Industrially, the most common dense media is a suspension of fine magnetite and/or ferrosilicon particles. An aqueous solution as a dense medium is used in coal processing in the form of a belknap wash and suspensions in air are used in waterdeficient areas, like areas of China, where sand is used to separate coal from the gangue minerals.

As such, three pneumatic processes were tested including Ore Sorting for the plus 10 mm material, Air Table Separation for 10 x 1 mm fraction and Triboelectric Separator for 1 mm fraction. The Dense Medium Cyclone is known to be one of the most efficient separation processes and thus was evaluated for the cleaning of 10 x 1 mm coal.

Fine coal processing with dense medium cyclones CSIR

Beneficiation of fine coal, nominally below mm, with densemedium cyclones was implemented as long ago as 1957 and cyclones are still being used to process fine coal today but the history shows that the application of cyclones in fine coal processing has not been nearly as successful as in the processing of coarser coal.

Large diameter cyclones (30", 33, and larger) are also available, with capacities approaching vessels also. Today dense medium cyclones are the most common coal cleaning device. For hard to clean coal (+10% near gravity material) in the size range of 50mm to mm (28 mesh), the dense medium cyclone is widely used.
