The present invention relates to a non-magnetic-force sorting apparatus. In other words, sand is mixed with light sand of silica and heavy minerals such as magnetite and monazite. Among useful minerals, magnetic and nonmagnetic materials are mixed. In the present invention, it is possible to carry out both the specific gravity sorting and the magnetic force sorting. Using the difference in specific gravity, first the heavy and light minerals are separated, and finally the magnetic and non-magnetic minerals in the heavy mineral are separated. By this device, it is possible to perform gravity screening and magnetic force screening at the same time. |
