针对四川会东难处理氧化铜矿，研究了不同铵（胺）盐活化剂对氧化铜矿硫化浮选行为的影响规律。结果表明：乙二胺磷酸盐、硫酸铵、氯化铵、碳酸氢铵、磷酸氢二铵均对氧化铜矿硫化浮选有活化作用；用单一活化剂时最佳的是乙二胺磷酸盐，用组合活化剂时乙二胺磷酸盐和碳酸氢铵组合效果最好，且组合活化剂活化效果优于单一活化剂。当乙二胺磷酸盐和碳酸氢铵以1∶3组合使用，总用量为480 g/t时，闭路试验可获得铜精矿铜品位19．01％，回收率为83．31％的优良指标，与直接硫化浮选相比，精矿铜品位提高了4．05％，回收率提高了12．42％。

Using several ammonium ( amine) salts as activators, the sulfide flotation behaviors of refractory oxidised copper ores in Huidong have been studied .The results showed that ethylene di-amine phosphate , ammonium sulfate , ammonium chloride , ammonium bicarbonate and diammoni-um phosphate have significant activation to sulfide flotation of oxidised copper ores .When using single activator , the performance of ethylenediamine phosphates was the best , while using a com-posite one , the performance of ethylenediamine phosphate and ammonium bicarbonate combination was the best .The activation effect of composite activator was better than that of single .When ethyl-enediamine phosphate and ammonium bicarbonate were combined with ration 1∶3 and dosage 480 g/t, a final copper concentrate with grade of 19.01% and recovery of 83.31% were obtained. Compared to the direct sulfide flotation , the concentrate grade was raised by 4.05%and the recov-ery was increased by 12 .42%.
