This is a coalbased reduction technology, applicable to both steel mill waste and iron ore fines, with coal as a Creductant 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.
