Often called “white oil,” lithium has become a critical element in today’s clean-energy ecosystem. With its low atomic mass, high specific heat capacity, and exceptional electrochemical potential, lithium is uniquely suited for advanced battery chemistries—including high-energy-density lithium-ion systems and next-generation solid-state technologies
InfraCorp is helping meet this demand by deploying cutting-edge extraction, processing, and refining technologies across its integrated lithium operations.
Key advancements include:
- Proprietary process optimization for greater efficiency
- Enhanced brine concentration methodologies that improve yield
- High-throughput refining systems that deliver consistent battery-grade purity
- Significant reductions in water use, energy intensity, and overall environmental impact

InfraAds™ Four Pillars
1. SELECTIVE ADSORPTION
Proprietary iBeads™ with engineered molecular structures selectively capture lithium ions while rejecting impurities like magnesium and calcium.
[Li⁺, Mg²⁺, Ca²⁺, Na⁺ in brine] + [iBead-H⁺] → [iBead-Li⁺] + [Mg²⁺, Ca²⁺, Na⁺, H⁺]
Bead Technology Highlights:
- Material: Hybrid organic-inorganic matrix
- Selectivity: >200:1 Li/Mg ratio
Capacity: 8-12 mg Li/g
2. EFFICIENT ELUTION
Dilute hydrochloric acid (2-3%) releases concentrated lithium chloride solution from the beads.
[iBead-Li⁺] + [H⁺ from HCl] → [iBead-H⁺] + [LiCl solution]
Process Efficiency:
- Elution Time: 2 hours
- Acid Consumption: 0.5 kg HCl per kg Li produced
- Li Concentration: 25,000-40,000 mg/L in eluate (50-80× concentration)
3. ADVANCED PURIFICATION
Multi-stage purification removes residual impurities to achieve battery-grade specifications.
Purification Steps:
-
- Oxidation: Remove iron and manganese
- Precipitation: Remove magnesium and calcium at pH 10.5-11.0
- Polishing: Ion exchange for boron removal
- Filtration: Final polishing to 1 μm
4. PRODUCT CONVERSION & BRINE RE-INJECTION
Final Product Options:
- Lithium Carbonate (Li₂CO₃): React with sodium carbonate
- Lithium Hydroxide (LiOH): Electrolysis of LiCl solution
Water Stewardship:
- 95% brine re-injection to source aquifer
- Closed-loop water management
- Freshwater consumption: 20-30 m³/t Li (vs. 50-70 m³/t for ponds)
