Dense Heavy Medium Separation HMS / DMS Process

23/06/2015· 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. It 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. In principle, it is the simplest of

Mineral processing

Dense medium separation can be performed using a variety of mediums. These include, organic liquids, aqueous solutions or suspensions of very fine particles in water or air. The organic liquids are typically not used due to their toxicity, difficulties in handling and relative cost. Industrially, the most common dense media is a suspension of fine magnetite and/or ferrosilicon particles. An

Dense media separation utilises a medium with a density in between the density of the ore and the gangue (commercially worthless) particles. When introduced to this medium, particles either float or sink, depending on their density, as relative to the medium.
