what is s and sub bituminous coal

Bituminous - The bituminous coal contains very little moisture, and is harder than both sub-bituminous and lignite coal Anthracite - It is the hardest coal with highest carbon content, and lowest moisture and ash content The quality of anthracite is much higher than bituminous, sub-bituminous, and lignite...

Bituminous coal

Bituminous coal or black coal is a relatively soft coal containing a tarlike substance called bitumen or asphalt It is of higher quality than lignite coal but of poorer quality than anthracite Formation is usually the result of high pressure being exerted on lignite...
