Dense-Heavy Medium Separation HMS / DMS Process
Heavy (Dense) Medium Separation Liquids The low SG range of liquids are used for coal/ash samples, while most mineral samples are separated in the range 2.50 to 4.0. [Suspensions of ground material (known as media – usually magnetite, S.G. 5.1, and/or ferrosilicon, S.G. 6.8) are used on larger scale laboratory samples and in industrial ...

Dense medium separation | Machines | Ad Rem
However in the Ad Rem bi-directional design, the medium together with solids is injected over a large separation zone, making it almost impossible to bury floats with sinks. 2. The stability of the medium. A typical dense medium bath is relatively deep, and this makes it difficult for the suspension particles to remain in suspension.

Heavy media separation (DMS) Heavy media separation (DMS) is the most precise of all the industrially applied density separation processes but is probably also the most complicated. It is similar to heavy liquid separation in that results are not subject to operator discretion and are conducted at a defined density.

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.
