The process of coal formation is still taking place today, says Bailey. “The precursor to coal is called peat, and that is just uncompressed plant matter.” Peat accumulates in wet swampy environments known as mires, and that process is taking place today in areas such as Indonesia and even the Antiplano in the Andes.

Which coal has lowest ash content?

Anthracite is the highest ranked coal with the carbon percentage of above 87%. The carbon content in bituminous is 77-87%, in sub-bituminous is 71-77% and in lignite is 60-70%. Lignite has the least carbon content and hence highest ash content.
