Conflating Queenslands Coking and Thermal Coal Industries
Coking coal is predominantly used in steelmaking as a reductant (to convert iron oxide into metallic iron), as a carbon source to produce heat, and in the blast furnace to support the burden (preventing the iron ore and fluxes from collapsing into the liquid iron). Queensland is the world's largest supplier of seaborne coking coal globally,
