In this study, research was conducted to develop a technology for recovery of zinc and manganese oxide powder through a high temperature pyrometallurgical recycling process from black powder of alkaline and Zn-C batteries. In order to remove chlorides such as potassium chloride present in the black powder, the black powder was washed using deionized water, and the washed black powder was used as a material for recovering zinc and manganese. Pre-thermodynamic calculations were performed using a FactSage program to set the process temperature. Zinc oxide present in the black powder reacted with residual carbon and was reduced to zinc gas, and zinc powder could be obtained by rapidly condensing the generated zinc gas. In addition, it was confirmed that only the manganese oxide phase was present in the black powder residue in the crucible.
