摘要:
每年我国产生的废弃锂离子电池数量持续增加，实现废弃锂离子电池中贵重金属资源的回收和再利用具有很大的价值。本研究用葡萄糖作为还原剂来促进钴酸锂的酸浸过程，研究了葡萄糖投加量、酸浓度、固液比、浸出温度、浸出时间、pH 等因素对钴的浸出率的影响。实验结果表明：这几个因素对钴的回收率影响都较为明显，最佳实验条件如下:浸出温度为 90℃，浸出时间为 1 h，硫酸浓度为 3 mol/L，液固比为 250 mL/g，葡萄糖添加量为 10 g。在此实验条件下钴的平均浸出率为 98.68 %。表明利用硫酸-葡萄糖体系进行酸浸效果显著，降低了反应成本。
Abstract:
Every year, the number of waste lithium-ion batteries in China continues to increase, so it is of great value to realize therecovery and reuse of precious metal resources in waste lithium-ion batteries. In this study, glucose was used to facilitate the picklingprocess of lithium cobalt oxide as a reducing agent. The effects of glucose dosage, acid concentration, solid-liquid ratio, leachingtemperature, leaching time, pH and other factors on the leaching rate of cobalt were studied. The experimental results show that thesefactors have obvious effects on the recovery of cobalt. The best experimental conditions are as follows: the leaching temperature is 90℃,thenleaching time is 1h, the sulfuric acid concentration is 3 mol/L, the solid-liquid ratio is 250 mL/g, and the glucose dosage is 10g,respectively. Under the experimental conditions, the average leaching rate of cobalt is 98.68%. The results show that the sulfuric acidglucose system has a significant effect on acid leaching and the reaction cost is reduced.
