The synthesis, characterization, and its response to metal ions of a novel thiourea N,N'-diethoxycarbonyl-N '',N'''-(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.
