Abstract
This method for recovering a valuable metal from a used LIB includes: a step of adding, to an electrode assembly taken out of a detoxified used LIB, metallic zinc in an excess amount relative to a mass of the electrode assembly; a step of heating a mixture of the electrode assembly and the metallic zinc to form a molten metal; a step of taking out the molten metal and separating the molten metal into an alloy metal and a slag; and a step of heating the alloy metal to volatilize zinc in the alloy metal, and thereby, recovering an alloy metal of a valuable metal.
