Magnetic separation takes advantage of the fact that magnetite is strongly magnetic (ferromagnetic), hematite is weakly magnetic (paramagnetic), and most gangue minerals are not magnetic (diamagnetic). A simple magnetic separation circuit can be seen in Figure 1.2.5 .A slurry passes by a magnetized drum; the magnetic material sticks to the drum, while the nonmagnetic slurry keeps flowing.
Luzheng Chen, Dahe Xiong, in Progress in Filtration and Separation, 2015. 2.1.4 Screen Magnetic Separator. Screen magnetic separator presents another magnetic technique for the cleaning of strongly magnetic minerals such as magnetite, based on the principle of magnetic agglomeration (Li, 2005).
2016-12-4 · pct Fe and only 2 to 3 pct SiO, when dry magnetic separation procedures are used. One of Edison''s pilot plants consistently produced concentrates of more than 71 pct Fe. Edison devoted eight years, at a cost of more than $2 million, to inventing a magnetic process and con- structing a plant for concentrating low grade iron
2018-11-15 · MAGNETIC SEPARATION Based on magnetic behavior matrial can be classified as" 1. Ferromagnetic –very strong magnetic susceptibility- iron, nickel and cobalt. 2. Paramagnetic –weak magnetic susceptibility – a) Weakly magnetic b) Strongly magnetic 3. Diamagnetic particles –repelled by magnet 4. Non magnetic
Iron Ore Magnetic Separation Processing Plant Design Iron Ore Magnetic Separation Process Overview As we know iron ore is the important raw material for iron and steel making There are various kinds of iron ore in the nature but only several types can be used for iron and steel production like magnetite hematite and siderite and so on .
2015-9-28 · Magnetic substances Separation in ﬂ uid (wet) High magnetic force separator (dry) Aluminum separator Used for a coolant separator (removal of iron particles in grinding ﬂ uid, waste oil, cooling oil), drum separator (collection of iron ores, iron sand materials) and MAGFIN (removal of iron particles deposited in oil tanks). Magnetic drum
2009-8-26 · A DISCUSSION OF MAGNETIC SEPARATION TECHNIQUES 197 Introduction Minerals separation based on magnetic susceptibility differences in particles is accomplished wet or dry, at various intensities and in different basic machine configurations. The following types of industrial magnetic separators can be found in a modern mineral sands plant:
2015-1-1 · Magnetic separation between iron and ceramic balls., Iron ball,, ceramic ball, S, south pole of magnet, N, north pole of magnet, f m, magnetic force, G, gravity, H, magnetic field intensity. Most mineral separating processes are carried out in water or a slurry, so fluid drag forces and surface interfacial tension are also competing forces.
Magnetic filtration has been applied in place of lime treatment by Feng and coworkers (2000).Ultrafine magnetic particles are used as magnetic seeds. At a dosage of 0.5 g/L magnetite, all fine precipitate flocs can be rendered strongly magnetic. The mine water is treated with hydrogen peroxide (to oxidize ferrous iron and manganese), followed by the addition of lime and magnetite to raise the ...
