Anthracite is referred to as a "hard coal" due to its high carbon content, typically ranging from 86% to 97%, which contributes to its strength and density. Its formation under high pressure and temperature over millions of years leads to a low volatile matter content, making it one of the purest forms of coal. This unique composition results in a clean-burning fuel that produces minimal smoke and pollutants. Additionally, its lustrous appearance is another characteristic that distinguishes anthracite from other coal types.

What anthracite is so hard and pure it is also referred to as?
Anthracite is so hard and pure that it is also referred to as "black diamond." It has a high carbon content and is considered the highest quality coal due to its low impurities and high energy density. Anthracite burns cleanly and efficiently, making it a popular choice for heating and industrial applications.
Why is Anthracite coal is so hard and pure it is also referred to as a?
Anthracite coal is very hard and pure because it has undergone intense pressure and heat over millions of years during its formation, making it the most metamorphosed type of coal. Due to its high carbon content and low impurities, anthracite is often referred to as a "metamorphic rock" rather than a typical coal.
What type of coal is harder than bituminous or anthracite?
bituminous is less hard,and its dull.whereas anthracite is very hard.
How are bituminous coal and anthracite coal alike?
Bituminous coal is relatively soft and dull, as opposed to anthracite which is hard and shiny. Anthracite is also much more dense and pure. Because of its purity (can be up to 98% carbon), Anthracite burns a very hot, smokeless flame.
What is coal mainly made up of?
Carbon. Coal has a few different types and grades, but hard anthracite coal is almost pure carbon. Same as graphite, soot and diamonds.

Is coal ingeous?
No.It is sedimentary, however anthracite is considered metamorphic. Graphite (chemically pure carbon) can be found in igneous rocks.
What are forms of lignite and anthracite?
Peat is decayed vegetation probably thousands of years old but which has not been converted to coal. Lignite is called brown coal, again vegetable matter that has not become true coal. Anthracite is a very pure form of coal much valued for steam engines.
What fuel is mined from the earth that is almost pure carbon?
Coal, particularly anthracite coal, is almost pure carbon.
