The principal use of anthracite today is for a domestic fuel in either hand-fired stoves or automatic stoker furnaces. It delivers high energy per its weight and burns cleanly with little soot, making it ideal for this purpose. Its high value makes it prohibitively expensive for power plant use.
Where can anthracite be found?
Anthracite is the least plentiful form of coal. In the United States it is found mostly in northeastern Pennsylvania and makes up less than 2 percent of all coal reserves in the country. Smaller amounts of anthracite occur in South Africa, Australia, eastern Ukraine, western Canada, China, and other countries.

What is the difference between coal and anthracite?

How do you identify Anthracite?
Anthracite differs from ordinary bituminous coal by its greater hardness (2.75–3 on the Mohs scale), its higher relative density of 1.3–1.4, and luster, which is often semi-metallic with a mildly brown reflection. It contains a high percentage of fixed carbon and a low percentage of volatile matter.
How long does anthracite take to form?

How does anthracite form?
Anthracite coal forms when bituminous coal undergoes very low grade metamorphism, accompanied by structural deformation. The fixed carbon content under these conditions reaches 85-95%. If anthracite is metamorphosed further it turns into graphite.
How long does anthracite last?
