What is coal? | World Coal Association

Coalification. The degree of change undergone by a coal as it matures from peat to anthracite is known as coalification. Coalification has an important bearing on coal's physical and chemical properties and is referred to as the 'rank' of the coal. Ranking is determined by the degree of transformation of the original plant material to carbon.

From coal, a new source of rare earths cen.acs

Young coal looks promising. Lignite, which is found in North Dakota and Texas, is the youngest type of coal. Young coal contains a lot of organic acids called humic acids, which chelate metals and rare earths. But over time, the humic acid concentrations in coal drop, and the rare earths get incorporated into aluminosilicate clays.

How is coal formed? Kentucky Coal Education

In the process of transformation (coalification), peat is altered to lignite, lignite is altered to sub-bituminous, sub-bituminous coal is altered to bituminous coal, and bituminous coal is altered to anthracite. Lignite is the lowest rank of coal which means that it has the lowest heating value and lowest carbon content. Although lignite is more solid than peat it crumbles when shipped long distances.
