Abstract

La présente invention appartient au domaine technique des matériaux de batterie. L'invention concerne une méthode de préparation d'un phosphate de fer de haute pureté et son utilisation. La méthode de préparation comprend les étapes suivantes : mélange et agitation d'un déchet de phosphure de fer, d'un liquide acide, d'un oxydant et d'un adsorbant, chauffage et lixiviation, et réalisation d'une séparation solide-liquide pour donner un premier filtrat et un premier résidu de filtre ; ajout d'un liquide alcalin au premier filtrat, ajustement du pH et conservation de la chaleur, et réalisation d'une séparation solide-liquide pour donner un second résidu de filtre et un second filtrat ; réalisation d'un traitement thermique sur le second résidu de filtre pour donner de l'oxyde de fer ; réalisation d'un broyage à billes à haute énergie sur l'oxyde de fer, et ajout d'un tensioactif pour activation pour donner une suspension ; et mélange de la suspension avec de l'acide phosphorique, chauffage pour réaction, réalisation d'une séparation solide-liquide, lavage d'une phase solide, puis frittage pour donner du phosphate de fer. Selon la présente invention, de l'oxyde de fer et de l'acide phosphorique sont préparés à partir des déchets de phosphure de fer et analogues en tant que matières premières. Après activation, au moyen d'une réaction à basse température, le phosphate de fer de haute pureté est préparé. Le procédé de réaction est une préparation en boucle fermée, et moins de déchets sont produits.
