Coal is a combustible black or brownishblack sedimentary rock, formed as rock strata called coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.
ADVERTISEMENTS: Coal: Types and Uses of Coal! Coal is a black or brown rock, consisting mainly of carbon, which is formed by the compressed vegetative remains of past ages. ADVERTISEMENTS: Much of the presentday high quality coals were deposited during carboniferous era,, about 300 million years ago. More recent deposits of Tertiary age are [.]

· However, selected coal deposits could be highly enriched in uranium. In this study, 15 coal samples were collected from Eastern Yunnan coal deposits, China, aiming to characterize the distribution and the occurrence of uranium in those coals. In studied samples, uranium content varied from to μg/g, with an average value of μg/g.
· In the Appalachian Coal Basin, the emission factors for bituminous coal range from a low of pounds of carbon dioxide per million Btu in Ohio to a high of in Maryland. (12) Pennsylvania anthracite, which is produced in small amounts, has the highest emission factor .
· The paper analyzes a process of deep mineralization of various metamorphic grade coals preground in different destructive units, namely, in centrifugalplanetary mill and disintegrator. Coal dispergation in higher energy intensive mills greatly enhances inorganic component extraction to acidic solutions. This is explained by distortion of crystal structure and amorphization of minerals .
