How (and Why) to Value a Coal Mine
All coal is not equal; it is not a homogenous product. Coal is categorized according to its physical and chemical properties — such as hardness, energy content and moisture level. Harder, thermal coal (such as anthracite) or higher energy content coal mainly is used for steel manufacturing and industrial fuel; coal with a higher...
