Abstract

Procédé et installation pour dessaler les laitiers de refusion. Ce procédé est caractérisé en ce qu'on soumet le sel d'un laitier préalablement concassé à une lixiviation avec de l'eau dans le dispositif de dissolution,-on sépare les fractions métalliques des composants non métalliques comprenant un mélange d'oxydes d'aluminium en fonction de la densité et on épaissit ces derniers avec la saumure, après quoi on soumet une partie de ladite saumure à un processus d'épaississement dans une installation de cristallisation sous vide, tandis qu'on dirige l'autre partie vers un second dispositif de dissolution. Concerne d'une manière générale, la sidérurgie et plus particulièrement la récupération des sels et des fractions métalliques présents dans les laitiers métalliques.
