摘要
我国盐湖锂资源主要分布于青藏高原的盐湖中,卤水类型主要为碳酸盐型和硫酸盐型。介绍了我国盐湖锂资源的概况以及国内盐湖卤水的提取技术和工业化情况,重点探讨了沉淀法、溶剂萃取法、离子交换吸附法、选择性半透膜法等,另外还探讨了我国青海柴达木盆地和西藏扎布耶盐湖锂矿资源工业化发展中存在的问题,提出在发展我国盐湖锂产业的同时,应将资源优势与绿色经济相结合,使未来的我国锂盐工业成为新型矿物提取产业的典范。
Salt lake lithium resources of China mainly exist in Qinghai-Tibet plateau, their hydrochemical types include carbonate type and sulfate type. The present paper highlights the general situation of salt lake lithium resources and their extraction technology and industrialized status in China ,with emphasis on the methods for extraction,such as the precipitation method,extraction method, ion exchange and absorption method , and selective membrane method. In addition, the problems in development of the lithium mineral resources of Qaidam Basin of Qinghai Province and the Zhabuye salt lake of Tibet are discussed. It is proposed that resource dominance should be combined with green economy during the development of lithium production from salt lake brine,to make the industry of our lithium mineral extraction become the model of mineral extraction industry of new pattern.
