| Abstract: | In this paper,the present state and shortage of utilization of dusts bearing Zn Pb from metallurygical plants are summaried; a new theory and a new method of separation of Zn Pb from the dusts are davanced;The best process parameters show:aluminium bath smelting reduction with a reduction temperture of 1 100℃ ,reduction time 45min,nature basicity,binder 0.5%,no or little C powder is needed.ZnO conent of volatile matter is over 90%(the best gets up to 92.52%),PbO content is less than 5%;the Zn volatilization rate and Pb enrichment rate are up to 90%. |
