Abstract
Adsorptive bubble techniques, using in-situ generated hydrous manganese oxide, and organic precipitating reagents, are employed to separate cobalt, copper,· nickel, and manganese from the leach liquors of sulfated deep-sea ferromanganese nodules. Recoveries of the four metal values are studied as a function of pH for each system. Two organic precipitating reagents are examined: salicylaldoxime (on an exploratory scale), and sodium diethyldithiocarbamate (NaDEDC).
