DenseHeavy Medium Separation HMS / DMS Process

HMS and DMS are acronyms for Heavy (Dense) Medium Separation and is applied to the process of preconcentration of minerals – mainly the production of a high weight, low assay product, which may be rejected as waste. In principle it is the simplest of all gravity processes and is a standard laboratory method for separating minerals of different specific gravity.

Heavy media separation (HMS) method has been demonstrated to be effective for separating highquality RCA from mixed CDW by means of sinkfloat separation in a heavy liquid. The heavy liquid recommended in ASTM C123 [19] includes zinc chloride (ZnCl 2) in water, 1,1,1,2tetrabromoethane (C 2 H 2 Br 4), and zinc bromide (ZnBr 2) in water.

While Figure 4 depicts a common singlepass flowsheet, each material of interest can be processed using customized sequence of separation stages (, reprocessing of the float / sinks streams at different densities and with or without intermediate size reduction stages).


Initial Laboratory analysis involved standardized heavy media separation using tetrabromoethane (TBE) to obtain separation of the total heavy mineral component (THM). Heavy media (TBE) separation funnels. Total heavy mineral contents of the whole sample were then calculated using the size fraction data. The THM sinks recovered from each ...

Gravity separation Wikipedia

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: 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.
