Abstract

Procédé de déchloruration et d'oxydation de sous-produits servant de matière de départ pour l'obtention de zinc et constitués de cendres de zinc, oxydes de zinc ou autres. La matière de départ contenant du chlore est introduite dans un réacteur (1) et chauffée à 750 degrés C au moyen d'un gaz chaud (4) alimentant le réacteur, de façon à évaporer le chlorure de zinc, après quoi le chlorure de zinc gazeux est soutiré à travers une sortie (6) au sommet (7) du réacteur, et un produit formé de zinc et d'oxyde de zinc déchlorurés est soutiré du réacteur (1) à un niveau (5) inférieur.Process for dechlorination and oxidation of by-products used as starting material for obtaining zinc and consisting of zinc ash, zinc oxides or others. The starting material containing chlorine is introduced into a reactor (1) and heated to 750 degrees C by means of a hot gas (4) feeding the reactor, so as to evaporate the zinc chloride, after which the zinc chloride gas is withdrawn through an outlet (6) at the top (7) of the reactor, and a product formed of dechlorinated zinc and zinc oxide is withdrawn from the reactor (1) at a lower level (5).
