualified and the dried iron residue contained more than 52% Fe and less than 0.6% Ni, indicating a promising alternative process for treatment of bulky residues of iron precipitate

    Feb 08, 2021 Secondly, the basis of magnetic separation is that pyrite is more magnetic than coal and/or can be partially converted into more magnetic compounds of iron upon treatment. Thus any separation or treatment can best be followed by magnetic susceptibility measurements which give a measure of force of separation

    Oct 06, 2021 Magnetic separation may be used for coal beneficiation when the gangue minerals contain such iron phases, however their very weak magnetic susceptibilities would require strong magnetic field strength (Dwari and Rao, 2009). Previous works on the magnetic separation of pyrite from coal have shown pyrite to be a weakly paramagnetic mineral
