ores is an attractive option in that it does away with si ntering, which is a dirty process, and replaces expensive coke with cheaper reductan ts. Not having a sintering plant and coke ovens saves on costs and emissions. Fluidizedbed reactors, both bubbling and circulating, are being used in the direct reduction of iron ore [6–8].

Iron ores can be formed of several different minerals; the most common are hematite and magnetite. DSOs, including the midgrade products Rio Tinto and BHP produce from Australia's Pilbara region and the highgrade 65% Fe fines Vale produces in Brazil, are predominantly hematite products.
