⚠️ Seawater Manganese Extraction

Commercial Viability: NOT ECONOMICALLY VIABLE Concentration: 0.0001 ppm (0.1 ppb) - extremely low Chemical Form: Mn²⁺ ion (persists due to slow oxidation kinetics) Status: No commercial concentrated seawater manganese form exists anywhere globally. The extremely low concentration (1,000 times lower than aluminum) makes extraction uneconomical compared to ore mining. Note: While manganese nodules exist on the ocean floor containing 15-30% Mn, deep-sea mining faces significant technical, environmental, and economic challenges.
