摘要：Calcite (CaCO3), one of the main impurities, has an uncertain effect on the volatilization behavior of tin oxide in the tin-bearing iron ore concentrates during the selective reduction volatilization process. In this study, natural calcite powders were added into the tin-bearing iron ore concentrates to investigate tin volatilization behavior affected by CaCO3 under different roasting temperature, CO content, and roasting time. In addition, the effect of CaCO3 on the phase transformation of SnO2 was determined using XRD, SEM-EDS combined with thermodynamics calculation.
