3. LigniteLignite is a relatively young coal deposit that was not subjected to extreme heat or pressure.Lowest rank of coal with the lowest energy content.Lignite is crumbly & has high moisture content.About eight percent of the coal produced in the United state.Mainly found in Western U. S.
4. SubbituminousSubbituminous coal typically contains 35-45 % C, compared to 25-35 % for lignite.Thus it has a higher heating value than the lignite.Over 40 % of the coal produced in the united states is Subbituminous Mainly found in Western U.S.
5. Bituminous CoalBituminous coal contains 45-86 % C, & has two to three times the heating value of lignite.It has most abundant rank of coal found in the united states, accounting for abut half of US coal production.Bituminous coal has a high sulfur content & thus is the Lowest Grade US coal deposit.
6. AnthraciteAnthracite contains 86-97 % C, & its heating value is slightly higher than bituminous coal..Highest grade Coal in US.Low amount of Sulfur makes this a clean burning coal.Anthracite is very rare in the US (2% of overall production.)
