Aquatech Unveils PEARL™: A Full Flow Sheet Technology Platform for Lithium Extraction, Refining, and Purification

CANONSBURG, Pa., June 24, 2025 /PRNewswire/ -- Aquatech has announced the launch of PEARL™, a comprehensive technology platform enabling optimized full flow sheet process development and at-scale delivery for the extraction, refining, and purification of lithium.

PEARL™ (Purification, Extraction and Refining of Lithium) enables the production of battery-grade lithium from a diverse range of feedstock, including hard rock, clay, and continental, geothermal, or oilfield brines.

Reflecting Aquatech's commitment to full life-cycle partnerships with lithium resource owners, the PEARL™ technology platform encompasses:

• End-to-end integration, including process development, full-scale execution and facilities O&M
• Full process wrap backed by performance guarantees
• Customized, fit-for-resource process technology to deliver desired project outcomes

The PEARL™ platform enables a fit-for-resource approach, which ensures that each process solution is optimized to the unique mineralogy of any resource. This approach is supported by Aquatech's industry-leading applied development, testing and validation capabilities, and by decades of experience delivering complex process solutions that underpin hundreds of billions of dollars of capital projects delivery.

"PEARL™ is the enabling solution for critical minerals, addressing the industry's core pain points: fragmented solutions, technical and schedule risk, and long project development cycles," said Venkee Sharma, Executive Chairman at Aquatech. "With PEARL™, we deliver an optimized full flow sheet technology solution that is tailored to specific lithium resources, tested and validated in-house, and backed by full-scale delivery with performance guarantees. The result is lower CAPEX and OPEX, higher recovery, and accelerated time to market."

The PEARL™ platform spans three core process technology groups:

• Adsorbent-based lithium extraction
• Eluate/post-leach purification and concentration
• Lithium chemical conversion and refining

Aquatech's lithium process technology solutions power the world's foremost lithium projects, from Rio Tinto's salar brine operation at Hombre Muerto in Argentina to Lithium Americas' Thacker Pass project in Nevada, USA, the largest known lithium resource in North America.
