Product Overview


A hard, compact variety of coal with a high luster, Anthracite is known for having the highest carbon content, fewest impurities and the highest calorific content of all the various types of coal.

The most metamorphosed type of coal, it features a carbon content of between 92.1-98%. It features three separate grades: standard, which gets used mainly in power generation, while both high grade and ultra high grade are primarily used in the metallurgy sector.

It differs from the more ordinary bituminous coal by having a greater hardness, higher relative density, and a luster that is often a semi-metallic with a mildly brown reflection. Anthracite coal also goes by the names black coal, hard coal, and stone coal.


Thermal Coal Specification Parameters


Anthracite is a hard, high-grade coal that produces a hot blue flame when burned. Most anthracite in the U.S. comes from Pennsylvania, where it was heavily mined in the late 1800s and early 1900s. Anthracite has become more difficult to mine because the remaining reserves are deeper and deeper underground.

Anthracite is ideal for generating heat in coal-burning furnaces in homes or small businesses. Not only does anthracite burn hotter than other coals, but it also burns more slowly and is the most efficient heat producer relative to its weight. Anthracite is the cleanest burning coal, and when used properly in modern furnaces will require little cleaning.



Bituminous, or “soft” coal, is so named because it contains bitumen, a tar-like material. Bituminous coal is lower quality and easier to mine than anthracite. It is burned to produce electricity and run trains. Bituminous coal can produce excessive soot and smoke when burned, so it’s not ideal for heating, especially in coal or wood-burning stoves in the home.

Bituminous coal is also used to produce coke and to make iron and steel. Anthracite is not commonly used for blacksmithing because, unlike bituminous coal, anthracite produces small pieces of coke that tend to blow up and out of the fire. As a result, bituminous coal is better suited for blacksmithing. Blacksmith coal used in forges is high-quality bituminous coal, although some forges may use coke or charcoal.




Lignite, or “brown coal,” is the lowest quality coal. Geologically, it is the youngest type of coal. According to the Lignite Energy Council, about 79% of lignite coal is used to generate electricity and 13.5% is used to generate synthetic natural gas, while 7.5% is used to produce fertilizer products (including anhydrous ammonia and ammonium sulfate). Lignite produces little heat relative to its weight compared to other coals, so it is usually used to generate power in plants near the mine. Because only a very small percentage is used domestically (typically for heating or fertilizer), lignite is not covered by our list of coal suppliers and dealers.





Coal slag is the byproduct of coal that is burned to create power. Slag can be made into blasting abrasives that are cleaner and safer than silica sand (which is another common blasting abrasive). Producers of this material clean the slag and sort it by size — medium, fine, and extra fine — before selling to consumers. Abrasive blasting involves using high pressure to propel abrasive material, such as coal slag, onto a surface either to smooth a rough surface, roughen a smooth surface, or to clean the surface.
