Hydrometallurgical processing of mo1ybdenite becomes more and more popular these years because of its environmentally friendly,and it is more attractive especially for low-grade and complex ores [1].Much research has been done and many processes such as oxygen pressure,sodium hypochlorite leaching,electric-oxdiation have been developed [2].In the electric-oxidation process,Mo (Ⅵ) and Re (Ⅶ) existing in the molybdenite were leached into the solution [3],and extraction process was adopted to extract Mo(Ⅵ) and Re(Ⅶ) firom the solution in this paper.
