中文摘要: 随着硫化铅矿资源的不断开发与消耗,氧化铅矿的高效开发与利用已成为保障我国铅需求量的重要途径。针对云南腾冲地区氧化铅矿,其主要含铅矾、白铅矿和少量方铅矿,含Pb4.54%,本文采用硫化-黄药法深度硫化后再利用混合捕收剂进行浮选,分析讨论了磨矿细度、药剂种类、用量等因素对铅矿物富集效果的影响。研究结果表明,当原矿磨矿细度为-200目80%时,浮选闭路试验获得品位和回收率均较高的铅精矿产品,铅精矿含Pb64.50%,Pb回收率90.74%,分选指标较好。本研究可为类似铅矿资源的选矿开发利用提供一定的技术依据。

Abstract:With the continuous development and consumption of lead sulphide resources, the efficient development and utilization of oxided lead ore has become an important way to ensure the demand for lead in China. This paper is aimed at the oxygen-sulfur mixed lead ore in the Tengchong area of Yunnan. The lead minerals are mainly lead bismuth, leucite and galena, containing 4.54% Pb. It is determined that the vulcanization-xanthate method is used for deep vulcanization and then mixed collector flotation. In the process, the effects of grinding fineness, dosage and dosage on the enrichment of lead minerals were studied. When the ore grinding fineness is -200 mesh 80%, the flotation closed-circuit test can obtain lead concentrate products with higher grade and recovery rate. The lead concentrate contains Pb64.50%, Pb recovery rate is 90.74%, and the sorting index is better. This study can provide a certain technical basis for the development and utilization of similar ore resources.
