Coal is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers called coal beds
From the Old English term col, which has meant mineral of fossilized carbon since the 13th century
Coarse Grained Rock, Fine Grained Rock, Medium Grained Rock, Opaque Rock
Black, Brown, Dark Brown, Grey, Light to Dark Grey
Cement Manufacture, for Road Aggregate, Making natural cement, Steel Production
Alumina Refineries, Electricity Generation, Liquid Fuel, Manufacture of Soap, Solvents, Dyes, Plastics and Fibres, Paper Industry
Peat, Lignite, Sub-Bituminous Coal, Bituminous Coal, Anthracite, Graphite
Helps in production of Heat and Electricity, Used as fossil fuel
Coal forms from the accumulation of plant debris in a swamp environment which is buried by sediments such as mud or sand and then compacted to form coal.
