| Abstract | ||
| The leaching characteristics of sea nodules of Indian Ocean were investigated by leaching of Cu, Ni, Co, and Zn using 0.5 M of the solvent D2EHPA in ammonia solution, and 10% Isodecanol in Kerosene. It was found that Zn recovery almost remained steady after the first contact, i.e (0.017 g/L) while the recovery of Cu, Ni and Co increased even after third contact and reached its maximum value i.e (0.82 Cu , 0.90 Ni , 0.296 Co ). Also the result had revealed that the best time of mixing aqueous solution of metals ions to be recovered was found to be 2min, while the recovery of metals ions decreases as the organic to aqueous ratio was increased from 1:1 to 4:1. | ||
