What Are the Four Stages in Coal Formation?

Mar 30, 2020· Bituminous coal is the third stage of coal production. The lignite continues receiving heavy vertical pressure until it turns a dark brown and becomes soft coal. Bituminous coal is used as an energy source in many parts of the world. The final stage of coal production is the anthracite stage. During this stage, soft coal becomes hard coal.
