摘　　要：氧化铅锌矿是我国重要的矿产资源,由于其具有矿物成分复杂、含泥量大、嵌布粒度细等特点,导致分选困难。在介绍氧化铅锌矿表面特性的基础上,阐述了脂肪酸类捕收剂、螯合类捕收剂、两性捕收剂等直接浮选氧化铅锌矿的作用机理及应用,以及硫化—黄药、硫化—胺盐、硫化—黄药—胺盐等硫化浮选氧化铅锌矿的作用机理及应用。最后,指出加强捕收剂作用机理研究,探索捕收剂改性、复配技术,开发高选择性的新型及组合捕收剂是氧化铅锌矿浮选的研究重点。Lead-zinc oxide ore is an important mineral resource in China,and its separation is difficult.Because of its complex mineral composition,large mud content,and fine dissemination size.Base on summarizing the surface characteristics of lead-zinc oxide ore,the mechanism and application of direct flotation of lead-zinc oxide ore such as fatty acid collector,chelating collector and amphoteric collector were summarized,as well as the mechanism and application of sulfide flotation of lead-zinc oxide ore such as sulfide-xanthate,sulfide-amine salt and sulfide-xanthate-amine salt.Finally,it was pointed out that strengthening the research on the mechanism of collectors,exploring the modification and compounding technology of collectors,and developing novel and combined collectors with high selectivity are the research focus of flotation of lead-zinc oxide ore.
