Lignite coal usually contains 40%–55% carbon.It is a soft brown coal that still contains a high amount of moisture.This is lower grade coal.

Bituminous coal contains 45%–86% carbon. It is most widely available and used.It is a dense, compact, and is usually in black colour.

Anthracite coal contains 86%–97% carbon and generally has the highest heating value of all ranks of coal. It is hard and dark black in color,and has very light weight when compared to other forms of coal, as there is very little moisture present in it.It is the highest grade of coal.
