Revolutionizing Lithium Refining

Introducing our patented Green+ Lithium Refining process for cleaner, more efficient, and cost-competitive lithium production.

A Smarter, Cleaner Way to Refine Lithium

Where do We Stand in the Supply Chain?

Lithium Ark’s patented process transforms lithium chloride (LiCl) into battery grade lithium hydroxide (LiOH) – efficiently, cleanly and economically. Our process eliminates traditional emissions-intensive steps while maintaining the highest quality standards and reducing overall production costs and capital expenditure.

Green+ Lithium Refining Process:

Build to Lead the Future of Lithium Refining

Innovation

Innovative chemistry

Our process replaces complex, reagentintensive refining with a simple, circular salt system.

It lies in its reciprocal salt chemistry, which uses the natural balance between lithium and potassium salts to separate and purify lithium efficiently from lithium chloride.

PERFORMANCE

Better Li recovery, lower capex and opex

Our process achieves low OPEX and CAPEX through simplicity and efficiency: fewer reaction steps, less energy use, and fully recyclable reagent result in a cleaner process that costs less to build and run.

It captures nearly all lithium – above 99% – while consistently producing battery-grade quality.

REAL IMPACT - BETTER ECONOMICS - CLEANER OPERATIONS

SCALABILITY

Ready for industrial scale

Our process has been independently validated by Kemetco, GEA and IBZ at TRL-5 level.

These independent test confirmed the process´s stability, high lithium recovery, and ability to consistently produce battery-grade material from different feedstocks; using offshelf equipment.

ECO-EFFICIENCY

Circular and environmentally friendly

Our patented circular chemistry instead of consuming reagents, it recycles potassium within the process, reducing waste, cost, and environmental impact.

The process avoids the use of soda ash, a major CO2 source in conventional refining, achieving a cleaner and more sustainable operation.

Revolutionary lithium refining process that delivers environmental and economic advantages.

Patented, Proven, and Ready to Scale

Our Green+ Lithium Refining technology is protected by patents, independently validated at TRL-5, and engineered for seamless industrial deployment. This reduces technology risk, accelerates commercialization timelines, and provides investors with confidence backed by real-world performance.

Lower CAPEX and OPEX

A simpler process design, reduced reagent needs, and lower energy inputs translate into substantially lower capital investment and operating costs. This strengthens IRR, improves payback periods, and makes projects more resilient in low-price lithium cycles.

Higher Lithium Recovery, Higher Revenue

Green+ achieves higher lithium recovery per tonne of feedstock, directly increasing production yield and revenue potential. Better recovery improves asset efficiency and enhances long-term project profitability.

Significantly lower CO₂ Emissions

Eliminating soda ash, reducing energy intensity, and enabling full circularity results in a much lower carbon footprint compared to traditional refining. When powered by renewable energy, the process can achieve near-zero operational emissions — a strong advantage for ESG-aligned investors and customers.

Reduced Energy and Water Use

Efficient crystallisation steps and a circular reagent loop dramatically reduce both energy demand and water consumption. This lowers operating costs while increasing sustainability credentials and reducing exposure to resource constraints.

Flexible Battery-Grade Output

Producers can switch between battery-grade lithium hydroxide and lithium carbonate with minimal changes to the flowsheet. This flexibility allows operations to adapt to market cycles and pricing dynamics, maximizing revenue opportunities across the value chain.

Simpler, Circular Chemistry

Green+ eliminates complex multi-stage flowsheets and reduces the need for fresh reagents. Its circular KOH/KCl loop minimizes waste and resource dependency, improving operational reliability and reducing long-term cost exposure.

No Dependence on Soda Ash

By removing soda ash entirely, the process eliminates exposure to volatile global reagent markets and geopolitical supply risks. This provides cost stability, reduces procurement risk, and strengthens long-term operational resilience.
