Metallurgical coal, also known as met and coking coal, is a naturally occurring sedimentary rock found within the earth's crust. Met coal encompasses a wide range of quality grades including hard coking coal, semihard cokingcoal, semisoft coking coal and pulverised coal for injection (PCI). All are used to make steel.

Metallurgical coke sounds like a soda beverage, but it's not. It is a refined carbon product made from a special kind of coal. Using extremely high temperatures, coal can purified into coke which is then used in the iron and steel making processes. One of the most important steps in the cokemaking process is choosing the right coal to use ...

Metallurgical Coal. Metallurgical coal is an essential ingredient in blastfurnace steel production and accounts for around 70% of global steel output. Also known as coking coal, this carbonrich form of coal is used to make coke which is the primary source of carbon used in steelmaking. The coal is sourced through mining. Mineral Processing

Metallurgical Coal What is Coal? Click to Learn More Coal formation began during the Carboniferous Period known as the first coal age which spanned 360 million to 290 million years ago. Coal is a fossil fuel and is the altered remains of prehistoric vegetation that originally accumulated in swamps and peat bogs.

Chemicals from Coking Metallurgical Coal. Most of the chemicals derived from coal come from byproducts produced during the coking process. Coal is used to make coke to make steel. Coke gas (also called foul gas) contains coke tars, ammonia, and light oils. Tars are recovered and used to make tar derivatives. Ammonia is recovered as an aqueous ...

Higher coking coal prices increase the cost penalty incurred by steelmakers, leading to higher price penalties for lowgrade iron ores (Exhibit 2). This could affect overall iron ore price dynamics in two different ways, depending on the level of total iron ore demand. In one scenario, if total demand for iron ore can be met solely with high ...

05/2008 Metallurgical Industry Coke Production General Metallurgical coke is produced by the destructive distillation of coal in coke ovens. Prepared coal is heated in an oxygenfree atmosphere (coked) until most volatile components in the coal are removed. The material remaining is a carbon mass called coke.
