METHOD FOR RECOVERING VALUABLE METALS FROM LITHIUM BATTERY BLACK MASS

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.
