The underlying ion-exchange technology acts as a “filter” for lithium ions. By circulating the lithium-rich fluid through the Li-Capt® filters, lithium ions are captured in the active material specially designed by GeoLith, and the rest of the brine is returned, unaltered, to the original reservoir.
This process has been proven thanks to three pilot plants that GeoLith has designed in Europe and South America.
Li-Capt® is a modular and scalable technology, adaptable to any kind of brine, and any kind of extraction project.

The process is totally sustainable, with zero CO2 emissions, zero waste, and full respect of the aquifers.
