Explain magnetic separation process of ores with the help of a neat, labelled diagram.
Magnetic separation process:
a. The magnetic separation process is based on the differences in magnetic properties of the ore components.
b. If either ore or the gangue is attracted by a magnet, then the ore can be separated from the impurities with the help of magnetic separation method.
c. It requires an electromagnetic separator which consists of a brass or leather belt moving over two rollers, one of which is magnetic in nature as shown in the figure.
d. Powdered ore is dropped over the moving belt at one end.
e. At the other end, the magnetic portion of the ore is attracted by the magnetic roller and falls nearer to the roller, while the non-magnetic impurities fall separately farther off.
