About :
* Coal is a fossil fuel and is the altered remains of prehistoric vegetation that originally accumulated in swamps and peat bogs.
* The quality of each coal deposit is determined by : varying types of vegetation from which the coal originated; depths of burial; temperatures and pressures at those depths; and length of time the coal has been forming in the deposit.
* Coking coal is a high-quality coal that is low in impurities and has a high carbon content, which makes it ideal for use in the metallurgical process.
* Coking coal is used to produce coke, which is a porous, solid carbon material that is used as a fuel and a reducing agent in the production of iron and steel.
* Largest coal-producing countries in the world:
China (3.7 billion tonnes),
India (783 million tonnes),
United States (640 million tonnes),
Indonesia (616 million tonnes)..
