Vedclass · Answer

(A) The magnetic separation method is used for the concentration of ores where either the ore or the impurities (gangue) are magnetic in nature.Iron ores,such as magnetite $(Fe_3O_4)$ or hematite $(Fe_2O_3)$,are magnetic.In this process,the powdered ore is passed over a conveyor belt moving over magnetic rollers.The magnetic ore particles are attracted to the magnetic roller and fall closer to it,while the non-magnetic impurities fall further away,allowing for effective separation.Therefore,iron ore is concentrated using this method.

Which metal ore can be concentrated by the magnetic separation method?
