Magnetic separation method for concentration of ore

Sep 26, 2020 Sep 01, 2021 Concentration of ore is the process used to extract useful minerals by separating the gangue particles. Concentration of ore can be done by 4 methods: Hydraulic Washing, Magnetic Separation, Froth Floatation, Leaching. Hydraulic washing depends upon the weights of the metal and gangue particles

    Feb 06, 2018 Magnetite (composition Fe3O4) has a specific gravity ranging from 5.0 to 5.1, and is sufficiently heavy to permit of its concentration from gangue by specific-gravity methods, which have had an extensive application. The object of the separation, however, is twofold: the concentration of the mineral in the raw ore to a product of sufficient

    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
