Anthracite, also known as hard coal and black coal, is a hard, compact variety of coal that has a submetallic lustre.
What is anthracite used for
It has the highest carbon content, the fewest impurities, and the highest energy density of all types of coal and is the highest ranking of coals.
The Coal Region of Northeastern Pennsylvania in the United States has the largest known deposits of anthracite coal in the world with an estimated reserve of seven billion short tons.[2]China accounts for the majority of global production; other producers include Russia, Ukraine, North Korea, South Africa, Vietnam, Australia, Canada, and the United States.
Total production in 2020 was 615 million tons.[3]
Anthracite is the most metamorphosed type of coal, but still represents low-grade metamorphism,[a] in which the carbon content is between 86% and 97%.[1]
