  "textContent": "Provided is a method for stabilizing the degree of oxidation of molten battery waste, and definitively separating slag and alloy. The method is provided with a pre-oxidation step (ST20) for roasting and oxidizing battery waste; and a drying step (S20) for melting the battery waste oxidized in the pre-oxidation step, and separating and recovering the slag and the valuable metal alloy. By providing the pre-oxidation step (ST20) for oxidizing the battery waste by roasting in advance of the drying step (S20), it is possible to stably obtain the optimal degree of oxidization in a melting step (ST21), and to improve the slag-alloy separation efficiency.",
