To meet demand of coking coal for HSL Steel Plants, Central Coal Washeries in the vicinity of existing Marshaling yards of Kargali, Durgapur, Dugda, Bhojudih and Patherdih were envisaged; and Kargali Washery was commissioned in 1958 by NCDC as first public sector washery in India.
a need for setting up a coal washery to upgrade this coal to make it more suitable for industrial use. Production of coal from this washery will help to bridge the gap of demand and supply of coking coal in India. Benefits at regional level The project will create employment opportunities both for skilled and semi skilled persons in the area.
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.

Introduction: Coal Washing is a process of enrichment of combustibles in coal by removal of noncombustible impurities utilizing industrial separators mainly based on difference in Specific Gravity of Coal and associated impurities like Shale, Sand Stones etc. so that we get marketable coal suitable for the target consumers. The Washed Coking Coal is meant for Steel Plants.
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.
MANUFACTURING PROCESS COAL WASHERY This section comprises of coal crushing and screening and washing of coal to produce clean coal with 34% ash, appropriately sized and a middling fraction by treating the ... DESCRIPTION OF ENVIRONMENT Base line data has been collected on ambient air quality, water quality, noise levels,
Introduction Coal mining is one of the most significant worldwide mining activities due to high electricity and heat production demands. The current known coal reserves in 2020 were estimated to be approximately billion tons.
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.

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.
The chapter gives a holistic view of coal from its geological occurrence, mining methods, washing techniques, general description of coal washery and its operations, quality monitoring, instrumentation and control, problems encountered in operations, and their troubleshooting techniques.

coalfields of SECL. In the process of coal washing large amount of coal rejects and fines are generated. To effectively utilize the coal rejects and fines, a power plant of 2 X 135 MW capacity is proposed near the washery at about 6 km distance. This will result in savings in the cost of rejects fines transportation and enhance solid
The coking coal resources can be augmented by recovering extra low ash coking coal from washery middlings by suitable beneficiation processes (Jha, 2012).This possibility has been established from tests. The middlings were crushed to 13 mm and 3 mm and thereafter subjected to float and sink tests. The results are presented in Figure (a).
The coal beneficiation or coal preparation process separates inorganic impurities from raw mined coal, reducing the concentration of unwanted material or gangue and thereby providing improved combustion characteristics to the fuel produced. The commonly used beneficiation methods for coal sorting and processing include jig separation, heavy ...
Thirteen Coal Washries to be set up by Coal India. Posted On: 04 APR 2022 4:59PM by PIB Delhi. 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.
