    Magnetic separation based on differences in magnetic properties of the ore components. If either the ore or the gangue is attracted towards the magnetic field, then the separation is carried out by this method. For example, iron ores are attracted towards the magnet, hence, non–magnetic impurities can be separated from them using magnetic separation.Here, Haematite, Magnetite, and Sidderite ...
