Abstract
The presently adopted beneficiation and recovery system in the existing coal washeries produce a large quantity of coal slurry that gets settled in nearby areas. Due to high ash content, it can not be mixed with clean coal and is used for non metallurgical purposes, such as domestic coke making, brick making etc., while a significant amount goes as a waste, polluting a large extent of neighborhood areas and river. In India, broad estimates suggest that the total stock of slurry/tailing accumulated at different washeries of Coal India Ltd. (CIL), is in the tune of 3.0 million tonne. Added to this there is a regular slurry discharge of about 60000 t/month.
