| 摘 要： | 某低品位氧化铅锌矿含铅3.42%、含锌2.93%, 矿石中有用矿物嵌布粒度细且回收难度较大。为了合理开发利用此矿石, 进行了硫化-黄药浮铅闭路工艺流程试验。在六偏磷酸钠用量500 g/t、碳酸钠用量1 000 g/t、硫酸锌用量1 000 g/t、硫化钠用量2 000 g/t、2#油用量100 g/t、戊基黄药用量500 g/t的粗选条件下进行闭路试验, 最终获得氧化铅精矿铅品位为33.12%、回收率为68.89%, 实现了铅的有效回收。

| Abstract: | Dressing technique for a low-grade lead-zinc oxide ore containing 3.42% Pb and 2.93% Zn was studied. As valuable minerals are finely disseminated in the ore and are difficult to be separated out, a closed-circuit flowsheet consisting of a sulphidization and a lead flotation with amyl xanthate as the collector was introduced. Under the following reagent system for roughing process, including hexametaphosphate of 500 g/t, sodium carbonate of 1 000 g/t, zinc sulfate of 1 000 g/t, sodium sulfide of 2 000 g/t, 2# oil of 100 g/t and amyl xanthate of 500 g/t, a lead oxide concentrate with Pb grade and recovery of 33.12% and 68.89% respectively can be obtained, indicating that lead minerals therein recovered effectively. |
