There are many varieties of coal, ranging from anthracite, bituminous, lignite, peat to brown coal, but the unique caking ability of metallurgical coal makes it different from other forms of coal. Moreover, the sole property of coking coke makes it an unreplaceable ingredient in the steel manufacturing industry.

Anthracite, which represents the highest rank of coal, was formed in the coalification process when fossil sedimentation was subject to high pressures over millions of years. Anthracite has the highest content of fixed carbon and the lowest ratio of volatile matter of all natural coal types.

Because of anthracite's high carbon content, it burns cleaner than other types of coal (c.f. lignite) and therefore emits less toxic compounds upon combustion Anthracite is the superior choice of coal and is the ideal material as a carbon source, with applications from the foundry all the way to the desalination plant.

Anthracite is a high-rank coal, representing a coal that has been subjected to the highest grade of metamorphism. Anthracite is shiny black, hard and brittle (see Figure 2.8) and has the highest fixed-carbon content (approximately 86–98%).Due to its low volatile matter (2–12%), anthracite's combustion process is slow.

Anthracite Coal – this coal is of highest rank. It is higher in carbon and very low in volatile matter (less than 10 percent). It exhibits a semi metallic luster and burns without smoke. Its carbon content is nearly more than 87 percent on a …

By definition, bituminous coal contains less than 86 percent fixed carbon while anthracite contains 86 percent or more fixed carbon. Because of the difference in their relative levels of carbon, each of these types of coal is used very differently. Bituminous coal is mostly burned in order to generate electricity.

Anthracite differs from ordinary bituminous coal by its greater hardness (2.75–3 on the Mohs scale ), [12] its higher relative density of 1.3–1.4, and luster, which is often semi-metallic with a mildly green reflection. It contains a high percentage …

Bituminous coal accounted for about 45% of U.S. coal production in 2020. Anthracite contains 86%–97% carbon and has a heating value that is slightly higher on average than bituminous coal. Anthracite is the least abundant rank of coal in the United States, and it generally accounts for less than 1% of annual U.S. coal production.

Explanation: Anthracite coal is a higher grade than bituminous coaland is formed under greater pressure and at higher temperatures. Anthracite coal contains more carbon than bituminous coal and less sulfur, making it more desirable. Bituminous coal also contains more moisture than anthracite coal.

It's a compact coal and has fewer impurities than any other type. Containing between 92% and 98% carbon it has the highest carbon content of any coal as well as the highest energy density of any coal apart from graphite. Anthracite coal comes in standard, high and ultra-high grades which can all be burned in smoke control areas.

Anthracite coal is sometimes referred to as "hard coal." Anthracite coal is a highly carbonated fossil fuel that produces the most heat of any fossil fuel on the market, and its low sulphur content makes it a very clean-burning fuel. Bituminous coal is also known as "soft coal," while anthracite is known as "hard coal."
