Beneficiation of an Indian non-coking coal by column

2017-8-29 Beneﬁciation of non-coking coal is gaining ground in India. It not only reduces the volume of inert content to betransported to the power plant and also lowers the wear in the boiler houses. For special applications such as the fuel forintegrated gasiﬁcation combined cycle plant (IGCC), the ash content in the coal should preferably be below 15 %. Indiancoals are characterized by high inter-grown ash content mainly due to ‘drift origin’ of Gondwana formation in Permian age.This warrants ﬁne grinding of non-coking coal in order to liberate the ash forming minerals from coal macerals. A non-coking coal sample of vitrinite type from India was ground to 44lm(d80) and subjected to column ﬂotation to improve itsquality. The non-coking coal analyzing 34.6 % ash, 26.2 % volatile matter, 1.3 % moisture and 37.9 % ﬁxed carbon couldbe upgraded to a concentrate/froth of 14.83 % ash

IMPACT OF WEATHERING ON COKING COAL MSK

Introduction: Coal can be classified as coking or non coking depending on its behavior when heated to a temperature of about 700 0 C to 1000 0 C in absence of air. If coal softens, de-volatilizes and solidifies into porous hard solid coke, it is classified as coking or caking coal.
