德兴铜矿生物浸出 溶剂萃取 电积铜生产中 ,在溶剂萃取界面产生严重的乳化现象 ,致使整个生物冶铜工艺运行状况恶化。通过对界面乳化物特性进行系统研究 ,认为乳化物的生成是由有机相中杂质和降解产物 ,以及萃取过程中的沉淀物和萃原液中固体悬浮物引起。同时 ,初步探讨了预防界面乳化物生成的措施 Dexing copper mine bioleaching solvent extraction electrowinning copper production, the solvent extraction interface to produce a serious emulsification, resulting in deterioration of the overall biological copper smelting process. By systematically studying the characteristics of the interfacial emulsions, it is considered that the formation of emulsions is caused by the impurities and degradation products in the organic phase, as well as the precipitates in the extraction process and the solid suspensions in the extract. At the same time, preliminary measures to prevent the formation of interfacial emulsions
