Coking coal

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).
