Dry beneficiation of coal: A review - [email protected]

To intensify the production of coal, mechanisation of coal mining is gradually increasing. The process, being less selective, increases the quantity of shales, stones and other impurities in coal. Dry methods of separation of these impurities may serve as a preconcentration step prior to wet processes of beneficiation. Dry beneficiation will eliminate the energy intensive process

Chapter 7 COAL

The total amount of coal in the world is so large (equivalent to about 150,000 quadrillion BTU) that the possession of even a small fraction represents a major economic benefit (see Review Question 7-2). Great Britain has as little as 1%% of the world's coal, and yet it was the world's leading coal-producing nation for over a century.
