seven trustr-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
an implementation of two-step concentration afterpurification allowed increasing the iron content in the concentrate up to 48.2%. it forces to upgrade the process of dry magnetic separation or carry it out in the liquid phase so-called, wet separation . fig. 5 shows the iron ore after the process of magnetic separation.
this chapter introduces the principle of how low-grade iron ores are upgraded to high-quality iron ore concentrates by magnetic separation. magnetite is the most magnetic of all the naturally occurring minerals on earth, so low-intensity magnetic separators are used to upgrade magnetite ores.

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
maximizing the recovery of fine iron ore using magnetic separation by m. dworzanowski* synopsis the beneficiation of fine iron ore will increase in importance in the future because most new iron ore resources will be in the form of lower grade ore deposits that will require liberation of iron ore minerals at finer sizes.

probably the biggest financial failure of edison's career was the magnetic ore-separator. the idea, which edison's laboratory experimented with during the 1880s and 1890s, was to use magnets to separate iron ore from unusable lower-grade ores. this would mean that abandoned mines could be profitable
our ferromagnetic wet drum separators can be used in iron ore separation plants in both rougher or cleaner beneficiation applications. we also provide demagnetising solutions that reverse the residual effects that magnetic separation has on the magnetic viscosity of ferrous slurries, to return the mineral stream to an acceptable viscosity for
