摘　　要：为了解苯甲羟肟酸+丁基黄药高效捕收氧化铜矿石的情况,在孔雀石单矿物浮选试验基础上进行了实际矿石浮选试验。结果表明,苯甲羟肟酸的双配位基可与铜离子形成稳定的五元环的羟肟酸铜螯合物,对氧化铜矿物尤其是孔雀石具有良好的捕收能力和选择性;苯甲羟肟酸与丁基黄药在最佳配合比3.5的情况下产生的协同捕收作用最强,孔雀石回收率最高。In order to find the floating performance of copper oxide ore by synergy of benzohydrox-amic acid and butyl xanthate,the natural ore flotation experiment was carried out based on the single malachite mineral flotation tests.Results indicated that：five unite ring benzohydroxamic copper chelate can be obtained through double dentate in benzohydroxamic acid reaction with copper ions.The chelate has good performance in collecting copper oxide,typically malachite.The chelate has the highest synergy collection performance with ratio of benzohydroxamic acid to butyl xanthate is 3.5,and malachite recov-ery rate is the highest.
