| titleOfInvention |
Process for the extraction and separation of nickel and / or cobalt. |
| abstract |
The present invention also aims to provide a separation of nickel from cobalt by charging them, selectively, in an organic phase compatible with one or more of one of the preceding objects. The present invention therefore relates to a hydrometallurgical process intended for the recovery of metals in which is obtained, more particularly, an aqueous filler solution originating from an acid leaching and containing nickel and / or cobalt ions. The pH of the solution is maintained in a range between approximately 2 and 6. The aqueous loading solution is brought into contact with an organic phase, immiscible in water, which contains an extraction solvent in order to charge it with ions. nickel and / or cobalt metals so as to obtain an organic phase containing metals. |
