摘要: 西部某氧化铅锌矿石矿物组成复杂,次生氧化矿多,选别难度大。探索试验表明锌难以分离富集,因此着重进行了铅的分选试验。针对矿石性质及矿物可浮性,在多段硫化浮选工艺中恰当引进重选作业,获得了铅品位为47.66%,含锌3.49%,铅回收率为70.28%的铅精矿,实现了矿石中铅的回收。

Abstract: The oxide lead-zinc ore from west China is characterized by complex mineral composition, many secondary oxidized minerals and difficult beneficiation. The explorative test indicated the difficulty in zinc separation and therefore, the stress was laid on the lead separation. In light of the ore properties and mineral floatability, a gravity separation was introduced properly in the multi-stage sulfidization flotation process. As a result, a lead concentrate with a 47.66% lead grade, 3.49% zinc and 70.28% lead recovery was obtained, realizing the lead recovery from this ore.

Key words: Oxidie lead-zinc ore, Multi-stage sulfidization flotation, Gravity separation.
