Coal - Wikipedia


Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams.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.

Is Coal a Rock, Mineral or Fossil? - thoughtco.com


Aug 20, 2019· In the process, the coal releases methane or natural gas. Anthracite, a shiny, hard black stone, is nearly pure carbon and burns with great heat and little smoke. If coal is subjected to still more heat and pressure, it becomes a metamorphic rock as the macerals finally crystallize into a true mineral…

Coal Beneficiation Process Diagram


Many breakers and washeries efficiently handle the coarser sizes, but waste the coal fines. This problem is assuming major importance due to the increase in the amount of coal fines being produced by the mechanization of coal mining. Flotation offers a very satisfactory low-cost method for recovering a fine, low ash, clean coal product at a profit.

Mining Industry Profile | Department of Energy


The U.S. mining industry consists of the search for, extraction, beneficiation, and processing of naturally occurring solid minerals from the earth. These mined minerals include coal, metals such as iron, copper, or zinc, and industrial minerals such as potash, limestone, and other crushed rocks. Oil and natural gas extraction (NAICS code 211) is not included in this industry.

Coke (fuel) - Wikipedia


This process vaporizes or decomposes organic substances in the coal, driving off volatile products, including water, in the form of coal-gas and coal-tar. The non-volatile residue of the decomposition is mostly carbon, in the form of a hard somewhat glassy solid that cements together the original coal particles and minerals.
