Discover how Lilac Solutions’ direct lithium extraction (DLE) ion-exchange technology is transforming lithium production. Faster, cleaner, and eco-friendly lithium for electric vehicles and energy storage.

Lilac Solutions: Revolutionizing Lithium Extraction with Ion-Exchange Technology
The demand for lithium—critical for electric vehicles (EVs) and large-scale energy storage—is skyrocketing. Traditional lithium extraction methods, especially from brines, are slow, water-intensive, and environmentally taxing. Lilac Solutions is changing the game with direct lithium extraction (DLE) using ion-exchange (IX) technology.
This innovative approach promises faster lithium recovery, higher purity, and a lower environmental footprint, making it a key player in the global green energy transition.
What Is Lilac Solutions’ Ion-Exchange Technology?
Lilac Solutions’ DLE system uses proprietary ion-exchange beads to selectively capture lithium ions from brine while leaving other salts behind. The process can be broken down into simple steps:
- Brine Feed – Brine from lithium-rich sources flows through IX modules.
- Lithium Capture – Lithium ions bind to the IX beads.
- Regeneration / Elution – Lithium is released into a concentrated solution using a safe regeneration process.
- Purification & Conversion – The lithium-rich eluate is processed into battery-grade lithium carbonate or hydroxide.
- Reinjection – Remaining brine is returned to the source, reducing water usage and environmental impact.
Key Advantages of Lilac’s Ion-Exchange Lithium Extraction
- High Recovery Rates – Up to 98% lithium recovery, depending on brine composition.
- Durable Media – IX beads last thousands of cycles, ensuring cost efficiency.
- Low Water Consumption – Uses up to 10x less freshwater than conventional methods.
- Purity & Selectivity – Produces high-quality lithium with minimal impurities.
- Modular & Scalable – Systems can be deployed at pilot, demo, or commercial scale.
- Faster Extraction – Lithium extraction that traditionally took months via evaporation now occurs in days.
Real-World Success Stories
Kachi Project (Argentina)
