  • Oxalic acid leaching of marine nodules
    Patent number: 4259295
    Abstract: Metal values of ferromanganese nodules harvested from ocean floors are placed in aqueous solution suitable for partition as by selective extraction with chelating agents by treating the nodules with aqueous solutions which contain oxalic acid or mixture of oxalic acid with a strong acid. These unique reagents may be used alone or in combination with other reducing, complexing or acidic treating agents.
