西藏地区含有大量优质碳酸型盐湖锂资源，盐湖提锂技术基本突破，但由锂精矿制备电池级碳酸锂的工艺技术有待突破。本文对西藏盐湖锂精矿制备电池级碳酸锂的几种工艺进行了探讨，分析了碳化－热解法、碳化－离子交换法、岢化－碳化法、岢化－配位除杂法四种工艺的优缺点。综合比较工艺稳定性、加工成本等优势，作者认为碳化离子交换除杂工艺是相对较为稳定可靠的工艺。
西藏地區含有大量優質碳痠型鹽湖鋰資源，鹽湖提鋰技術基本突破，但由鋰精礦製備電池級碳痠鋰的工藝技術有待突破。本文對西藏鹽湖鋰精礦製備電池級碳痠鋰的幾種工藝進行瞭探討，分析瞭碳化－熱解法、碳化－離子交換法、岢化－碳化法、岢化－配位除雜法四種工藝的優缺點。綜閤比較工藝穩定性、加工成本等優勢，作者認為碳化離子交換除雜工藝是相對較為穩定可靠的工藝。

Tibet area Saline Lakes contains extremely large high-quality carbonate type lithium resources, extraction tech-nology of lithium from Saline Lake has basically been breakthrough, but the technology of preparing battery grade lithium carbonate by lithium concentrate needs breakthrough.In this paper, the several kinds preparation technologies of battery grade lithium carbonate by lithium concentrate in Tibet saline lakes were discussed, analyzed the advantages and disadvan-tages of four kinds technologies: the carbonization-pyrolysis method, carbonization-ion exchange method, causticization-carbonization method and causticization-coordinated removing impurity method.The authors synthetically compared the ad-vantages of process stability and processing cost, thinks that the carbonization-ion exchange removal impurity process is rel-atively stable and reliable process.
