Q. Explain about Magnetic Separation ?
This process is based on the difference in magnetic properties of minerals. If the ore but not the gangue is attracted by a magnetic field, it may be concentrated to-yield a sample which is rich in the metal. The pulverised mineral is passed over a rubber belt which goes on a pully in a magnetic field. The non-magnetic gangue particles fall off in a vertical position when the belt passes over the pully, but the magnetic ore clings to the belt. When the belt passes out of the influence of the magnetic field, the ore drops off. Magnetite (Fe3O4), haematite (Fe2O3), chromite (FeO.Cr2O3), wulfrarmite (FeWO4), and ilmenite (FeO.TiO2) are some of the minerals which are separated from non- magnetic impurities by this process.
