Magnetic separator


Ans.
1.     A magnetic separator consists of a leather belt that moves over two rollers.
2.     Out of two rollers, one roller is an electromagnet.



3.     The crushed ore is allowed to fall on the moving belt of a magnetic separator, the magnetic portion in the ore is attracted by the magnet and forms a heap neat the roller.
4.     The nonmagnetic impurities (gangue) fall away and form a separate heap.
5.     Thus, magnetic ores are separated from nonmagnetic gangue and become concentrated.
