It doesn't refine them. We do.
Zero organic solvents. Deployed in months. 1/10th the capex.

On the ocean floor, thermal vents sort dissolved metals naturally. PNNL scientists spent 5+ years turning that chemistry into Co-flow™: a patented process that separates critical metals into individual oxides at 99%+ purity, using only food-grade reagents.
Refining that once took a football field of tanks now fits on a 5×5 ft cart.
Precision instead of brute force. No solvent extraction, no hazardous waste, no decade-long buildout.
