The dry separation methods for coal beneficiation have been regaining attention in the past decades. A number of improved or newly designed devices have been developedone of them is a negative pressure pneumatic separator NPPS. The said method of separation is based on the differences in the physical properties between coal and gangue minerals, such as the grain density, size, and shape.
May 23, 2017 Flotation is carried out at low solids, usually under 10 dilution. In the U. S. on bituminous coal the trend is toward open type No. 30 Sub-A Cells, single overflow, and with supercharging. Flows of dilute pulp up to 1500 GPM are effectively treated with excellent results through a single 4-cell machine.
Clean Coal Dewatering The 13-0.5mm clean coal in pit is first dewated by bucket elevator, secondly dewated by centrifuge machine, and then transported to the clean coal storage yard by belt conveyor as the final product together with the clean coal on the screen. Flotation The overflow from the pit enters the flotation feed pool and is pumped to the pulp preprocessor through the slurry pump.

Since density of clean coal particles that mostly contain organic matter is in a range from 1.2 to 1.5 and the densities of most common coal minerals are much above 2.0 density of pyrite is 5.2, the separation of coal particles into various density fractions can easily be performed in dense liquids.
A coal dense medium separation DMS plant makes use of the principle of density separation to upgrade mined coal and produce metallurgical coal or power station coal. The objective of the DMS plant operation is to produce coal product within a minimum quality specication and maximum possible yield England et al., 2002. Meyer and Craig
Modern coal cleaning technologies include Dense Medium Separation DMS, cyclones and spiral concentrators. DMS exploits the difference in density that exist between the valuable and non-valuable portions of the mined ore. With DMS, very accurate density separation can
Floatex Density Separator is a high capacity hindered settling classifier for separating particles based on size andor density. Versatile in operation, the units can be sized to treat from 1 tph to 600 tph. Performance of a traditional wet-gravity separation circuit is greatly improved with the introduction of a Floatex unit and at less cost.
Coal particles of density well below the density of separation and mineral particles of density well above the density of separation report to their proper products clean coal and refuse. But as the density of separation is approached, the proportion of the misplaced material reporting to an improper product increases rapidly.
Gravity-based separation with maximum efficiency. Developed with your entire minerals processing plant in mind, the REFLUX Classifier RC separates fine particles based on a difference in density or particle size. The RC combines a conventional fluidised bed separator with a set of parallel inclined plates that form lamella channels.
Density separation and deligniting. Almost all sand and gravel plants in the Netherlands suffer from wood or lignite particles in the sand and gravel. So over the years we built a vast experience with the available methods and equipment all over Europe. Furthermore, density separation is also used in many recycling projects.
