    Recovery of Fine Combustible Matter from Coal Washery

    Feb 24, 2007 A process for the recovery of fine combustible matter from coal washery waste using four-inch and two-inch hydrocyclones and MGS was then proposed. The yield, combustible matter recovery, calorific value and ash content of concentrate obtained from the process were 37 %, 57 %, 5940 kcal/kg and 18 %, respectively.

    Hydrocyclones Weir Group

    Hydrocyclones, also known simply as ‘cyclones’, are an effective means to selectively concentrate slurry particles through a separation and classification process. This simple process separates the slurry mixture, with the larger mass particles leaving through the hydrocyclone underflow and the water and fines exiting through the ...

    hydrocyclones required. Clusters of hydrocyclones may also be used to remove oversize grits from cement, clay, drilling mud, effluent and other slurries, as well as de-sliming duties. Dense Media separation Linatex Hydrocyclone G4 DM is widely used in the coal, iron ore and diamond industries for dense media separation (DMS);

  • Heavy media Cyclones for coal cleaning FLSmidth

    Heavy media Cyclones for coal cleaning FLSmidth

    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.

    Washability an overview ScienceDirect Topics

    The behavior of coal in density-based cleaning processes can be predicted from a series of float-sink (or washability) tests carried out on a crushed sample in the laboratory.The sample is placed in a heavy liquid of known density (e.g., 1.40 g cm − 3) and the floating fraction skimmed off for weighing and analysis.The sinking fraction is then placed in a liquid of somewhat higher density ...

    Derrick HI G dryers help in dewatering of coal washery

    the washery, and dewatered solids are taken to a storage yard for disposal/sale. In the plant, tailings from washery are pumped to the plant where hydrocyclones are used for separating solids at 0.15mm and thickening to 50 percent solids. Thickened solids are dewatered using six HI-G Dewatering machines, and the -0.15mm fraction is sent for
