The heavy-media separation process, or HMS, employing ferrous media, usually ferrosilicon and/or magnetite, is the most generally used process for sink-float separations. A stable medium over the range of specific gravities from 1.25 to 3.40 can be maintained within close limits and is cleaned and recovered by magnetic means.
Dense medium separation (DMS) is one of several preconcentration methods used for early waste rejection from of-mine ores at relatively coarse particle sizes prior to additional milling and run-beneficiation. DMS has been used extensively in the coal, diamond, mineral sands, base metalsand

Dense medium separation (DMS) is a robust process that can be conducted at particle sizes as coarse as 300 mm and as fine as 500 µm with high separation efficiency, depending on liberation characteristics of the value minerals. The DMS process involves three steps: feed preparation, dense medium separation, and ferrous-based media recovery.
Heavy Media Gravity Separation Heavy media gravity separation involves using a mixture of fine media material, such as magnetite (SG 5.1) or ferrosilicon (SG 6.8), suspended in a slurry of water, to produce a media slurry with a specific gravity that will allow low density material(s) to float, and other high density material(s) to sink.

Gravity separation is the separation of two or more minerals of different specific gravity by their relative movement in response to the force of gravity and one or more other forces (such as centrifugal forces, magnetic forces, buoyant forces), one of which is resistance to motion (drag force) by a viscous medium such as heavy media, water or ...
dense-medium separation (heavy-medium separation, HMS) The simplest of the gravity separation processes used to concentrate minerals before their final grinding and liberation.It is also used to separate coal from the heavier shale.Heavy media of suitable density are used, in which lighter minerals float and denser minerals sink.
The density of tin（Cassiterite） ore is larger than the paragenetic mineral, so the mining process of tin（Cassiterite） ore apply gravity separation. However, all kinds of Iron oxides exist in those ore, like magnetite, hematite, etc., which cannot be well separated by using gravity or flotation separation.
