Abstract

In ammonia leaching cobalt extraction generally does not exceed 50%, whereas copper and nickel recoveries in excess of 85% are achieved. Since manganese nodules possess high specific surface areas, the poor cobalt recovery may be related to the presence of finely divided leach residues. Adsorption experiments have been conducted to investigate the of pH. The manganese-rich phase has a stronger affinity for dissolved metal than does the iron-rich phase. Nickel interacts only weakly with the leach residues; however, both copper and cobalt are strongly adsorbed.
