Abstract[English]
The invention is in the field of pyrometallurgy and describes a process for the recovery of lithium by fuming. The process comprises smelting Li-ion batteries or their waste in a furnace with slag formers, resulting in a molten bath with distinct alloy and slag phases, and flue dust. Notably, at least 30% of the lithium is transferred to the flue dust under the chosen conditions without adding alkali or earth alkali halides. Li can then be recovered from the flue dust, valuable metals, such as Co and/or Ni, can be recovered from the alloy, and the remaining slag can be used in new smelting or Li- fuming operations.[French]
L'invention se rapporte au domaine de la pyrométallurgie et décrit un procédé de récupération de lithium par volatilisation. Le procédé comprend la fusion de batteries Li-ion ou de leurs déchets dans un four avec des agents formateurs de laitier, ce qui permet d'obtenir un bain de fusion avec des phases d'alliage et de laitier distinctes, et des cendres volantes. En particulier, au moins 30 % du lithium est transféré dans les cendres volantes dans les conditions choisies sans ajout d'halogénures de métal alcalin ou alcalino-terreux. Li peut ensuite être récupéré à partir des cendres volantes, des métaux de valeur, tels que Co et/ou Ni, peuvent être récupérés à partir de l'alliage, et le laitier restant peut être utilisé dans de nouvelles opérations de fusion ou de volatilisation de Li.
