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.
