Solution
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.
