摘　　要：云南某地氧化铅矿矿物种类复杂,属于高铅低锌碱性氧化矿石。选矿工艺研究结果表明,原矿硫化后,采用自制新型捕收剂回收氧化铅比常规硫化—黄药捕收效果较好。其闭路试验可获得铅精矿品位Pb52.24%、回收率83.33%技术经济指标,伴生有益元素银也得到了综合回收利用。A lead oxide ore in Yunnan was complicated alkali - oxidized ore of high - lead and low - zinc. The research results of the mineral processing technology showed that the effect of recovery lead oxide was better using the process of vulcanization and flotation by new combined collectors than the general xanthate collectors. Lead concentration of Pb 52.24% with a recovery of 67.51% was obtained by closed circuit test process, and the valuable accompanying element of silver was al- so recycled.
