The project was founded in 2007, covering an area of more than 50 acres, with a lithium salt production line with an annual output of 5,000 tons, mainly producing lithium hydroxide and lithium carbonate. In order to improve product quality, Guocheng led a comprehensive upgrade of the factory buildings and production lines. At present, Guocheng has completed the land acquisition and will complete the first phase of technical transformation in June 2023. The annual production capacity of lithium salts can reach 5,000 tons; the second phase of technical transformation will be completed in December of the same year, and the annual production capacity of lithium salts can reach 10,000 tons.
