Every coal does not possess all the desired specific properties and composition strictly required for making quality coke for the blast furnace. India owes a vast reserve of coal to the tune of over 301 billion tonnes out of which only 12.67% are coking coal in nature (2.1% prime coking, 9.9% medium coking and 0.67% semi coking) (Coal

A second issue regarding froth flotation, especially that of ultra-fine coal, is whether or not it would be economically viable to 'de-slime' the feed to the cells. Ultra-fine coal has a very large surface area per unit mass, approximately 53 000 m2/ton. During flotation, the surface of the coal particles needs to be coated with a collector and
