Coal is a solid but brittle, carbonaceous black sedimentary rock that burns. It is made up of carbon, hydrogen, oxygen, nitrogen, and lesser amounts of sulfur and other trace elements. Coal is divided into four classes: lignite, subbituminous, bituminous, and anthracite. Of the commonly minable coals,

There are four major types (or "ranks") of coal. Rank refers to steps in a slow, natural process called "coalification," during which buried plant matter changes into an ever denser, drier, more carbon-rich, and harder material. The four ranks are: Anthracite: The highest rank of coal. It is a hard, brittle, and black lustrous coal, often referred to as hard coal, …
