Electromagnetic separation. A process of removing magnetic materials from relatively nonmagnetic materials, using electromagnets which travel along a conveyor, over a drum, or into a revolving screen. So, from gangue and ore, one of them must be a magnetic material and other must be non-magnetic. Option D is correct.
