ABSTRACT:
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 stength after reduction, during which the clay bond is destroyed, is also disclosed.
