| Abstract: | In order to study the feasibility of recovering iron precipitate slag from zinc smelting process with side-blown fuming furnace, the effects of coal powder consumption, Fe2O3/SiO2 ratio and CaO/SiO2 ratio, reaction temperature and time on the smelting process were investigated. The optimal processing parameters were finally determined. With coal powder and slag sample at a mass ratio of 1∶2.8, CaO/SiO2 ratio of 0.75, Fe2O3/SiO2 ratio more than 1, fuming at 1 250 ℃ for 1 h, the volatilization rate of lead and zinc exceeds 96%. |
