Abstract

La présente invention concerne un procédé de régénération cyclique de déchets de phosphate de fer et une application correspondante. Le procédé consiste à : mélanger et dissoudre des déchets de phosphate de fer et une liqueur acide pour obtenir une solution de fer-phosphore ; prélever une petite partie de la solution de fer-phosphore pour préparer un précipitant de phosphate de fer ; puis ajouter le précipitant de phosphate de fer dans la solution de fer-phosphore restante pour une réaction afin d'obtenir un précipité de phosphate de fer dihydraté ; utiliser une partie du précipité de phosphate de fer dihydraté en tant que précipitant pour la réaction dans le lot suivant ; et préparer le reste du précipité de phosphate de fer dihydraté en phosphate de fer anhydre. Selon la présente invention, le précipitant de phosphate de fer est préparé pour être utilisé pour la préparation subséquente de phosphate de fer, le phosphate de fer à chaque fois préparé peut être utilisé pour la préparation suivante du phosphate de fer et le procédé est un procédé de préparation simple, n'a besoin de liqueur alcaline que dans un étage de préparation du précipitant, n'utilise pas de liqueur alcaline lors de la production subséquente, est plus respectueux de l'environnement, présente une uniformité de produit élevée, un faible coût, une productivité élevée, une faible consommation d'énergie et est approprié pour une production industrielle à grande échelle.
