Lithium Production Processes
The process can be voltage-controlled to minimize Na and Mg ions participating in the Li removal process. When the electrode in A is full, a new or recycled Fe III PO 4 is replaced and the process continues. As a result, Li will be continuously removed from the brine (A) and Li will be gradually concentrated in the pure electrolyte (B).
