Anthracite forms from the metamorphism of bituminous coal. It undergoes intense pressure and heat over millions of years, which causes the coal's carbon content to increase and its impurities to decrease. This process results in anthracite's high carbon content and low impurity levels, making it a hard and clean-burning type of coal.
bituminous is less hard,and its dull.whereas anthracite is very hard.
Anthracite coal, which is a harder and more carbon-rich coal with a higher energy content.
Anthracite is the hardest form of coal. It has a high carbon content and a low moisture content, making it a high-quality fuel source with a high energy output.
Anthracite coal is formed by the further metamorphism of bituminous coal. This process involves high pressures and temperatures, which leads to the coal becoming harder and more carbon-rich. Anthracite coal is the highest rank of coal and has a high carbon content and low impurities.
Anthracite is a hard, black form of coal that has a high carbon content and low volatile matter compared to other forms of coal. It is used primarily as a fuel source for heating and in industrial processes due to its high energy content.
Anthracite is a form of coal. It is hard black and shiny.
Anthracite is a form of coal. It is hard black and shiny.
Anthracite is a form of coal, coal is primary carbon, and carbon is black.
Anthracite, also known as anthracite coal, is formed through metamorphism. Anthracite needs pressure to form, as well temperatures of at least 250 degrees Celsius.
Anthracite is a form of high quality coal. It is entirely natural.
Anthracite is a form of coal, which is a fossil fuel, and is thus non-renewable.
anthracite coal is the metamorphic form of bituminous coal which is the sedimentary form. in other words it has been heated under pressure.

ANTHRACITE : a hard form of coal produced by long-term heating and pressure. Pronounced "ANN-thruh-syte" (rhymes with "pushed down tight")
