Iron Ore Reduction an overview ScienceDirect Topics

The research on the reduction of iron ore has received much attention in the past few decades as a result of the increasing cost and low availability of raw materials. The reduction of gaseous emissions and the search for low-cost alternatives to traditional routes has also boosted the investigations for reduction processes ( Plaul et al., 2009 ).
