Exploring the Efficiency of Magnetic Separation and Gravity
It was determined that most of the free utilizable components are present in the −100 + 0.0 µm class. Therefore, this class was further used in magnetic separation and gravity concentration tests, which are methods for successfully separating non-ferrous metal alloys and minerals into one product while separating tailings into another.

In this method of Magnetic Separation, we use the magnetic properties of certain metals to divide them from the non-magnetic gangue. 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-magnetic gangue falls in a heap from the belt.
