Glossary - U.S. Energy Information Administration (EIA)

Acid mine drainage: This refers to water pollution that results when sulfur-bearing minerals associated with coal are exposed to air and water and form sulfuric acid and ferrous sulfate. The ferrous sulfate can further react to form ferric hydroxide, or yellow boy, a yellow-orange iron precipitate found in streams and rivers polluted by acid ...

Rare Earth Elements from Coal, Kentucky Geological …

Rare Earth Elements from Coal. Coal and coal preparation products are also potential sources of rare-earth elements. REEs are a group of elements (shown in purple on the periodic table below) unknown to most people. They include the lanthanide series elements (cerium through lutetium), yttrium, and scandium. Although relatively unheard of, rare ...

Environmental Costs of Extracting Mineral Resources

The aesthetic costs of strip mining, the occupational health hazards associated with coal mining and the acid leached into streams from mine operations are all examples of associated environmental costs. The cost of extraction and sale (including user cost) is borne by the resource owner and taken account of (internalized) in the calculation of ...

Coal: Anthracite, Bituminous, Coke, Pictures, Formation, Uses

Sub bituminous coal has a heating value between 8300 and 13000 British Thermal Units per pound on a mineral-matter-free basis. On the basis of heating value, it is subdivided into sub bituminous A, sub bituminous B, and sub bituminous C ranks. Bituminous. Bituminous is the most abundant rank of coal.

Coal-fire minerals and tars. Minerals and tar frequently deposit on the mouth of coal-fire vents, and are formed through isochemical and mass-transfer processes (Stracher, 2007). Samples were collected from each fire; the minerals were identified using X-ray diffraction (XRD), and the tars were characterized using organic analyses.

Report on Rare Earth Elements from Coal and Coal Byproducts

Fossil Energy (FE) explored the potential of coal and coal byproducts as viable sources of Rare Earth Elements (REE). A series of activities to assess REE resources associated with major coal basins in the U.S. were conducted. Over 1800 samples, representing approximately 30,000 individual REE analyses, were taken from various sources.
