摘要
采用除镁后卤水母液蒸发浓缩提锂进行碳酸锂制备工艺研究。实验结果表明:通过控制母液浓缩倍数为300倍,反应温度90℃,反应时间40min,沉锂剂滴加速度20~25mL/min等工艺条件,锂的收率可达83%以上,平行实验结果说明所探讨的工艺条件重现性好。
The preparation of lithium carbonate was carried by adopting mother liquor evaporation of removal magnesiumb fine . The experimental results showed that lithium yield could reach over 83% by controlling concentration multiple of 300 times,reaction temperature for 90 ℃ , reaction time for 40min, dripping speed for 20 - 25 mL/min.
