Abstract

L'invention concerne un procédé de traitement de l'arsenic contenu dans des produits intermédiaires de fusion non ferreux, en particulier un procédé de traitement de l'arsenic sous sa forme de sulfure, lequel satisfait aux normes de lixiviation (conformément à la notice n° 13 de l'agence pour l'environnement), est excellent en termes de performances de filtration et de formation facile de scorodite stable avec une reproductibilité élevée sans aucune opération lourde. Ledit procédé de production de scorodite comprend : une étape de lixiviation consistant à lixivier l'arsenic dans une région faiblement acide à partir d'un produit intermédiaire de fusion non ferreux contenant de l'arsenic ; une étape d'ajustement du liquide consistant à ajouter un agent oxydant au lixiviat de façon à oxyder l'arsenic trivalent en arsenic pentavalent ; et une étape de cristallisation consistant à convertir l'arsenic du liquide ajusté résultant en cristaux de scorodite.
