Concentration of Ores
Explanation: In electromagnetic separation, the powdered ore is dropped over a conveyer belt moving around two rollers, one of which has an electromagnet in it. As the ore particles roll over the belt, the magnetic particles are attracted by the magnetic roller. As a result, two heaps are formed separately.
