Kinetic studies of the blast furnace dust (BFD) reduction process have been carried out under non-isothermal temperature condition. BFD pellets were made with bentonite as the binder. A Comprehensive Thermal Analyzer (TG-DSC) was used to determine the mass loss of pellets, which were heated at three heating rates of 10, 20, 30 K/min up to 1 493K. Furthermore, the metallization rate and mineral composition of BFD pellets heated to several different temperatures were analyzed by chemical analysis and X-ray diffraction (XRD). It was found that, with its inherent carbon resources as the reducing agent, the metallization rate of BFD pellets could reach 88% at most. The reduction and weight loss process of iron oxides mainly happens above 1273K. In addition, it was obtained from Coats-Redfern equation that the apparent activation energy of the reduction from wustite to Fe is 443kJ/mol and the mechanism function is interface reaction mechanism R2.
