Mechanism of Carbothermic Reduction of Hematite in Hematite–Carbon Composite Pellets
ISIJ International, 2007 Isothermal reduction experiments are carried out to study carbothermic reduction of hematite in hematite–graphite composite pellets. The carbothermic reduction is dominated by the direct reduction at the initial stage of reduction, and it is determined by the indirect reduction together with the carbon solution loss reaction when the CO partial ...
