In July 2019, the first phase project producing 5,000 tons/year battery grade Lithium carbonate was put into operation. At the same time, in order to solve the contradiction between the dispersion of brine resources and the centralized construction of factories, the “Aircraft Carrier Type” lithium extraction mode has been proposed, and a mobile lithium extraction device based on high-performance adsorbent has been developed. Combined with fixed workshop precision processing, the lithium extraction capacity has been further improved.
