⚠️ Seawater Rare Earth Extraction
Commercial Viability: NOT ECONOMICALLY VIABLE Concentration: Parts per trillion (10⁻¹² range) - extremely low Chemical Form: REE³⁺ ions and carbonate complexes Status: No commercial extraction of rare earth elements from seawater exists anywhere globally. The extremely low concentrations (million times lower than aluminum) and complex separation requirements make extraction uneconomical compared to conventional ore processing. Research Status: Academic studies focus on REE behavior in seawater for geochemical tracing, not commercial extraction.

Bastnäsite Processing Route
Roasting: 500-700°C to oxidize Ce³⁺ to Ce⁴⁺ HCl Leaching: Selective dissolution of trivalent REEs Solvent Extraction: 50-200 stages for individual separation Advantages: Lower thorium content, established process Recovery: 85-95% for light REEs
Monazite Processing Route
Alkali Decomposition: 140°C with 73% NaOH Thorium Removal: Precipitation as hydroxide Acid Conversion: REE hydroxides to chlorides Challenges: Radioactive waste management Recovery: 80-90% for REEs
