Jan 31 2018 hematite has unpaired electrons that cause its magnetic properties it is paramagnetic because it has only ferric ion fe 3the electron configuration of fe 3 is 1s 2 2s 2 2p 6 3s 2 3p 6 3d 5 where 5 unpaired electrons are present therefore hematite can be separated from a mixture using highintensity magnetic separation methods which use magnetic fields with intensity ranging from 0024

3 gems with a high refractive index some gems cant be separated by refractive index because readings are otl over the limit of the refractometer fluid ri 181 however we can sometimes rely on differences in magnetic response to separate one type of otl gem from another for example natural red zircon may look very much like red spessartine garnet and demantoid garnet may look

Oct 04 2018 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 processing

A separation between magnets affects the force each exerts on the other isnt simply due to the fact that in the use of the magnetic pole model poles always come in pairs it would be much simpler if it would be possible to have a single magnetic pole on one magnet interacting with a single pole on the other but this doesnt happen
