Notes:
Deep-sea manganese nodules must be potentially valuable one of the most mineral resources containing several economically valuable metal elements. Manganese minerals in the nodules are regarded principally as todorokite and δ-MnO2. The todorokite phase is porous and enriched in copper and nickel, while the porous δ-MnO2 phase is enriched in cobalt. Porosity and adsorption as well as dissolution characteristics have been observed for each constituent mineral. Furthermore the pore diffusion coefficient has been calculated. Moreover, the zeta potential of each constituent mineral has been measured in order to evaluate the electrochemical property. This has been applied successfully to the selective concentration of copper and nickel bearing or cobalt bearing minerals in deep-sea manganese nodules.
