Coal Classification | General | Lignite |

Lignite: Also termed brown or rosebud coal. It is considered the lowest rank of coal. As lignite ages, it becomes darker in color and harder in texture. The new product is termed sub-bituminous coal. Bituminous coal: This coal is high in carbonaceous matter and is divisible into high-volatile, medium and low-volatile groups on the basis of increasingcoal classification | Types & Facts | Britannica,Coal classification: Coal classification, any of various ways in which coal is grouped. Most classifications are based on the results of chemical analyses and physical tests, but some are more empirical in nature. Coal classifications are important because they provide valuable information to commercial users and to researchers.Classification of Coal - Engineering ToolBox,Classification of coal based on volatile matter and cooking power of clean material
