摘要(Abstract)：

为开发西藏硫酸钠亚型盐湖—扎北盐湖中的卤水锂资源,提出盐湖联合开发—碳酸盐型卤水与扎北富锂卤水兑卤提锂的新方法。实验以扎北高锂卤水(BI)为原料,扎布耶盐田富碳酸根卤水(BII)为天然沉淀剂,在不同温度(5~90℃)及兑卤比(V_(BII)/V_(BI)=0.5~2.5)条件下进行了碳酸锂混盐的兑卤沉淀。结果表明,在V_(BII)/V_(BI)=1.75、90℃条件下进行兑卤沉淀时,锂收率82.66%,碳酸锂含量88.25%。用该法所制的碳酸锂混盐利于后续提纯,经调浆水洗、烘干研磨后可获纯度高、分散性好的碳酸锂粉末。

关键词(KeyWords)： 扎北盐湖;硫酸钠型卤水;兑卤法;碳酸锂
