Lithium Extraction from Water: Mining Brines, Geothermal, and Seawater
Traditional Brine Extraction
Lithium mining has historically relied heavily on extracting lithium-rich brines from salt flats. Nowhere is this more prominent than in the so-called “Lithium Triangle” of South America—encompassing Chile, Argentina, and Bolivia. These salt flats hold the largest global reserve concentrations and have traditionally underpinned global lithium production.
- Brines are pumped to the surface, evaporated over months to years, and processed for lithium carbonate or lithium hydroxide.
- However, this process is water- and land-intensive, creates brine waste, and can degrade fragile desert ecosystems.
- With worsening drought and aquifer depletion, the environmental costs are mounting.
Emerging Frontiers: Geothermal Brines and Seawater
-
Geothermal Brine Extraction
- Geothermal power plants worldwide—especially in California, USA and Iceland—produce hot brines as a by-product.
- Selective lithium recovery from these brines allows operators to couple clean energy production with lithium extraction, effectively tapping a new category of sustainable reserves with far less incremental environmental impact.
- Direct lithium extraction (DLE) methods—using ion-exchange and advanced membranes—are scaling up rapidly by 2026.
-
Seawater Extraction
- Seawater holds vast but dilute lithium concentrations (0.17 ppm).
- Innovations in special absorbents and electrochemical processes are rapidly improving the efficiency and feasibility of extracting lithium from ocean water, although cost and technical barriers remain high.
- By 2025-2026, research breakthroughs in selective ion-sieves, nanotechnology membranes, and scalable pilot plants are bringing the dream of seawater lithium extraction closer to commercial reality.

Previously dismissed due to processing challenges, these clays are increasingly attractive for diversification in regions such as North America where brine and hard rock reserves are limited.
Technological Advances in Clay Extraction
-
Hydrometallurgical Processing:
- Innovations in selective leaching agents (often using a mix of sulfuric acid and other specialty reagents) have increased recovery rates and economic viability of these reserves.
-
Acid Leaching and Thermal Processing:
- Modern methods optimize temperature and reagent concentration to extract lithium from otherwise intractable clays with minimal environmental and chemical footprint.
-
Pilot Programs and Commercialization:
- By 2025, several companies in the USA and elsewhere are investing in pilot projects and scaling up, opening new, water-efficient sources of lithium to help meet global demand.
Notably, extracting lithium from clay is less reliant on large water footprints versus brine and hard rock mining. However, the need for sustainable reagent management and waste treatment remains a technical and regulatory hurdle.
The emergence of AI-powered satellite monitoring in mining, as provided by our Fleet Management Platform, adds decision-making efficiency and traceability for companies pioneering new clay extraction methods.
