    Abstract:

    Using sulfur-bearing stone coal, the tin could be removed efficiently from cassiterite, But it was especially noteworthy that the volatilization ratio of tin was influenced by the ferrous sulfate in sulfur-bearing stone coal. Hence, the effects of ferrous sulfate on the reduction behavior of cassiterite need to be further studied. A new method for calculating the phases and phases formation temperature using FactSage software is described in this study. Ferrous sulfate and coal were used as reductants and a wide range of addition amounts were covered. The phases of roasted cassiterite with different proportions of reductants calculated by FactSage were consistent with those analyzed by XRD. The change trends of the equilibrium Sn amount calculated by FactSage also agreed well with those of onset of roasting measured by various analyses, i.e. XRD and chemical analysis. This new method is less labor-intensive and less costly compared with XRD and chemical analysis. Moreover, it also can provide prediction of roasting temperature range and proportions of reductants for tin remove from cassiterite.
