In addition to salt, salt lake is also rich in precious resources such as potassium, sodium, magnesium, lithium and boron. The technology of extracting lithium from salt lake brine is to extract potassium salt from salt lake brine to form lithium-containing brine, and lithium carbonate can be obtained after removing impurities.

China's lithium resources rank fourth in the global market, but 82% of them are distributed in salt lakes, 90% of which are brine resources, mainly concentrated in Qinghai and Tibet. Zhabuye Salt Lake in Tibet (owned by Tibet Mining) is the first salt lake in China and the third largest salt lake in the world. It is a natural carbonate lake with abundant lithium resources. The proven lithium reserves of this salt lake are about 6.5438+0.84 million tons. However, long production cycle, many impurities, high technical requirements and harsh development environment have always been the biggest obstacles to extracting lithium from salt lakes. However, with the development of time and research, some technical breakthroughs have been made in lithium extraction technology from salt lakes. At present, with the rising tide of new energy vehicles, lithium resources are rising, which deserves serious study.
