Heavy Media Separation Process

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.

Leeuwpan fine coal dense medium plant J r n a - SciELO

Leeuwpan fine coal dense medium plant mixed with magnetite in the launder and enters a second stage washing cyclone. The product of the secondary cyclone is sent to a product magnetic separator and the discard of the primary cyclone is routed to the discard magnetic separator. The discard of the secondary washing stage is recycled back to the feed.


The medium is not homogenous with respect to fine size coal 2. The forces operating on fine particles inside the cyclone are too weak with respect to fluid resistance These problems can be eliminated by the use of heavy organic liquids or micronized magnetite In South Africa and USA, recent dense medium cyclones are used without desliming.

Integrated Heavy Media Cyclone & Flotation System

Heavy medium cyclones make use of a medium which is a homogenous mixture of water and dispersed magnetite. Density of the medium is regulated by adjusting the amount of magnetite in the mixture. Coal is mixed with the medium in a sump and fed to the HMC where the heavier ash material is separated from lighter coal due to density differences.
