What Is A Dry Coal Washery Process

HOt Products

Washery Bharat Coking Coal Limited

Introduction: Coal Washing is a process of separation mainly based on difference in Specific Gravity of Coal and associated impurities like Shale, SandStones 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/Middlings is dispatched
