摘要:
为高效回收铅、锌，采用化学分析、矿物自动分析等方法对新疆某氧化铅锌矿石进行了工艺矿物学研究。研究结果表明：矿石中主要可回收元素铅品位为 2.55 %、锌品位为 18.86 %，伴生元素银品位为 40.88 g/t；含铅矿物、含锌矿物、石英、菱铁矿之间的共生关系比较复杂，采用常规的浮选法回收难度较大，建议采用硫氧混合浮选铅—铅尾矿硫酸浸锌联合选冶工艺回收铅锌。本研究可为同类矿石选矿提供借鉴。

Abstract:
To effectively recover lead and zinc, a process mineralogical study was conducted on oxidized lead-zinc ore using chemical analysis and mineral liberation analysis based on their occurrence status in the ore. The resultsshow that the ore contains 2.55 % Pb and 18.86 % Zn, with a silver content of 40.88 g/t as an associated element. Theore exhibits a complex intergrowth relationship among lead‑bearing minerals, zinc‑bearing minerals, quartz, and smith‑sonite, making conventional flotation methods difficult to apply effectively. A combined process involving sulfide-oxidemixed flotation of lead followed by acid leaching of zinc from the lead tailings is recommended for lead zinc recovery.This study provides a valuable reference for the beneficiation of similar ores.
