Coal is broadly separated into brown and black which have different thermal properties and uses. Brown coal (lignite) has a low energy and high ash content. Brown coal is unsuitable for export and is used to generate electricity in power stations located at or near the mine. Black coal is harder than brown coal and has a higher energy content.

Modern Alchemy Russian Scientists Discover How to Extract
