⚠️ Seawater Rhenium Extraction

Commercial Viability: NOT ECONOMICALLY VIABLE Concentration: 0.0001 ppm (4 ng/L) - among the lowest of all elements Chemical Form: ReO₄⁻ (perrhenate ion) Status: No commercial concentrated seawater rhenium form exists. The extremely low concentration (100,000 times less than uranium) makes extraction completely uneconomical. Note: Even experimental ion-exchange methods have proven impractical due to the ultra-trace concentrations.
