of coal resources and is the third largest coal producer in the world with a production of 572.37 million tonnes in 2010-11. India's coal production has risen from 70 million tonnes in early 1970 (Ministry of Coal, 2011) to 692 million tonnes in 2016 (Wikipedia) with an average growth rate of around 5% (Figure 1.2).

Coal beneficiation is one of the most effective methods for removing minerals (such as gangues and pyrite) and pollutants (such as sulfur) before the burning of coal. In general, the beneficiation process of low rank coals is more difficult to achieve than that of bituminous and/or anthracite coals. However, about 50% of the world's total …

The cylinder played a significant role in desliming of the feed, giving the secondary cyclone a better gravity-separation condition. Ash reductions of +0.150 mm fractions were all above 70%, which showed that the cyclone had significant effects on fine coal separation in the classified gravity system.

Coal Beneficiation. Coal beneficiation is a process by which the quality of raw coal is improved by either reducing the extraneous matter that gets extracted along with the mined coal or reducing the associated ash or both. Two basic processes of beneficiation: Dry-deshaling: Non-coal or shaly-coal is removed without using any liquid media.

A small amount of medium, fed from a splitter box, is added to the feed sump to make up the coal/medium volume to the required amount for pumping to a second-stage 400 mm dense-medium cyclone. The overflow of the secondary (Floats) cyclone constitutes the product coal and is gravitated to a static drain screen.

Abstract and Figures. The dense medium cyclone (DMC) process used in coal beneficiation plants is studied from a control system perspective. Employing the …

The separator provides a stable density environment for the effective separation of raw coal. Three products consisting of 73.25% pure clean coal with an ash content of 9.59%, 11.31% middlings, and 15.44% gangue were effectively separated from raw coal at a high density of 1.82 g/cm3 and a low density of 1.57 g/cm3.

The price paid for the coal is US$ 21 per ton F.O.B. Richards Bay, based on a 6 000 kcal / kg product. The price is adjusted on a linear scale for higher quality coal. The price for 6 100 kcal/kg coal is thus US$ 21,50 and for 6 200 kcal/kg coal, US$ 22. Railage is paid by the colliery on the tonnage of coal railed at a rate of R45/ton.
