Understanding Lithium Brine Deposits: Global Locations and Geology

Where Brine Deposits Are Found and Why They Matter

Lithium brine deposits are typically located in arid regions with high evaporation rates—including salt flats, underground aquifers, and deeply buried subsurface reservoirs. The world’s most notable lithium-rich brine regions are:

• Chile’s Atacama Salt Flats (Salar de Atacama): Hosts some of the most productive and vast lithium brine resources globally.
• Argentina’s Salinas Grandes and Hombre Muerto: Part of the “Lithium Triangle,” contributing significantly to global supply.
• Bolivia’s Salar de Uyuni: Holds vast reserves, potentially leading future extraction projects.
• United States’ Salton Sea (California) and Silver Peak (Nevada): Emerging as critical brine-based lithium sources in North America.

These deposits occur where saline groundwater or subsurface fluids, often mixed with other salts like sodium, potassium, and magnesium, accumulate and become enriched in lithium over geological time. The process of lithium extraction from brine deposits relies on bringing these mineral-rich fluids to the surface and isolating lithium carbonate or lithium hydroxide—key battery manufacturing compounds—through a multi-phase sequence of concentration and purification steps.

Key Geological Features of Lithium-Rich Brines

• Salt Flats (Salars): Flat plains with surface or near-surface crusts of salt—form through intense evaporation in closed basins.
• Underground Aquifers: Subsurface zones where dissolved lithium accumulates in saline water, tapped through deep wells.
• High Evaporation Rates: The arid climate of these regions increases the concentration of lithium within the brines.
• Rich in Contaminant Salts: Often mixed with magnesium, sodium, potassium, calcium, and other elements requiring separation during lithium extraction.

The economic viability and sustainable potential of these brine deposits come from their massive scale, significant concentration of lithium, and favorable surface mining conditions.

Why Brine-Based Lithium Extraction Is Key in 2025

• Accelerates the transition to renewable energy systems and electric vehicles (EVs) by providing critical battery minerals.
• Supports local agricultural economies by coexisting with farming operations—especially when using advanced, sustainable extraction methods.

Lithium Extraction from Brine Deposits: Process and 2025 Technological Advances

Traditional Extraction Method: Solar Evaporation Ponds

The traditional method of lithium extraction from brine deposits involves a sequence of steps:

1. Pumping: Brine is pumped from underground aquifers or reservoirs to the surface.
2. Solar Evaporation: The fluid is spread over large, shallow ponds—sometimes covering hundreds of hectares. Over 12 to 18 months, the evaporation process increases the concentration of lithium salts.
3. Harvesting: As saline brines evaporate, lithium compounds precipitate and can be isolated and purified.
4. Purification: Multiple chemical steps are used to remove unwanted elements like magnesium and potassium until lithium carbonate or hydroxide can be extracted.

This method is cost-effective but faces some challenges in 2025:

• Highly dependent on climatic conditions—requires lengthy, consistent sun and heat for evaporation.
• Extensive water and land use—threatens local groundwater supply and can negatively affect agriculture in arid regions.

Innovation: Direct Lithium Extraction (DLE) and Advanced Technologies

Direct lithium extraction (DLE) technologies are rapidly becoming the standard in 2025, offering a dramatic improvement in sustainability and efficiency. DLE encompasses:

• Selective Adsorption & Ion Exchange: Engineered resins or materials bind only lithium ions, leaving other salts behind.
• Advanced Filtration & Membrane Separation: High-tech filters and membranes isolate lithium compounds from brine quickly and with lower water loss.
• Electrochemical Extraction: Uses electrical currents to pull lithium ions from solution.
• Continuous Processing: Minimizes land use and eliminates massive evaporation ponds, making the process faster (days versus many months).

The benefits of DLE and similar technologies in 2025 include:

• Greatly reduced water consumption and environmental impact compared to traditional solar evaporation methods.
• Potential to recover more lithium (even from lower concentration brines) and open up new, previously unviable extraction sources.
• Shorter timelines and increased yield for battery-grade lithium, enabling faster renewable energy adoption.
• Smaller land footprint, supporting agricultural coexistence and land management.

The significance of these technological advances in the lithium extraction from brine deposits sector cannot be overstated, as they help solve water scarcity issues, reinforce agricultural resilience, and ensure an uninterrupted supply of critical battery minerals for the global green economy.

For advanced operations managers, satellite-based monitoring tools like those offered by Farmonaut provide timely, actionable data to track surface changes, water usage, and land impacts, ensuring best practice compliance in lithium extraction projects.
