Coal washeries that dispatched washed coal to power plants received a total of raw coal from the mines. The washing process at washeries reduces the ash content of the raw coal and out of which a total of MT washed coal was produced and dispatched to the power plants in . Eastern and Central regions have been processed ...
Balance equations as well as process control equations in the model ensure that coal which is mined from the coalfields is equal to that transported to the washeries and power plants, power generated from all plants in a region is equal to the sum of the regional power demand and transmission loss, quantities output from each washery relate to the input quantities, washery yields, as well as ...
feed coal is reduced from 42% to 34% and to 24% respectively. Total project cost of such plant including cost of coal washery and AFBC for using washery rejects at ash content at 42%, 34%, 24% is likely to be cheaper by 5%, 8% and 10% respectively. Generation of 15 to 18 MWe by AFBC is an extra benefit. Larger gains may be
In Coal India Limited (CIL) has plan to set up 12 new coking coal washeries and one noncoking coal new washery to reduce the quantity of ash and useless component from coal. All these washeries are expected to be operational by FY:2026. Details of new washeries set up or planned in CIL are as under:

JHARIA REJECTS. Tata Steel coal washery rejects are produced as byproducts from its Jamadoba and Bhelatand Coal Preparation Plants. In both the plants, coal washery rejects are mixed with middlings to produce the end product '2PR or 2Product Rejects' as a part of the process. Quality of 2PR ranges from G13 to G17 equivalent of CIL coal grade.

A process flow route was developed for the generation of MFFD, which has now been patented by the company. The ball millhydrocyclone circuit generally used in coal washeries for grinding magnetite can be used to generate the MFFD with slight modifications. However, close control of the size distribution of the MFFD is required.
The notification which was issued on May 21, 2020, stated that the process of coal washing leads to extensive pollution. "Ash generated during washing pollutes water and cannot be gainfully utilized. The process involves increased water use, effluent generation, fugitive dust and the disposal of washery rejects has negative environmental ...

Hence it cannot be washed by the process which involves water as a principal media (as density of water is 1). Henceforth the media should have density within the range of so as to separate good quality clean coal from the reject coal. Therefore MCWPL has established a coal washery based on Heavy Media Process.
