Abstract:A selective reduction volatilization (SRV) process developed by the authors could remove excessive tin from the complex tin-bearing iron concentrates. But it was especially noteworthy that the volatilization ratio of Sn and the residual tin content were obviously influenced by the variation of roasting parameters during the SRV process. Hence, the existence form of residual tin in the roasted products and the possible reactions between SnO2 and Fe3O4 need to be further determined. In the present study, the effect of roasting parameters on the reduction of SnO2 in the tin-bearing iron concentra
