Is bituminous coal a mineral
This process vaporises or decomposes organic substances in the coal, driving off volatile and liquid products, including water, such as coal gas and coal tar. Coke is the non-volatile residue of the decomposition, the cemented-together carbon and mineral residue of the original coal particles in the form of a hard and somewhat glassy solid.Bituminous Coal: Great pressure results in the creation of bituminous, or “soft” coal. This is the type most commonly used for electric power generation in the U.S. It has a higher heating value than either lignite or sub-bituminous, but less than that of anthracite. Bituminous coal is mined chiefly in the Midwest & Appalachia Sub-Bituminous Coal Sub-bituminous coal is about 100 million years old. It contains more carbon than lignite, about 35-45 percent. In many parts of the world, sub-bituminous coal is considered "brown coal," along with lignite. ... or economically unimportant minerals. Toxic coal tailings can pollute local water supplies.
