⚠️ Seawater Boron Extraction
Commercial Viability: NOT ECONOMICALLY VIABLE Concentration: 4.5 ppm (as boric acid) Chemical Form: B(OH)₃ (boric acid) and B(OH)₄⁻ (borate ion) Status: While seawater contains measurable boron (4.5 ppm), no commercial extraction exists. The concentration is too low compared to rich mineral deposits, making extraction uneconomical. Note: Some experimental ion exchange methods have been tested but remain far from commercial viability. Land-based borate minerals remain the only practical source.
