Metallurgical or coking coal is a primary ingredient in the steel making process. More than twothirds of global steel is produced in basic oxygen blast furnaces. China is the largest consumer of premium coking coal in the world. Coking coal, generally known as metallurgical coal, is a naturally occurring sedimentary rock.

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.

Coal is a crucial ingredient in the processing of iron ore. Metallurgical coal is heated to create coke, which is then added to a blast furnace with iron ore, producing pig iron. That pig iron is then used to make steel. Steel is widely used as a strong and lowcost metal, particularly in buildings, infrastructure, vehicles and machinery.

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 ...

Metallurgical coal (also called "met" coal) is an important raw material used in the steelmaking process, although very small amounts of coal (relative to the amount used for electricity) are needed. The coal used to make steel is heated without air in an oven at temperatures of as much as 2,060°F (1,125°F), until most of its volatile matter is released.
