Project Overview
The world's first seawater lithium extraction plant construction project marks a new stage of seawater lithium extraction from engineering verification to industrialization. Lishi has conducted a one-year validation of seawater lithium extraction engineering for the concentrated brine discharged from Qingdao Baifa seawater desalination plant. The seawater throughput reached 200000 tons, and a highly selective and high-throughput lithium extraction material that can be applied in seawater has been polished. It has finalized an industrial device suitable for large-scale seawater lithium extraction. More than 700 sets of experimental data indicate that the product meets the quality requirements of downstream customers and fully meets environmental standards. At the same time, Lishi also conducted experiments on extracting lithium from raw seawater with extremely low lithium content, and its adsorption efficiency fully met the industrial requirements of the design.
