摘要: 羟肟酸钠与丁黄药联用,可以提高矽卡岩氧化铜矿的浮选效率,降低药剂消耗.特别是羟肟酸-黄药“混合剂”的合理使用,促成了氧化铜矿浮选技术的新进展:处理含孔雀石和假孔雀石矿石,能获得精矿品位约26%Cu,回收率近80%,从高硅泥质铜矿中,可直接浮出精矿含铜≥25%.自由氧化铜回收率≥85%,选择合适的调整剂及相应的流程结构更有利于羟肟酸-黄药“混合剂”在Cu-Fe共生难选养化矿浮选中发挥最佳效用,不仅可以得到品位达36%的优质铜精矿.而且能预先浮出富含Ag的金精矿(每吨含Ag为340g,Au为108g),并有助于从铜扫选尾矿中回收铁.
Abstract:The mixed reagent of hydroxamate and xanthate,instead of xanthate alone,has been developed in treating copper oxidized ores of skarn type with reducedconsumption and increased copper recovery.The newer progress in copper oxidizedores flotation has been made by the reasonable usage of the mixed reagent.Testresults indicate that under the synergistic action of combined regulator,the copperconcentrate of 26%Cu grade can be produced from the ore containing malachiteand pseudomalachite with 80% recovery.When this hydroxamate-xanthate collectorsystem used to float another highly siliceous pelitic copper oxide ore,a copperconcentrate of 25% Cu can be obtained with recovery of 85% for free copper oxide.The proposed flowsheet is most useful to the efficiency of hydroxamate-xanthatein flotation of a siliceous Cu-Fe intergrowth oxidized ore containing Au and Ag.With this process not only a high quality copper oxidized concentrate of 36%Cucan be produced,but also a Ag-rich Au concentrate containing 340 g/t Ag and108 g/t Au can be floated selectively.And it benefits the recovery of Fe concen-trate from copper railings.
