To begin with, the chemical composition of coal is analyzed by proximate and ultimate analyses (ASTM, 1993 ). Proximate analysis determines by using set procedures regarding moisture, volatile matter, fixed carbon, and ash content ( Figure 5.21 ).

Centuries of coal mining in Appalachia have left a wake of destruction behind. Thousands of former mine sites still pose health and safety risks, and the extensive environmental damage includes polluted waterways, compromised groundwater, and the loss of 1.5 million acres of forest in one the most biologically diverse temperate ecosystems on the planet.

Coal is slightly denser than water (1.0 megagram per cubic metre) and significantly less dense than most rock and mineral matter (e.g., shale has a density of about 2.7 megagrams per cubic metre and pyrite of 5.0 megagrams per cubic metre). Density differences make it possible to improve the quality of a coal by removing most of the rock matter
