In thismethodof Magnetic Separation, we use the magnetic properties of certain metals to divide them from the non-magneticgangue. Here we place the powdered ore on a roller belt. One belt of this roller is a magnet. So the magnetic material attracts to the metal belt and stays on the belt. The non-magneticganguefalls in a heap from the belt.
