STUDY ON THE ORE DRESSING TECHNOLOGY OF OXIDE LEAD-ZINC ORE FROM XITIESHAN

This paper discussed the oxide lead-zinc ore of Xitieshan and found reasons why it was difficult to deal with the oxide lead-zinc ore by means of ore dressing. The technological flowsheets, the flotation condition, the open-circuit experiment and the closed-circuit experiment were determined based on systematic study on the ore -dressing. The result of the closed-circuit experiment showed that using GS-1 as the collector, CaO+ZnSO 4 as the depressant and NaCO 3 as the dispersant, the result can be showed as following: the production percent of Pb concentrate 5.59%, the grade of Pb concentrate 45.26%, the recovery rate of Pb concentrate 72.48% , the production percent of Zn concentrate 13.64%, the grade of Zn concentrate 45.71%, and the recovery rate of Zn concentrate 74.78%. It has some developing value.
