The present application relates to the technical field of lithium batteries and discloses a method for recovering valuable metals from lithium battery black mass. Lithium battery black mass is mixed with a sulfur-containing substance and an inhibitor, followed by roasting, water leaching, and filtering to obtain a first filtrate and a first filter residue; a lithium salt is prepared from the first filtrate, and other valuable metals are recovered from the first filter residue; wherein the inhibitor is at least one selected from the group consisting of magnesium oxide, magnesium hydroxide, calcium oxide, calcium hydroxide, aluminum oxide, and aluminum hydroxide. The method provided by the present application enables the recovery of valuable metals from various types of lithium battery black mass, ensuring a high lithium recovery rate (≥98%) while allowing more other valuable metals to remain in the residue phase (with a loss rate <2%) for subsequent recovery, thereby improving the recovery rates of the other valuable metals.
