  • Which Of The Following Ores Cannot Be Concentrated By

    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, nonmagnetic impurities can be separated from them using magnetic separation.zandrivierspoort magnetitehaematite ore by magnetic separation by muthaphuli synopsis kumba iron ores zandrivierspoort magnetite-haematite project aims to mine and beneficiate a magnetite resource with low contaminant levels to produce from mta to 2.5 mta product, which will be either a
