Efforts to Green Lithium Extraction Face Scrutiny
Direct lithium extraction has been touted as a method to reduce mining impacts in South America.
Mining companies are promoting new technologies to extract more lithium from the region's salt flats with lower environmental impacts.
Experts warn it may not be ready for large-scale deployment
The "lithium triangle" spanning Argentina, Bolivia, and Chile holds over half of the world's known lithium reserves.
- Lithium is found in salty brine beneath the region's salt flats.
- The region is among the driest places on Earth.
Scientists warn that the technology could worsen freshwater depletion in the region and say more research is needed.
