A composite oxide produced from used dry battery was used to decrease Mg content in Al-Mg alloy at high temperature. The oxide was found to consist of ZnMn2O4, ZnMnO3, and ZnO by XRD analysis. After a reaction between a pellet made from the oxide powder and the alloy in liquid at 973 K for 2 h, Mg content in the alloy decreased from 4.0 to 3.6 mass%. During the reaction, metallic Mg probably diffused into the pellet to form MgMn2O4 and then exchanged with Zn(II) in ZnMn2O4.
