IGBR trade activities for metallurgical coal is spread across Australia, USA, Europe, Russia and South East Asia. Our customers for metallurgical coke remain in South East Asia.

Metallurgical coal is dark and hard. It is used for energy and heating by its carbon content and caking ability. It is harder and blacker and contains more carbon and less moisture and ash than low-rank coals. When converted to coke, a pure form of carbon, it is used in basic oxygen furnaces. The degree of coal and its caking ability is determined by the volatile matter, degree of metamorphism, mineral impurities and the ability of the coal to melt, swell and resolidify when heated.
