Direct Reduction of Ferrous Oxides to form an Iron-Rich Alternative
Sponge iron is produced primarily both by using non-coking coal and natural gas as reductant and therefore classified as coal-based and gas-based process, respectively. High purity sponge iron powder is currently manufactured from high purity iron ore following the basic steps of magnetic separation and milling, primary reduction process, hydrogen annealing, and final milling and classification.
