What type of ores can be concentrated by magnetic separation method?

The process that is used for magnetic separation detaches non-magnetic material with those who are magnetic. The ore which are attracted by magnetic field can be concentrated by the process of magnetic separation. Iron and its compounds are attracted by the magnet, so ores of iron such as haematite (Fe2O3), magnetite (Fe3O4), siderite (FeCO3), and iron pyrites (FeS2) can be separated by the process of magnetic separation.


In this method, the finely grinded ore is made to fall on a rotating magnetic roller. The non-magnetic particles fall at a distant container due to gravity but the magnetic particles fall on the container just below the roller due to magnetic attractions.


In this way, the magnetic and the non-magnetic particles can be separated by this method.
