摘　　要：简述了助熔剂氧化锂在保护渣中的作用,针对保护渣造渣原料碳酸锂资源少、价格高的现状,阐述了采用沉淀法从废旧钴酸锂电池中回收锂的研究现状及方法,并指出沉淀法回收废钴酸锂电池的有价金属,可直接得到碳酸锂产品,收得率高、对环境污染小、工艺简单、成本较低,适宜工业化规模生产碳酸锂;且锂电池回收碳酸锂成本远低于矿物制取碳酸锂。利用钴酸锂电池回收碳酸锂生产保护渣,可降低生产成本、节约能源消耗,减少保护渣使用过程中对环境的污染,具有显著的经济、社会效益。The role of lithium in the mold slag was summarized. Aimed at the status quo that lithium carbonate was scarce resource but with high price, the precipitation recovering methods of spent lithium-ion batteries and the related work were elaborated. It＇s found out that the precipitation can obtain directly lithium carbonate used as raw material for slag, with high yield, small environmental pollution, the simple process and low cost, which is suitable for industrial scale production of lithium carbonate. The cost of recycling lithium carbonate is much lower than the cost of extracting lithium carbonate from mineral. The application of lithium carbonate from spent lithium-ion batteries in mold slag production can reduce costs, save energy, reduce environmental pollution, and have significant economic and social benefits.
