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).
Today, there are two main ways to pull lithium from the ground. Until recently, most lithium mining occurred in Chile, where lithium is extracted from brines: salty liquid found at the Earth's surface or underground. To extract lithium, that liquid is pumped from the earth and then placed in pools where the water can evaporate, leaving behind ...
