Anthracite is a type of sedimentary rock which is hard and is variety of coal that has high luster
From Greek anthrakites, from anthrax, anthrak meaning coal
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
In Chemical and Pharmaceutical Industry, Manufacture of Aspirins
Alumina Refineries, Electricity Generation, Liquid Fuel, Manufacture of Soap, Solvents, Dyes, Plastics and Fibres, Paper Industry
Semi-anthracite and Meta-anthracite
Helps in production of Heat and Electricity, Used as fossil fuel
Anthracite forms from the accumulation of plant debris in a swamp environment. When plant debris dies and falls into the swamp, the standing water of the swamp protects it from decay.
