摘要/Abstract

摘要： 采用机械化学活化方法，在机械活化过程中用K2SO4为活化添加剂，强化锂云母中惰性Li?O配位结构活化转型，通过温和稀酸浸出高效分离锂，考察了活化过程添加剂用量、球磨时间和球料比及浸出条件如酸浓度、液固比、搅拌速度、温度和时间等对锂回收率的影响，确定了最佳工艺条件，讨论了反应过程机理。结果表明，机械化学活化强化破坏云母片层结构中的Si?O?K结构，降低了Si?O配位结构对Li?O配位结构的牵制力，导致Li?O键强减弱，反应活性增加。在最优条件下(精矿与K2SO4质量比5:1，球磨机转速500 r/min，球料质量比20:1，球磨时间3 h，硫酸浓度15vol%、液固比4 L/g、反应温度80℃、浸出搅拌速率200 r/min)，锂浸出率可达99.1%。
