WASHERY
Introduction:
Coal Washing is a process of enrichment of combustibles in coal by removal of non-combustible 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. The Washed Power Coal/Washed Non- Coking Coal/Middlings is dispatched to various Power Houses.
