Dry Beneficiation of Coking Coal Fines using an Advanced Air Cyclone

Srikant, Satya Sai; Mahapatra, Rajendra Prasad; Rao, Raghupatruni Bhima


An attempt is made on coking coal fines dry beneficiation of below 2 mm size, with VSK separator consisting of advanced air cyclone. The results of these investigations reveal that simple size with 250 micron can give a product with 18% ash at 17.4% yield, whereas by using VSK separator the product obtained contains 17.8% ash with 48.1% yield from a feed sample containing 23.3% ash. Since the preliminary investigations has shown encouraging results on reduction of ash, large scale continuous tests can provide better yield for various samples.
