Zusammenfassung:Ni, Cu, Co and Mo are extracted from a complex mineral contg Mn, Fe, Ni, Cu, Co, and Mo by (a) reducing the complex mineral with a synthesis gas CO/CO2 or CO/H 300-800 degrees C (b) leaching the reduced complex mineral with an aqs. soln. of an ammonium salt and ammonia, (c) separating a leaching soln. which is essentially free of dissolved Fe and Mn, from the residue, and (d) recovering Ni, Cu, Co and Mo from the leaching soln. Process is used to recover these metals from manganese nodules and similar complex minerals found on the sea bed, simply, directly and economically.
