摘要:
碱性锌锰电池是用量最大的原电池。废旧碱性锌锰电池被丢弃后，会对环境产生污染，其回收利用已越来越受到人们的重视。在实验室研究了水浸—煅烧—真空铝热还原处理废旧碱性锌锰电池的工艺，通过物相与元素含量分析，对处理后物料的物相存在形式及钾和锌的回收率进行了研究。研究结果表明，废旧碱性锌锰电池物料通过水浸可使99%的氢氧化钾回收；水浸渣经煅烧后得到的煅后渣主要物相为ZnO和ZnMn2O4；煅后渣经真空铝热还原，可将锌和锰还原，并可使98%的锌回收，还原渣的主要物相为氧化铝与铝锰合金。
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.
