高硅料液萃铜过程中界面污物的影响及生产实践

扫码查看
萃铜是湿法炼铜的关键环节,萃取料液硅含量高,但是液-液界面会生成稳定的乳化液,即界面污物.界面污物是由有机相、水相和固相渣组成的多相非均质体系,一般呈絮凝油泥状.因此,有必要分析高硅料液界面污物生成机理,提出高硅料液萃取生产的控制措施,明确高硅料液严重界面乳化的处理方法,从而有效控制界面污物的影响,确保萃取作业正常进行.
Influence of Interface Contaminants during Copper Extraction Process with High Silicon Material Solution and Its Production Practice
Copper extraction is a crucial step in wet copper smelting,with high silicon content in the extraction solution,however,stable emulsions,namely interface contaminants,are generated at the liquid-liquid interface.Interface contaminant is a multiphase heterogeneous system composed of organic phase,aqueous phase,and solid phase residue,generally in the form of flocculent oil sludge.Therefore,it is necessary to analyze the mechanism of interface contaminants formation in high silicon material solution,propose control measures for high silicon material solution extraction production,clarify the treatment methods for severe interface emulsification in high silicon material solution,so as to effectively control the impact of interface contaminants and ensure the normal operation of extraction.
