摘要： A method for recovering valuable metals is provided in which the degree of oxidation of molten waste batteries is stabilized and separation between slag and an alloy is ensured. The method includes a roasting step (ST10) in which waste batteries are roasted beforehand at a low temperature of 300° C. or higher but lower than 600° C., an oxidation step (ST20) in which the waste batteries are oxidized by roasting at 1,100-1,200° C., and dry step (S20) in which the waste batteries that were oxidized in the oxidation step are melted, and slag and an alloy of valuable metals are separated from each other and recovered. By conducting the roasting step (ST10), organic carbon, which impairs the stability of the oxidation step (ST20) and which is contained, in plastic components, etc., is removed in advance prior to the oxidation step (ST20), and the efficiency of slag/alloy separation can be improved.
