WhatsApp: +86 18203695377Introduction: 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.
