Lignite: Lignite coal, aka brown coal, is the lowest grade coal with the least concentration of carbon.
What is the difference between lignite and coal?
Lignite is often called “brown coal” because it is lighter in color than the higher ranks of coal. It has the lowest carbon content out of all the coal ranks (25%-35%)1 and it has a high moisture content and crumbly texture.
