Coal Rejects are a byproduct of the coal washing / beneficiation process, in which after separation of beneficiated washed coal and middling, the rejects are left over as a portion of raw feed coal. These are generated from the coarse circuit of the coal washery process. No additional crushing or blending is required for its usage.
coal obtained as a product of the washery contain to per cent ash. Quantity of feed coal used was 3000 to 3500 TPD. The middlings and rejects produced were 1350 TPD and 900 TPD, respectively. The washery requires 91 kl/h for the processing which is pumped from the river. The feed water comes
Rejects are the products of coal beneficiation process after separation of cleans and / or middlings, as a fraction of feed raw coal. Used for Fluidized Bed Combustion (FBC) Boilers for power generation, road repairs, briquette (domestic fuel) making, land filling, etc.

Coal washing Coal that comes from a mine is a complex mixture of materials with a large variety of physical properties. In addition to the coal itself, pieces of rock, sand, and various minerals are contained in the mixture. Thus, before coal can be sold to consumers, it must be cleaned. The cleaning process consists of a number of steps that results in a product that is specifically suited to ...
The washery will process up to and sometimes above 200 tonnes per hour of run of mine coal. The lower the yield then the higher the input feed can be as the plant is very successful at removing large quantities of shale quickly.
Process of Coal Beneficiation: The proposed washery is wet type of coal washery, the entire process and operations to be carried out at the unit are described in brief as follows: Raw Coal Receipt and Handling Arrangement: Raw coal in the size range 2000mm, from the mines will be received by wagons at nearby railway siding.
The project started construction on 27 June, 2016 with Investment of 350 million yuan and construction period of 10 months. After completion, the main products for the election are the lump coal in 3080mm and smalls below 30 mm, and after washing the clean coal calorific value will be in 6500 kcal or more.

Coal Washing is a process of separation mainly based on difference in Specific Gravity of Coal and associated impurities like Shale, Sand Stones etc so that we get relatively pure marketable coal without changing its physical properties. The Washed Coking Coal is meant for Steel Plants.
Beneficiated noncoking coal is used by cement, sponge iron and other industrial plants; MIDDLINGS : Middlings are byproducts of the three stage coal washing / beneficiation process, as a fraction of feed raw coal. Used for power generation; Also used by domestic fuel plants, brick manufacturing units, cement plants, industrial plants, etc.
INDIAN SCENARIO OF COKING COAL PLANTS 9Prior to 1950, there were no Beneficiation plants, since selective mining was in practice. 9The first Indian coal washery was set up at West Bokaro in 1951, followed by the second one installed at Jamadoba .

the process. In addition to beneficiation of coal slurry in washery operation, the process can be utilized for recovery of the coking coal fraction from washery middlings. The tests carried out with Lodna washery middlings have similar performance parameters as with the coal slurry . The agglomerated cleans from the middlings
Coke is a grey, hard, and porous fuel with a high carbon content and few impurities, made by heating coal or oil in the absence of air — a destructive distillation process. It is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges when air pollution is a concern.. The unqualified term "coke" usually refers to the product derived from low ...
