Abstract

The present disclosure belongs to the technical field of lithium battery recycling, and discloses a method for separating and recovering valuable metals from waste ternary lithium batteries. The method includes the following steps: adding a persulfate to a waste ternary lithium battery powder, and conducting oxidative acid leaching to obtain a leaching liquor and a leaching residue; adding an alkali to the leaching liquor to allow a precipitation reaction; adding a sulfide salt to allow a reaction; adjusting a pH to allow a precipitation reaction to obtain a nickel hydroxide precipitate and a liquid phase A; adding a carbonate to the liquid phase A to allow a reaction, and conducting solid-liquid separation (SLS) to obtain lithium carbonate; and subjecting the leaching residue to calcination, adding a chlorate, heating a resulting mixture, and conducting SLS to obtain manganese dioxide.
