PROCESS FOR EXTRACTING METAL VALUES FROM MANGANESE NODULES

Sodium ions are added to manganese nodules to convert the montmorillonite clay naturally occurring in the nodule material into a bonding agent for pelletization into spherical agglomerates. The addition of coking coal to provide bonding strength after reduction, during which the clay bond is destroy...
