Dense medium separation (or heavy medium separation (HMS) or the sink-and-float process) is applied to the pre-concentration of minerals i.e. the rejection of gangue prior to grinding for final liberation is also used in coal preparation to produce a commercially graded end-product clean coal being separated from the heavier shale or high-ash coal.

Gravity separation is an industrial method of separating two components either a suspension or dry granular mixture where separating the components with gravity is sufficiently practical i.e. the components of the mixture have different specific weight. All of the gravitational methods are common in the sense that they all use gravity as the dominant force.

Liquid separation procedures can generally be assigned to one of two groups. (i) Gravity separation techniques use a gravity difference between particles within a residue. The procedure s success is considerably improved by using a liquid with a specific gravity (S.G.) value between the two main mineralogical components to be separated.

Laboratory heavy liquid separations result in two components the heavy fraction (or sinks) and the light fraction (or floats). In industry it is usually the heavy fraction of a mineral suite which contains the valuable component and which is separated from sand (silica) and other components having a density less than 2.7 g/mL.

39.3.3 Heavy media separation. Heavy media separation dates back to several centuries. Initially a fine magnetite was used as a heavy media. In 1936 a plant was designed employing organic liquid as a heavy media for treating anthracite coal containing ore. The heavy media process is usually used for treatment of coarse coal above 9.5 mm in size.
