Introduction. The dense medium separation process (DMS) is a mature technology, and is widely used in mineral and coal processing. The dense medium cyclone (DMC) is the most ubiquitous of the DMS vessels in use, and deservedly so. It is efficient (when run properly), can process both coarse and fine sizes, and has a relatively small Images showing the laboratory and test rig used to track particles inside a dense medium cyclone and illustrating the orientation of the cyclone within the detector. Three variations of dense medium were prepared, composed of mixtures of magnetite (Fe 3 O 4,−45 μm,and specific gravity of 4.8 g/cm 3 ) in water to achieve feed densities of Features of near gravitational material tracers in a dense medium

It is a physically related phenomenon of size-by-size cyclone partition curves (Scott, Davis, and Manlapig, 1986;Napier-Munn, 1990, 2018 Dunglison, 1999). The dense media cyclone (DMC)Test work was performed using the cyclone rig as shown above. The rig includes a polyurethane VV-165-15 cyclone installed with a 35 mm spigot. A polyurethane cyclone was chosen as it contains no metal parts, which is preferred due to the application of a magnetic field to the system. The cyclone has a diameter of 165 mmDENSE MEDIUM SEPARATION USING A MAGNETIC CYCLONE

Heavy-Media-Cyclone Pressure Required to Maintain 9 Dc at Various Media Densities. Feed Pressure at 9 Operating Heads Table [image 145-3-9] For example, consider the typical particle size ranges reporting to the dense medium vessel (100 x 10 mm) and dense medium cyclones (10 x 1 mm). The arithmetic mean particle sizes are 55 mm and 5.5 As particle size decreases, the particles tend to spend a longer time in the main body of the cyclone due to higher drag force. With the particle density increasing to 1600 kg/m 3,which is the cut density ( Fig. 10 (c)), all particles go firstly with the downward flow to the conical part near the spigot, where the pressure gradient is quite high (see Computational investigation of the mechanisms of the “breakaway

Thus, initially, DM cyclones were at a maximum size of 710 mm inlet head and capacity of the order of 100 tph of raw coal feed, maximum lump size approx 50 60 mm.Title: A CYCLONE FOR A REASON Dense Medium Cyclone

Coarser coal was processed in dense medium vessels or jigs, and the fines were processed in spirals, water-only cyclones, or flotation.

RECENT DEVELOPMENTS IN PRECONCENTRATION USING DENSE MEDIA SEPARATION
The primary advantages of using a dense medium cyclone arise when only a single stage separation is required allowing for a simpler circuit and reduced cost (i.e. the dense medium cyclone is generally less expensive). INDUSTRIAL APPLICATIONS While dense media separation is used extensively in the coal industry and somewhat commonly inMagnetite can be used to form dense media with densities in the range of 1.3–2.0 g/cm 3. More dilute suspensions become unstable, whereas higher-density suspensions are too viscous to enable efficient particle separation and medium recovery ( Osborne, 1988 ). Typical magnetite particle size is in the range of 10–60 μm.Separating Density an overview ScienceDirect Topics
