Abstract: Alkaline zinc-manganese battery is the most used disposable battery, and it will pollute the environment after it is discarded. More and more attention of the recycling process of the spent zinc-manganese battery has been attracted with the increase of the battery usage. A recovery and utilization process of spent zinc-manganese battery was studied in the laboratory. The existent form of processed materials and the recovery ratio of potassium and zinc were studied. The results showed that more than 99% of potassium hydroxide could be recovered when the spent alkaline zinc-manganese battery materials was leached by water. The main phases of calcined slag were ZnO and ZnMn₂O₄. After calcined slag was processed by vacuum aluminothermic reduction, zinc and manganese could be reduced, and more than 98% of zinc could be recovered. The main phases of reduction slag were alumina and aluminum manganese alloy.
