Lithium Brine Extraction: The Supply Chain Behind the EV Revolution
Lithium brine extraction accounts for roughly half of global lithium production, with the Lithium Triangle—Chile, Argentina, and Bolivia—holding nearly 60% of the world's known brine resources. As EV battery demand accelerates, the landscape of lithium brine producers is shifting from traditional solar evaporation toward Direct Lithium Extraction (DLE) technologies that promise 90%+ recovery rates and dramatically shorter processing times.
Production Landscape
Global lithium production reached 240,000 metric tons in 2024, up from 204,000 MT the prior year. Chile's Salar de Atacama remains the single largest brine operation, with SQM alone producing over 200,000 tonnes of lithium carbonate equivalent. Argentina has emerged as the fastest-growing producer, with over a dozen new brine projects advancing toward commercial production.
| Region | Key Salars | Active Producers | Dominant Method |
|---|---|---|---|
| Chile | Atacama | SQM, Albemarle | Evaporation |
| Argentina | Hombre Muerto, Olaroz, Centenario, Llullaillaco | Rio Tinto Lithium, Allkem, Eramet, Ganfeng | Evaporation + DLE |
| Bolivia | Uyuni, Coipasa | YLB (state-owned) | DLE Pilot |
| USA | Clayton Valley, Salton Sea | Albemarle, Berkshire Hathaway Energy | Evaporation + DLE |
| China | Zabuye, Qarhan | Tibetan Summit, CITIC Guoan | Evaporation |
The DLE Disruption
Direct Lithium Extraction is reshaping the competitive landscape. Unlike evaporation ponds that require 12–18 months and vast land areas, DLE processes lithium in days to weeks with up to 50% higher efficiency. Key milestones in 2024–2025:
- Eramet Centenario (Argentina)
- First European company to achieve industrial-scale DLE production—24,000 tpa capacity with 90% lithium recovery rate, powered by a 120 MW off-grid solar farm.
- Ganfeng Mariana (Argentina)
- $790M investment producing 20,000 tpa lithium chloride from the Llullaillaco salt flat, fully operational since February 2025.
- Lilac Solutions (USA)
- Developed ion-exchange bead technology with 2,000+ cycle durability, partnering with Lake Resources for their Kachi project in Argentina.
Key Considerations for Buyers
Procurement decisions in lithium brine hinge on several factors beyond price: brine chemistry (magnesium-to-lithium ratios vary from 1:1 to 19:1, directly impacting processing costs), water rights and environmental compliance, and geopolitical stability of operating jurisdictions. Battery-grade lithium carbonate (99.5%+ purity) commands a premium, and not all brine operations meet this threshold without further refining.
