Dense Media Separation is a well-known sink-float method and technology used within the coal, iron ore and diamond industries. In the process of Dense Media Separation in diamonds, a powdered ferrosilicon (which is an alloy of iron) is suspended in water to form a very defined pulp density (heavy liquid), close to the density of diamond (3.52 g

The DMS process involves the mixing of a pre-prepared ore stream with a dense medium of selected specific gravity (SG) in a mixing box and passing this mixture through a dense medium cyclone (DM cyclone). It is here that separation of the high and low SG fractions of the ore occurs

The Dense Medium (Liquids) Heavy liquids are widely use in laboratory for appraisal of gravity-separation techniques on ores. Heavy liquid testing performed to determine, -Feasibility of dense medium separation on a particular ore. -Economic separating density, or to assess the efficiency of an existing dense medium circuit

Dense Medium Separation (DMS) uses the characteristic differences in density of the input material to enact a gravimetric-based separation. Due to the robustness of the process, DMS can be used in the separation of minerals, ore bodies and scrap metals. Dense Medium Separation is also capable of handling a wide range of feed densities, starting

Sep 01, 2010 Typically, run-of-mine iron ore is crushed to be −100 mm for liberation of Fe-rich component such as hematite. The ore particles of +6 − 100 mm in size are treated by the wet dense medium separation , for which the density of the dense liquid is adjusted at 2750–3150 kg/m 3. Although development of dry separations for iron ore is strongly needed, the dry dense medium separation has
