Magnetic separation takes advantage of differences in the magnetic properties of minerals. Minerals fall into one of three magnetic properties: ferromagnetic, paramagnetic and diamagnetic. Ferromagnetic minerals are themselves magnetic (, magnetite and pyrrhotite) and can be easily separated from other minerals with a magnet since they will ...

Abstract: Magnetic nanoparticles (NP) of magnetite (Fe3O4) coated with oleic acid (OA) and dodecanoic acid (DA) were synthesized and investigated through Transmission Electron Microscopy (TEM),magnetization M, and ac magnetic susceptibility measurements. The OA coated samples were produced with different magnetic concentrations (78, 76, and 65%) and the DA sample with 63% of .

Further tests showed that commercial heavymedia magnetite has up to a 20 percent lower magnetization than bulk magnetite. Commercial magnetite often contains significant amounts of α and γFe2O3, in addition to magnetite. As αFe2O3 is nonmagnetic, it is not removed in the magnetic separator and is discharged in the refuse.
