Steel production is dependent upon coal and coke in steelmaking. Metallurgical coke, or met coke, is manufactured from blends of bituminous coal in a heated distillation process resulting in a non-melting carbon. Coke is made by one of two processes: by-product or non-recovery, also known as heat recovery.
Coal is made largely of carbon but also features other elements such as hydrogen, oxygen, sulfur and nitrogen. Coal starts off as plant matter at the bottom of water. It is eventually covered and deeply buried by sediments where over time metamorphosis (a change in form) takes place.Different types of coal contain different amounts of carbon. Lignite contains only around 60 to 75%, while anthracite contains more than 92%.oal starts off as plant matter at the bottom of water.
