The utilization of non met coals for production of liquid hot metal was the motivation for the development of the COREX Process by VAI/DVAI during the 70`s. Like the conventional ironmaking route (coke oven/blast furnace) it is based on coal as source of energy and reduction medium. However, in difference to blast furnace, coal can be used directly without the necessary prestep of cokemaking. Coking ability of coals therefore is no prerequisite of suitability. Meanwhile the COREX Process is on its way to become established in ironmaking industry. COREX Plants at ISCOR, Pretoria/South Africa and POSCO Pohang/Korea, being in operation and those which will be started up during the next years comprise already an annual coal consumption capacity of approx. 5 Mio. tonnes mtr., which is a magnitude attracting the interest of industrial coal suppliers. The increasing importance of COREX as a comparable new technology forms also a demand for information regarding process requirements for raw material, especially coal, which is intended to be met here.
