उत्तर
The method shown in the figure is the magnetic separation method.
- The magnetic separation process is based on the differences in magnetic properties of the ore components.
- This method requires an electromagnetic machine which consists of a nonmagnetic conveyor belt moving over two rollers, one of which is magnetic in nature while the other is nonmagnetic.
- The powdered ore is dropped over the moving belt near the nonmagnetic roller. Two collector vessels are placed below the magnetic roller.
- The nonmagnetic particles are carried further along with the belt and fall in the collector's vessel placed away from the magnetic roller. At the same time, the magnetic portion of the ore is attracted by the magnetic roller and falls in the collector vessel near the magnetic roller.
