Abstract
(EN) A process for recovering Cobalt ion, Nickel ion and Manganese ion from metal-containing residues The present invention relates to a process for recovering one or more metal ions selected from the group consisting of Cobalt, Nickel, Manganese and a mixture thereof from metal-containing residues comprising: A) leaching the residue with a leaching solution comprising lactic acid to obtain a filtrate 1 and a solid cake 1; B) separating the filtrate 1; C) precipitating the Cobalt lactate, Nickel lactate or Manganese lactate from the filtrate 1 to obtain a filtrate 2 and a precipitate 1; and D) separating the precipitate 1; or alternatively, A) leaching the residue with the leaching solution to obtain a filtrate 1 and a solid cake 1; E) precipitating the Cobalt lactate, Nickel lactate or Manganese lactate from the filtrate 1 to obtain a filtrate 3 and a solid cake 2; and F) separating the solid cake 2; and G) separating the Cobalt lactate, Nickel lactate or Manganese lactate from the solid cake 2.
(FR) La présente invention concerne un procédé de récupération d'un ou de plusieurs ions métalliques choisis dans le groupe constitué par le cobalt, le nickel, le manganèse et un mélange de ceux-ci à partir de résidus contenant du métal comprenant les étapes consistant à : A) lixivier le résidu avec une solution de lixiviation comprenant de l'acide lactique pour obtenir un filtrat 1 et un gâteau solide 1 ; B) séparer le filtrat 1 ; C) précipiter le lactate de cobalt, le lactate de nickel ou le lactate de manganèse à partir du filtrat 1 pour obtenir un filtrat 2 et un précipité 1 ; et D) séparer le précipité 1 ; ou, en variante, A) lixivier le résidu avec la solution de lixiviation pour obtenir un filtrat 1 et un gâteau solide 1 ; E) précipiter le lactate de cobalt, le lactate de nickel ou le lactate de manganèse à partir du filtrat 1 pour obtenir un filtrat 3 et un gâteau solide 2 ; et F) séparer le gâteau solide 2 ; et G) séparer le lactate de cobalt, le lactate de nickel ou le lactate de manganèse du gâteau solide 2.
