Princeton Critical Minerals: Modernizing Global Supply Chains

Princeton Critical Minerals (PCM) is transforming legacy extraction into high-yield, data-driven operations. A spinout from Princeton University, we bridge the gap between scientific innovation and industrial-scale production to secure the minerals essential for global infrastructure.

Traditional lithium extraction is often slow and resource-intensive, with legacy evaporation ponds taking over 18 months to yield results. PCM’s integrated platform compresses these timelines from years to weeks while significantly reducing environmental impact.

Our Integrated Technology Stack

Lilypad™: Floating devices with proprietary, high-absorption coatings that convert sunlight to heat, accelerating evaporation rates by up to 2x.

SmartPond™: An AI-driven optimization platform providing real-time sensing and predictive modeling to turn pond operations into transparent, high-performance assets.

E-LiTE™: A separation technology achieving a 90% lithium recovery rate while concentrating brine by up to 75x. It is specifically engineered to handle low-concentration inputs, unlocking production from previously uneconomic sources such as geothermal brines and oilfield wastewater.

The PCM Difference

PCM provides an integrated platform that optimizes every stage of production—from accelerating evaporation in the Lithium Triangle to deploying modular units in previously uneconomic regions. We help our partners maximize recovery, mitigate operational risk, and accelerate revenue realization today.
