A coal preparation plant (CPP; also known as a coal handling and preparation plant (CHPP), coal handling plant, prep plant, tipple or wash plant) is a facility that washes coal of soil and rock, crushes it into graded sized chunks (sorting), stockpiles grades preparing it for transport to market, and more often than not, also loads coal into rail cars, barges, or ships.
Along- with the discharged water, small particles of coal are carried away to the pond where the coal particles settle down on the surface of the pond, and the same is collected after the pond is de-watered. The coal particles so collect- ed are of fine quality, ash free and the same is used as fuel.

Coal mining in India has a long history of commercial exploitation starting in 1774 with John Sumner and Suetonius Grant Heatly of the East India Company in the Raniganj Coalfield along the Western bank of Damodar River. Demand for coal remained low until the introduction of steam locomotives in 1853.

Time bound disposal of all tailings & rejects. All the washeries have been made Zero discharge; the same water is recycled again and again in the main process of the Washery. All the washeries are maintaining free board space in the slurry ponds and within its premises to check over spillage of slurry.
History of coal washing in india . Coal Preparation in India – A Historical Perspective The earliest record of systematic coal washing study in India was an attempt by Prof. William Galloway using a pre-Baum type Jig washer before World War I on tested Assam coals.
and the tailings slurry shall be transported through a closed pipeline to the tailing dam. Tailings are being disposed through closed pipe line to the earmarked Tailing dam after necessary treatment. xv The decanted water from the tailing dam shall be re-circulated and there should be zero discharge from the tailing .
Today, the universal disposal method for tailings is the tailing pond. Tailings are slurried with water and pumped to tailing ponds for settling. Frequently, tailings are cyclone-classified before deposition. Coarse sands are used to build-up the tailing dam, while the slimes are deposited inside the pond.
With a prominent emphasis on large scale mechanized opencast mining in India, large tracts of land are left degraded because of activities like excavation, stacking of waste dumps, discharge from workshops, construction of tailing ponds, etc. Underground mining operations also lead to the problem of the subsidence of land and result in changes ...
In India, broad estimates suggest that the total stock of slurry/tailing accumulated at different washeries of Coal India Ltd. (CIL), is in the tune of 3.0 million tonne. Added to this there is a regular slurry discharge of about 60,000 t/month. The factors affecting the quality of slurry pond fines are :- Parent Coal Characteristics.

Mar 21, 2014· Coal is one of the most-water intensive methods of generating electricity. A typical coal plant withdraws enough water to fill an Olympic-sized swimming pool every three and a half minutes. The International Energy Agency says that global water consumption for power generation and fuel production is expected to more than double from 66 billion cubic meters (bcm) in 2010, to 135 bcm by 2035.
