Anthracite is a hard, compact variety of mineral coal that has a high luster. It has the highest carbon content, the fewest impurities, and the highest calorific content of all types of coals, which also include bituminouscoal and lignite.

Anthracite is a type of coal that is known for its high carbon content, low moisture content, and high energy density. It is considered the highest grade of coal due to its purity and high heat output. Anthracite is a hard, shiny, black rock that burns cleanly with little smoke or odor. It is typically used for heating homes and buildings, as well as in industrial applications such as power generation and steel production. Anthracite is more rare and more expensive than other types of coal, but it is valued for its efficiency and cleanliness when burned.

It is the hardest coal and has semi metallic lustre. It is the purest form of coal which contains about 94-98 % carbon. It's moisture content is very low and thus it is also known as smokeless coal.
