Usually we call the medium that greater than the density of water as heavy medium, so beneficiation in this medium called heavy medium beneficiation. In the medium, light mineral floats in the surface, heavy mineral subsidence, then heavy mineral (ore concentrate) and light mineral (gangue) can be collected separately, Heavy medium beneficiation can separate wide range of materials. This method the end step, first the ore should be crushed and grinded into fine particles, proceed a rough separation by the spiral chute, then collect the ore concentrate particles through the shaking table, and get the iron ore concentrate. It is widely applied to hematite (brown) iron ore, manganese ore, tungsten ore, tin, gold, precious metals such as tantalum and niobium ore mine.
