ABSTRACT:
Valuable metals in manganese nodules have their solvent solubilities altered by forming an alkaline-manganese electric cell using manganese nodules as a cathode active material component and discharging the cell with a selected discharge load. Thus, the solvent extraction percentage for Mn in manganese nodules can be controlled to less than 60% and that for other valuable metals be elevated to at least 80% by selecting the discharge load properly.
