  • Carbothermal Reduction Of Iron Ore In Its Concentrate

    Mar 16, 2017 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 reduce iron.This paper presents the results of a study on carbothermal reduction of iron ore made under the microwave field in equipment specially developed for this purpose. The equipment allows the control of radiated and reflected microwave power, and therefore measures the microwave energy actually applied to the load in the reduction process.
