%X 以玉龙高铁铜精矿常压酸浸液为研究对象&#65292;通过萃取剂遴选及萃取性能对比试验&#65292;选择Mextral5640H作为最优萃取剂&#65292;通过两级逆流萃取&#65292;当有机相浓度为20%&#65292;萃取相比(O/A)为1.7:1时&#65292;铜铁分离系数达到2500&#65292;萃余液中铜离子浓度降至0.4 g/L&#65292;经过一级反萃可使富铜液中的铜离子浓度达到45 g/L&#65292;实现了玉龙高铁铜精矿常压酸浸液中铜的选择性高效提取。<br>Taking the atmospheric acid leaching solution of Yulong high-iron copper concentrate as the research object, Mextral5640H was selected as the optimal extractant through the comparison test of extractant selection and extraction performance. Through two-stage countercurrent extraction, when the organic phase concentration was 20% and the extraction ratio (O/A) was 1.7:1, the copper-iron separation coefficient reached 2500, and the copper ion concentration in the raffinate was reduced to 0.4 g/L. After one-stage stripping, the copper ion concentration in the copper-rich liquid can reach 45 g/L. The selective and efficient extraction of copper from the atmospheric acid leaching solution of Yulong high-iron copper concentrate was realized.
