<p>In the recovery of metal, such as a non-ferrous metal, from an aqueous solution thereof by extracting the metal into an organic solvent phase, back extracting the metal into an aqueous phase therefor, and plating out the metal electrolytically, the back extraction and plating out are both carried out in the cathode compartment of an electrochemical cell, e.g. in a rotating cathode contactor. This procedure reduces the number of process operations, improves process effectiveness and gives the metal in a form (e.g. powder) suitable for subsequent removal and processing.</p> |
