Green Lithium Extraction Under Scrutiny
Mining companies are promoting new technologies for direct lithium extraction, aiming to reduce environmental impacts in South America's "lithium triangle".
However, experts warn that this technology may not be ready for large-scale deployment, citing concerns over water use and depletion of scarce freshwater resources.
- Lithium is found in salty brine beneath the region's salt flats.
- The "lithium triangle" spans Argentina, Bolivia, and Chile, holding over half of the world's known lithium reserves.
More research is needed to assess the environmental impacts of direct lithium extraction.
