Coal is the most abundant fossil fuel. India is blessed with huge coal reserve, nearly 7% of total coal in the world. 85% of this reserve is non coking coal, which caters to the need of power, cement and sponge iron plants. However, most of these reserves are of very low grade coal and the reserves of good quality coal is fast depleting. On the other hand, the demand for coal is increasing due to higher demand of steel, power and cement. The problem of inferior coal is further aggravated due to extensive mechanised mining. As a result, the users of coal is not getting desired
quality necessitating beneficiation of coal for use in cement plant, sponge iron kiln, power plant etc.
M/s. Chhattisgarh Power & Coal Benefication Ltd., who are a reputed group trading Coal for Power, Cement and Sponge Iron industries, intends to change the Beneficiation Process of their existing 1.25 MTPA Fluidized Bed Bath type Coal Washery at Sirgitti, Bilaspur to Heavy Media Cyclone Process to cater to the requirements of their various customers. The washery shall be of 1.25 MTPA (250 TPH) capacity and shall beneficiate F Grade coal of around 45% ash of Korba area.
The Coal Washery shall be environment friendly with effective Dry Fog type Dust Suppression System to prevent emission of fugitive dust. The washing process shall be with close circuit water system comprising Heavy Media Cyclone, Classifying Cyclones, High Frequency Screen & Thickener.

INFRASTRUCTURE
For establishment and successful operation of a coal washing plant it is imperative to ensure availability of the following infrastructure :
Availability of principal raw materials, viz., Raw Coal, and its proximity to the plant to reduce cost of transportation.
Road / Rail head connection so that raw materials and products can be easily and economically transported.
Permanent and reliable source of power. Source of water. Land for Plant installation, storing of products and disposal of rejects.
Since the raw material shall be required in bulk quantities, the location of the plant shall be nearest to the mines to save in transportation cost and to ensure consistent supply of raw coal. Necessary road connection is already available between the plant site and nearby coal mines.
Power supply can be easily met from the grid. Sufficient land required for setting up of coal washing plant is available at the plant
