Abstract

L'invention concerne un procédé de récupération de déchets de phosphate de fer lithié et une application. Le procédé comprend les étapes suivantes : mélange de déchets de phosphate de fer lithié avec de l'eau pour fabriquer une bouillie, l'ajout d'alcali pour ajuster un pH jusqu'à ce que la suspension soit alcaline, le chauffage pour la réaction, le filtrage et la séparation pour obtenir un résidu de filtration ; dissolution du résidu de filtration dans l'acide, filtration et séparation, prélèvement d'un filtrat, ajout d'une solution contenant un oxalate pour la réaction, vieillissement, filtration et séparation pour obtenir un gâteau de filtration et une liqueur mère de précipitation ; mise du gâteau de filtration sous la forme d'une suspension, lavage et élimination de l'eau libre pour obtenir de l'oxalate ferreux. Un premier alcali est ajouté pour ajuster le pH, puis l'acide est utilisé pour dissoudre le résidu de filtration, une séparation solide-liquide est effectuée, le résidu de filtration est éliminé, une substance contenant de l'oxalate est ajoutée au filtrat pour chauffer et précipiter pour obtenir un précipité d'oxalate ferreux. Comparé au processus de synthèse d'oxalate ferreux à partir de déchets de phosphate de fer lithié, le processus de synthèse d'oxalate de fer à partir de déchets de phosphate de fer lithié est plus facile à commander, et le taux de récupération de fer est plus élevé, et le taux de récupération de fer peut atteindre 99 %.
