Faculty of Land Resource Engineering , Kunming University of Science and Technology, Kunming 650093, China)Abstract : The flotation is one of the most effective methods for separation of lead and zinc from lead-zincpolymetallic sulfide ore. The difficult separation of lead and zinc is due to the similar floatability of galenaand sphalerite, the dense symbiosis and complex dissemination relationship ・ The key to solve this difficult problem is the selection and application of efficient flotation reagents ・ In this paper, the major researchadvances of lead-zinc sulfide ore collector, depressant? activator and pH value modifier are overallsummarized. The sphere of application, merits and demerits of flotation reagents are analyzed. It was pointed out that the optimization of reagent system and the development of new reagent should follow theprinciples of high efficiency, low cost and no pollution.Key words : lead-zinc sulfide ore ; flotation reagent ; separation of lead and zinc铅和锌是两种重要的有色金属,广泛应用于蓄 电池、电子、机械、焊料和放射性防护等领域。

中国目前是全球最大的铜、铅、锌消费大国,且随着经济的增长仍呈现持续上升的趋势[1-3]。
虽然中国的铜、铅、锌资源储量均处于世界前列,但主要以伴生硫化矿石为主,且嵌布粒度细,给分离带来了极大的难度[4],目前主要采用浮选方法进行综合回收[5-9],但通常存在精矿品质不高的问题。
姚家岭铜铅锌矿矿产资源丰富,铜、铅、锌、金、银等金属储量大,具有巨大的开采利用价值。
但该矿矿石性质复杂、多变,属复杂难选铜铅锌多金属硫化矿[10]。
因此制定合理的选矿工艺对其进行综合回收,具有重要意义。
