摘　　要：针对广西某铅锑锌多金属硫化矿石进行了弱磁选—铅锑优先浮选工艺研究。闭路试验结果表明,采用该工艺对该铅锑锌多金属硫化矿石进行选别,在原矿含Pb 2.27%、Sb 1.98%、Zn 13.43%情况下,获得了含Pb 27.61%、Sb 23.76%、Zn 5.47%的铅锑精矿,铅回收率89.09%,锑回收率88.78%。与丁铵黑药药剂制度指标相比,铅锑精矿的铅锑品位分别提高了2.1和0.95个百分点,Pb和Sb回收率分别提高了2.76和3.65个百分点,锌回收率降低了1.57个百分点。与现场药剂制度指标相比,铅锑精矿铅锑品位分别提高了1.56和0.45个百分点,Pb和Sb回收率分别提高了2.85和2.61个百分点,锌回收率降低了1.14个百分点。Through the combination of weak magnetic separation and lead-antimony flotation in a lead-antimony-zinc polymetallic sulfide mine in Guangxi,excellent flotation indexes were obtained.To deal with the complex lead-antimony-zinc sulfide ore containing Pb 2.28%,Sb 1.98%,Zn 13.43%,closed-circuit tests indicated that was conducted,lead grade and recovery were 27.61%and 89.09%,respectively,and antimony grade and recovery were 23.76%and 88.78%,respectively,in lead-antimony concentrate with 5.47%zinc.Compared with the flotation indexes with ammonium dibutyl dithiophosphate,the grade of lead(Pb)and antimony(Sb)have increased by 2.10%and 0.95%respectively,while the recovery of Pb and Sb have increased by 2.76%and 3.65%respectively,zinc recovery rate reduced by 1.57%.Compared with the flotation indexes on-site process,the grade of lead(Pb)and antimony(Sb)have increased by 1.56%and 0.45%respectively,while the recovery of Pb and Sb have increased by 2.85%and 2.61%respectively,zinc recovery rate reduced by 1.14%.
