Direct reduction (DR) processes produce different types of reduced solid iron, such as sponge iron (DRI) or hot briquetted iron (HBI). The annual production is less than a hundred of million tons (86 Mt in 2017 [26]), but it is an attractive option to reduce CO 2 intensity with promising prospective [21]. More than 80 % of the direct reduced ...

This is a coal-based reduction technology, applicable to both steel mill waste and iron ore fines, with coal as a C-reductant agent. The reduced iron can be fed to a BF or directly into a melting process. If exposed to air for a long time, the metallic iron reoxidizes into iron oxide, deteriorating its quality.
