Abstract

The Indian coking coal reserves are less compared to the non-coking coals and the good quality coking coals have been exhausted leaving behind poor quality feed stock for the metallurgical sector. For production of Iron & Steel through blast furnace route, coking coal is an important raw material. The good quality coking coals of the upper seams are fast depleting leaving behind the inferior quality lower seam coals which are low volatile coking in nature and available in Jharia and East Bokaro Coalfields. These coals are characterized by high raw coal ash content and poor washability characteristics. CSIR-CIMFR had carried out extensive studies on the washability characteristics of these LVC coals and based on the data generated, an attempt has been made to develop a flow sheet for washing these coals at 18% clean coal ash content.
