A typical dense medium type coal preparation plant included dense medium vessel circuitry for the "coarse" raw coal, dense medium cyclone circuitry for the "intermediate" size fraction with a spiral (or water-only cyclone) circuit for raw coal down to about 0.15 mm Ultra-fines (0.15 mm x 0) were either discarded to refuse or processed ...
What Is Coal Preparation? • Coal preparation is the removal of undesirable material from the Run-of-Mine (ROM) coal by employing separation processes which are able to differentiate between the physical and surface properties of the coal and the impurities. Through coal preparation…
The systems are popular and, as of April 2011, more than 430 plants (or 70% of the Chinese coking coal washing capacity), were using Guohua technology. The systems integrate multiple technologies based on two types of core products: a gravity-fed, heavy-media cyclone and an associated heavy media cyclone for fine coal separation.

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.
Like the heavy-media vessels, Heavy-media Cyclones also are designed to clean coal and minerals based on their density differences. Using finely ground magnetite and water as the media to create a buoyancy effect for gravimetric separation, the Heavy-media Cyclone forces the lighter solids to its centre, where the slurry transports them upward and through the vortex finder.
gravity of separation has to be maintained in both heavy media vessel and heavy media cyclone circuits to improve the overall plant yield by at least 1.2%, or an additional 20 tph of clean coal. The recommended specific gravities of separation for the heavy media vessels and heavy media cyclones are 1.72 and 1.54, respectively.
The Peters Heavy Medium Vessels operate on a simple float-sink principle, which allows for the most efficient means of separation of +1/4" raw coal available. Our largest H.M. Vessels are capable of handling more than 650 ton/hour of Raw Coal, and capable of …
Magnetic Separator. Magnetic separator is widely used in coal preparation and mineral processing with particle size is between 0-20mm, to recovery heavy particle in coal preparation plant, and remove iron ore in non-metallic processing. Heavy media content: 87-130kg/m³. Recycling Rate: >99.7%. Rotation Speed: 14mrp. Magnetic Intensity: 180/300mt.

Heavy Media Gravity Separation Heavy media gravity separation involves using a mixture of fine media material, such as magnetite (SG 5.1) or ferrosilicon (SG 6.8), suspended in a slurry of water, to produce a media slurry with a specific gravity that will allow low density material(s) to float, and other high density material(s) to sink.
The new West Elk prep plant has a raw feed capacity of 700 tons per hour (tph). It is a heavy-media plant and employs a heavy-media vessel for primary separation. Taggart Global constructed the plant. Peabody Energy's Bear Run prep plant is a heavy-media plant with a 1,600 tph raw feed capacity.

A four-circuit plant investigated in this study uses heavy-medium to clean all of the coal coarser than 1 mm. A heavy medium vessel (HMV) is utilized to clean the plus 16 mm size fraction along with a heavy medium cyclone (HMC) cleaning the 16 × 1 mm size fraction of the run-of-mine coal.
Coal Preparation Plant ... Brandon Geer, Mechanic, had performed some routine repairs on a feeder and heavy media vessel, as well as taken some specific gravity readings to ensure normal plant operation. Geer exited the plant at ground level some time after 10:00 a.m. Geer walked to the hoist well of the plant to take the man lift back to the ...
By adding a heavy-media vessel and improving the fine coal circuit, Cumberland River Coal's Pardee preparation plant (in Wise County, VA) increased raw feed capacity with minimal disruptions.
Heavy media vessels. Our Lo-flo dense media vessels are designed to separate coal from refuse using a very gentle medium flow to simulate laboratory sink-float performance. The use of low quantities of media results in the lowest possible system cost. Machine size depends upon the amount of float coal product or on the amount of sinks refuse.

Coal preparation. As explained above, during the formation of coal and subsequent geologic activities, a coal seam may acquire mineral matter, veins of clay, bands of rock, and igneous intrusions.In addition, during the process of mining, a portion of the roof and floor material may be taken along with the coal seam in order to create adequate working height for the equipment and miners.
