| description | The invention refers to a method for purifying a leach solution of a material, such as a battery material, wherein the method comprises providing a leach mixture by contacting the material with an acidic aqueous solution, filtering off the leach mixture through a filter means comprising a surface-active adsorbant with hydroxyl groups, to obtain a residue and as a supernatant a purified leach solution in the form of an aqueous solution comprising metal ions. The invention also relates to processes for separating various metals and metal compounds from a material such as, for example, a battery material, and processes for recycling lithium ion battery materials.
L'invention concerne un procédé de purification d'une solution de lixiviation d'un matériau, tel qu'un matériau de batterie, le procédé comprenant la fourniture d'un mélange de lixiviation par mise en contact du matériau avec une solution aqueuse acide, la filtration du mélange de lixiviation à travers un moyen de filtration comprenant un adsorbant tensioactif avec des groupes hydroxyle, pour obtenir un résidu et, en tant que surnageant, une solution de lixiviation purifiée sous la forme d'une solution aqueuse comprenant des ions métalliques. L'invention concerne également des processus de séparation de divers métaux et composés métalliques à partir d'un matériau tel que, par exemple, un matériau de batterie, et des processus de recyclage de matériaux de batterie au lithium-ion. |
