Coal preparation is the removal of undesirable material from the RunofMine (ROM) coal by employing separation processes which are able to differentiate between the physical and surface properties of the coal and the impurities. Through coal preparation, a uniform product is achieved. Washability Study

The coal industry serves a vital role in the nation's economy by producing fuel for more than half of its electricity. Despite the industry's importance, industry financial data for 2005—the strongest year for the coal industry in recent years—shows that it is a relatively small industry with revenues totaling 20 billion to 25 billion and net income between 1 billion and 2 ...

States has far more coal than gas and petroleum (compare Figures 71, 81 and 91). This suggests that, when supplies of gas and petroleum become scarce, it would be possible to turn to coal as our major fossil fuel energy resource. How long could we rely on domestic supplies of coal? There are many uncertainties involved in making such an ...
