Classification of Coal. Coal can be classified into the following types according to the composition and stage of formation: Peat (the first stage with 30 per cent carbon content). Lignite or Brown Coal (the second stage with 30 per cent to 40 per cent carbon content). Bituminous Coal (the third stage with 40 per cent to 80 per cent carbon ...

Coal classification Coal is classified into three types as follows, even there is no clear demarcation between them: 1. Anthracite 2. Bituminous 3. Lignite. The Coal is further classified as semianthracite, semibituminous and subbituminous. the anthracite is the oldest coal from a geological perspective.
Coal Classification There are two main ways for classifying coal by rank and by type. Coal Rank Coal Types Coal Rank : The degree of ''metamorphisrn'' or coalification undergone by a coal, as it matures from peat to anthracite This has an important bearing on its physical and chemical properties, and is referred to as the ''rank'' of the coal.
