摘　　要：The synthesis,characterization,and its response to metal ions of a novel thiourea N,N＇-diethoxycarbonyl-A＂,iV″＇-（1,2- ethylidene） dithiourea was reported.The results show that this dithiourea with new structure can react with Cu^（2＋） and Ni^（2＋） separately,and has a best selectivity to Fe^（3＋） ions.Bench-scale flotation tests were also carried out,verifying it has higher copper flotation recovery and better selectivity to sulfide ores containing Cu compared with universal collectors.The synthesis,characterization,and its response to metal ions of a novel thiourea N,N＇-diethoxycarbonyl-A＂,iV″＇-（1,2- ethylidene） dithiourea was reported.The results show that this dithiourea with new structure can react with Cu^（2＋） and Ni^（2＋） separately,and has a best selectivity to Fe^（3＋） ions.Bench-scale flotation tests were also carried out,verifying it has higher copper flotation recovery and better selectivity to sulfide ores containing Cu compared with universal collectors.
