摘　　要：针对反萃后的电富液通常会夹带有机相,如不妥善处理的情况,会在电积过程中影响阴极板质量的情况,分析了电富液除油机理,以及常见的电富液净化除油技术。以刚果(金)某铜钴湿法矿山企业电富液除油技术实践为例,着重研究了超声波-气浮除油装置和聚结式净化除油。该企业将原有除油系统升级为1台处理量为450 m^(3)/h的超声波-气浮除油装置与1台处理量为180 m^(3)/h的聚结式除油装置。升级后的实践表明,两种除油方式都具有较好的除油效果。In response to the fact that the strong electrolyte after back extraction usually contains organic phases,which will affect the quality of the cathode plate during the electrowinning process if it is not properly handled.This paper analyzes the mechanism of strong electrolyte oil removal and common strong electrolyte purification and oil removal technology.Taking the practice of strong electrolyte oil removal technology for a copper-cobalt hydrometallurgical mine operation in DRC as an example,the paper focuses on the research of ultrasonic-air flotation oil removal unit and agglomerated purification and oil removal technology.The enterprise has upgraded its original oil removal system to one ultrasonic-air flotation oil removal unit with a processing capacity of 450 m^(3)/h and one agglomerated oil removal unit with a processing capacity of 180 m^(3)/h.After the upgrading,the practice shows that both oil removal methods have good oil removal effect.
