Magnetic separation method is used to separate the magnetic ingredients in the ores.
✓

Answer

  1. The magnetic separation process is based on the differences in magnetic properties of the ore components.
  2. When the powdered ore is dropped over the moving belt near nonmagnetic roller, the nonmagnetic particles are carried further along with belt and fall in the collector vessel placed away from 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.
    Thus, magnetic separation method is used to separate the magnetic ingredients in the ores.
