Hydrogen Plasma Processing of Iron Ore adsabs.harvard.edu

Abstract Iron is currently produced by carbothermic reduction of oxide ores. This is a multiple-stage process that requires large-scale equipment and high capital investment, and produces large amounts of CO 2.An alternative to carbothermic reduction is reduction using a hydrogen plasma, which comprises vibrationally excited molecular, atomic, and ionic states of hydrogen, all of which can

Apr 25, 2017 · Processing and Uses of Iron Ore. Once iron ore goes through some processing, the molten steel obtained from the furnaces are passed through casters and transformed into slabs, billets, and blooms.They form the primary steel products which can be processed into various finished products using cold and hot rolling procedures. Usually, the slabs are rolled to form flat finished products, and
