Title
(EN) SOLVENT EXTRACTION PROCESS FOR RECOVERING NICKEL AND COBALT FROM LEACH SOLUTIONS
(FR) PROCEDE D'EXTRACTION DE SOLVANT DESTINE A EXTRAIRE LE NICKEL ET LE COBALT DE SOLUTIONS DE LIXIVIATION
Abstract
(EN)
A method of separating nickel, cobalt or both from other cations contained in a leach solution, the method including the steps of subjecting the leach solution to separate solvent extraction steps using an organophosphoric acid, a carboxylic acid and an organophosphinic acid.
(FR)
L'invention concerne un procédé destiné à séparer le nickel, le cobalt ou les deux d'autres cations contenus dans une solution de lixiviation. Ce procédé comprend les opérations de soumission de la solution de lixiviation à la séparation des opérations d'extraction de solvant au moyen d'un acide organophosphoré, d'un acide carboxylique et d'un acide organophosphinique.
