Treatment Plant for Clean Environment M K

2016-7-20  Working Principle of Washery Coal washing is mainly based on the differences in specific gravities between the coal and impurities present in the coal. Since most of the impurities are heavier than the coal itself the coal is separated from its impurities by designed uses of these differences. Specific gravity of pure coal is between 1.23 to 1.7.

Coal Beneficiation Technology for Coking Non-Coking

2016-5-14  Abstract: There are 21 coking coal washeries in production both in private and public sectors. Production of clean coal in these washeries during 1989-90 was 12 million tonne and it is expected to go up to 37 million, tonne during 2015-16. Planning Commission has taken the decision that non-coking coal meant for Thermal Power Plants situated far away from feeding coalfield, should be beneficiated. 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. The Washed Power Coal/Washed Non-Coking Coal/Middling is dispatched to various Power Houses. The Coal Washery Rejects are the major environmental hazard during the process of Coal Washing.
