Metallurgical Coal

There are two types of coal, metallurgical coal and energy coal. Metallurgical coal has the metallurgical properties to produce coke, which is used to make iron within a blast furnace, the dominant steel-making technology.

As a critical ingredient within efficient steel production, metallurgical coal is a material that ultimately contributes to the affordable construction of high-rise buildings and other key infrastructure such as bridges.

We produce premium-quality, hard-coking coal for steelmaking at our Illawarra Metallurgical Operation in New South Wales, Australia.

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 low-cost metal, particularly in buildings, infrastructure, vehicles and machinery.
