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.

new dense-medium cyclone plant at Tertre in Belgium to process 10 x 0 mm raw coal. The plant was unique in that the feed to the plant was not de-slimed before processing. The raw coal was mixed with magnetite and gravity-fed to two 500 mm diameter (D) cyclones at a feed pressure of 9D. The minus 0.75 mm coal in the feed drained through

Raw coal was deslimed in a cyclone and screen dewatered leaving a fraction 0.5 - 0.075mm. This was mixed with heavy medium and pumped to a separating cyclone 150mm in diameter. Magnetite was recovered in a series of magnetic separators. The clean coal was thickened in a cyclone and screen dewatered. MAGNETITE DATA •1980.
A dense medium cyclone (DMC) effects a sharper separation than can be obtained in other types of coal-washing equipment handling the same size range, usually 50–0.5 mm size range. For hard-to-clean coal (+ 10% near gravity material) in the size range of 50 mm to 0.5 mm, DMCs are very effective.

When you need magnetic separation the Reading range of magnetic separators has a wide range of proven, cost effective products. Including wet high intensity, induced roll, rare earth roll, rare earth drum, low intensity and medium intensity magnetic separators the Reading range has a magnetic solution to fit your particular processing requirements.
Leeuwpan fine coal dense medium plant mixed with magnetite in the launder and enters a second stage washing cyclone. The product of the secondary cyclone is sent to a product magnetic separator and the discard of the primary cyclone is routed to the discard magnetic separator. The discard of the secondary washing stage is recycled back to the feed.
The medium is not homogenous with respect to fine size coal 2. The forces operating on fine particles inside the cyclone are too weak with respect to fluid resistance These problems can be eliminated by the use of heavy organic liquids or micronized magnetite In South Africa and USA, recent dense medium cyclones are used without desliming.

Heavy medium cyclones make use of a medium which is a homogenous mixture of water and dispersed magnetite. Density of the medium is regulated by adjusting the amount of magnetite in the mixture. Coal is mixed with the medium in a sump and fed to the HMC where the heavier ash material is separated from lighter coal due to density differences.
Magnetite Uses - Education - Micrex Development Corp- what is magnetite used for in a coal washing plant,When used as the aggregate portion of a concrete mix, magnetite increases the concrete" has become a common building material in nuclear plants as well as (in counter weights for everything from washing machines to pipeline anchors to Magnetite is an essential part of the "heavy media ...
Dense medium cyclones. A cyclone is a conical vessel in which coal along with finely ground magnetite (media) is pumped tangentially to a tapered inlet and short cylindrical section at a predetermined flowrate and pressure followed by a conical section where the separation takes place.
XSD Sand Washer. The efficient sand washing machine of XSD series is a kind of cleaning equipment of international advanced level for sand and slag pellets, developed on the basis of introducing foreign outstanding technology of the same kind of products.
Coal preparation plant - Wikipedia - what is magnetite used for in a coal washing plant, A coal preparation plant is a facility that washes coal of soil and rock, crushes it into graded A ROM stockpile is used to allow the washplant to be fed coal at lower, constant rate. Dense medium gravity separation methods use a material such as magnetite ...
magnetic separators and cyclones in the magnetite plant in the foreground and the concentrator flotation area in the shed behind. What is magnetite? Magnetite (Fe3O4), like hematite (Fe2O3), is a form of iron ore. It is a benign and highly magnetic substance used primarily in steel manufacturing and coal …
Tungsten powder is added to the sodium polytungstate solution to raise the SG further, and is used for separation SG's between 3.3 and 4.0. The first step of the HLS test is to prepare the ore sample to mimic that which will feed the DMS
Dense medium cyclone (DMC) is widely used to upgrade run-of-mine coal in the coal industry. The flow within it is very complicated, with four phases (water, air, fine magnetite and coal) involved.
Magnetite increases the density of most mixtures in which it is present. This property allows magnetite to be used in the manufacture of heavy concrete, water filtration, coal mining, landscaping and production of certain iron-based chemicals.
A computational fluid dynamics (CFD) model of the dense medium cyclone (DMC) has been developed, using Fluent, by coupling component models for the air-core, the magnetite medium and coal particles.
