摘要:A novel selective reduction roasting process has been successfully developed for utilizing the complex tin, zinc-bearing iron concentrates by the authors' group. In this study, the isothermal reduction kinetics of SnO2 and ZnO in the preheated iron ore pellet containing tin and zinc was investigated in a 20%CO–80%CO2 gas mixture at temperatures of 950 °C, 1000 °C, 1050 °C and 1100 °C. It was found that the reduction reaction of SnO2 → SnO (g) was controlled by interfacial chemical reaction at 950 °C and 1000 °C, whereas it was controlled by combination of chemical reaction and gas internal dif
