Depending on its quality, coal needs to be washed with water and chemicals to remove sulfur and impurities before it can be burned in a power plant. Coal washing, or coal beneficiation, is widely seen as an efficient method for getting the most from run-of-mine coal. On the other hand, it is a water-intensive process typically, washing ...
In summary, an increase of 1 ton per man-shift in underground coal mining productivity, if achieved now, would save the nation 6.89 billion between now and 1985 in prices paid for coal in noninflated 1975 dollars. A decrease in productivity costs more than an increase saves.

Feb 14, 2018 Burning this coal is inefficient because evaporating the moisture consumes roughly 7 of the fuel input. An alternative is to dry the coal before burning it, which has been found to improve plant efficiency by reducing the fuel input. It also reduces emissions including sulfur dioxide, mercury, nitrogen oxide, and carbon dioxide.
