| Abstract: |
| Shaanxi Zhen'ao Dingsheng Mining Limited used to use DDTC (diethyldithiocarbamate) and BX (butyl xanthate) as collectors. This reagent system encountered a bit low Pb recovery in the Pb concentrate, big fluctuation of Zn grade in Zn concentrate, high mutual containing of Pb and Zn in the concentrates and large consumption of lime which affected recycling water and environment.Since 2011, the grade of ores decreased, and the content of pyrite increased. More lime had to be used to inhibit the flotation of pyrite. BK906 and MB which might be used in weak alkaline conditions were selected to replace DDTC and BX. A small amount of BX were added into Zn middlings during Zn flotation. The production data of the past year shows BK906 and MB can increase the recovery of both Pb and Zn. The lime consumption decreases from 10kg/t to 5kg/d. |
