It has the highest carbon content, the fewest impurities, and the highest calorific content of all types of coal, which also include bituminous coal and lignite.

Deeper burial and the passage of time result in further expulsion of moisture and volatile matter, eventually transforming the material into higher rank coals such as bituminous and anthracite coal.

Characteristics Lignite is brownish black in color and has a carbon content of around 25 35 , a high inherent moisture content sometimes as high as 66 , and an ash content ranging from 6 to 19 compared with 6 to 12 for bituminous coal.

It is now known that efficient processes that remove latent moisture locked within the structure of brown coal will relegate the risk of spontaneous combustion to the same level as black coal, will transform the calorific value of brown coal to a black coal equivalent fuel while significantly reducing the emissions profile of 'densified' brown coal to a level similar to or better than most black coals.

Coal is extracted from the ground by coal mining, either underground by shaft mining, or at ground level by open pit mining extraction.

But, when Romney talked about increasing coal production, Obama neglected to point out that carbon dioxide from coal fired electricity generation is already a major contributor to climate change that we still lack the technology to produce clean coal and that increasing the use of coal will impose huge burdens on people worldwide.
