The techniques adopted for the study have formed a guideline to remove the suspended solids from other coal washery effluent in the area. Detailed description of the invention The coal washeris are most major contributors of pollutants to the river Damodar. The coal washery effluent contains extremely high amount of suspended solids.

Use of coal at the same time raises environmental concerns. The impacts of increased coal utilisation will have increased environmental impacts from emissions of air pollutants during coal mining, coal transportation and coal combustion, contamination of the surface and ground water, forest loss due to mining, etc.

Technological Options 9 Clean coal technology being practised in coal washeries in India, as precombustion clean coal technology, mainly focus on cleaning of coal by removing ash from coal 9 Earlier only coking coal was being washed because steel making needs coking coal of ash of 17 to 18%.
Figure 1: Opencut/underground coal mining facility process diagram . Figure 1. is a generalised facility process diagram for opencut coal mining. In general opencut mining occurs in layers as material is excavated over a period of time. The main activities carried out at opencut coal mines that could lead to emissions to air,
At the washery, illustrated by flowsheet "A," the entire mine output is sold for coking coal. Mining the relatively narrow seam produces a product with 15 to 20% ash, although the coal when cleaned will carry only 3 to 3½% ash. This low ash coal brings a premium price, so it is an economic necessity to remove the impurities ...
After thermal upgrading, the coal is put through a deep bed stratifier cleaning process to separate the pyrite rich ash from the coal. When fed a typical low rank western coal, the SynCoal process can provide a product with a heating value of up to 12,000 BTU/lb with moisture and ash contents as low as 1% and %, respectively [ 100 ].
Coal washing is accomplished by one of two major processes, by density separation or by froth flotation. Both processes depend on the fact that the particles of which a coal sample are made have different densities. When water, for example, is added to the sample, particles sink to various depths depending on their densities.
Although a minor portion (<15%) of the losses might have been avoided, process performance was in most cases up to standard. The majority of losses can be attributed to deficiencies in various aspects of the technology, arising ... Summary of clean coal losses in washery reject (197880) 60 26. Some variables affecting probable error, yield ...
Tata Steel's Jharia division commissions 2MTPA coal preparation plant at Jamadoba. Built from cuttingedge technology, the 2 MTPA coal preparation plant has been transformed from the oldest running washery in Asia (in operation since 1952) to one of the most modern washeries across the globe

1. ROM Coal MTPA Coal will be sourced from SECL mines namely Deepka, Gevra, Kusmunda and other mines [on DO basis] Manufacturing Process Coal washery comprises of coal crushing screening and washing of coal to produce clean coal with ash content less than 34%. Wet type of coal washery is proposed as it will have
PROJECT DESCRIPTION Process Description The proposed coal washery will be a Heavy Media Bath based coal beneficiation unit. The proposed coal washery has been divided into three sections: a. Prewashing Unit: A dry crusher circuit which can be called as the prewashing circuit. b.
Coal is a combustible black or brownishblack sedimentary rock, formed as rock strata called coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is a type of fossil fuel, formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.
Classification of Coal. Coal constitutes a heterogeneous mixture of transformed organic vegetal matter and associated inorganic materials. It is rich in carbon and mineral matter. Coalification refers to the series of processes involved during the transformation of this organic vegetation into coal.
The calorific value of the available deposits of Indian coal is in the range of 4000 to 5000 Kcal/Kg (UHV 2500 to 4000 Kcal/Kg) as compared to about 6000 Kcal/Kg of imported coal. This is due to inherent quality of the deposits. It is not cost effective to wash and improve the quality unless the coal has to be hauled a long distance.
