Disclosed is a method for treating reverse extract liquid. This method utilizes the difference of the standard electrode potentials of various metals. Firstly, copper is recovered through cyclone electrolysis. At the same time, the chlorine gas generated by the electrolysis can remove TOC and avoid contaminating subsequent extractants. Then, zinc is separated using zinc precipitation reagents, and finally, manganese and calcium are separated using saponified Cyanex272 extractant to obtain manganese sulfate. The method of the present application is capable of graded recovery of valuable metals such as manganese, copper, zinc and the like. The purity of the recovered manganese sulfate reaches battery-grade. Compared to recovering copper in the form of copper sulfide, the sponge copper obtained in the present application has a purity greater than 98%, which has better application prospects and economic benefits. Moreover, by selectively abandoning sodium, calcium, and aluminum with low recovery value, the operation process can be simplified, unnecessary auxiliary material input can be reduced, and higher economic value can be achieved; at the same time, the method of the present application does not generate solid waste and has good environmental performance.
