Abstract
L'invention se rapporte à un procédé permettant de récupérer l'oxyde de zinc provenant de déchets industriels de composants divers, y compris le zinc, le plomb, le fer et le cadmium, en calcinant les déchets à une température élevée, en les traitant avec une solution de chlorure d'ammonium maintenue à une température élevée, en séparant les composants non dissous de la solution, en traitant la solution avec du métal de zinc pour déloger les ions métalliques non désirés de la solution, en refroidissant la solution afin de précipiter les composés de zinc, en lavant les composés de zinc précipités pour retirer les composés non désirés tels que le dichlorure de diamino-zinc, et en séchant le composé de zinc restant qui est de l'oxyde de zinc essentiellement hydraté; l'on obtient de l'oxyde de zinc essentiellement pur.
