Bituminous coal, or black coal, is still relatively soft in comparison to anthracite, containing a tarlike substance called bitumen or asphalt. It is of higher quality than lignite coal (it contains more carbon) but of poorer quality than anthracite. Black coal is usually the result of high pressure being exerted on lignite.
contact usCoal is a black or brownish-black sedimentary rock that can be burned for fuel and used to generate electricity is composed mostly of carbon and hydrocarbons, which contain energy that can be released through combustion (burning). Coal is the largest source of energy for generating electricity in the world, and the most abundant fossil fuel in the United States.
contact usCoal properties vary depending on how much carbon is in the coal (coal rank). Black coal is so called because of its colour; it varies from having a bright, shiny lustre to being very dull, and from being relatively hard to soft. The term ''black coal'' is used in Australia to refer to anthracite, as well as bituminous and sub-bituminous coals.
contact uscoal - coal - World distribution of coal: Coal is a widespread resource of energy and chemicals. Although terrestrial plants necessary for the development of coal did not become abundant until Carboniferous time (358.9 million to 298.9 million years ago), large sedimentary basins containing rocks of Carboniferous age and younger are known on virtually every continent, including Antarctica (not ...
contact usBituminous: Bituminous or "soft" coal formed when greater pressure was applied to subbituminous 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 subbituminous, but less than that of anthracite. Bituminous coal averages 24 million Btu per ton.

Coal compositions span a wide continuum that is conventionally divided into four classes by gravimetric energy and carbon content (in decreasing order): anthracite, bituminous, sub-bituminous and lignite.

contact us· Regarding this, what minerals are in anthracite coal? It has a carbon content of over 87% on a dry ash-free basis. Anthracite coal generally has the highest heating value per ton on a mineral-matter-free basis. It is often subdivided into semi-anthracite, anthracite, and meta-anthracite on the basis of carbon content.
contact us· Bituminous coal is a relatively hard coal that contains bitumen, between lignite and anthracite. The calorific content of the bituminous ranges from 21 to 30 million Btu / t (24 to 35 MJ / kg). Lignite. Lignite is a mineral coal that is formed by compression of the peat. Compression makes it a crumbly substance.
contact us· Coal is a carbon-containing rock formed by the debris from the decay of ferns, vines, trees and other plants which flourished in swamps millions of years ago. Over time, the debris became buried and the actions of bacteria, heat and pressure transformed the debris first into peat (a precursor of coal) and then into the various types of coal as we know them today.
