Abstract

L'invention concerne un procédé de traitement de courants de déchets contenant du fer. Le procédé comprend la division du courant de déchet en un premier et un second courant, puis l'ajout d'un agent neutralisant (p. ex. de l'hydroxyde de calcium) au premier courant pour former une pâte partiellement neutralisée, et le mélange de ce premier courant partiellement neutralisé avec le second courant pour former un courant mélangé. Le courant mélangé comprend des précipités de chlorure ferreux et d'hydroxyde métallique, qui sont séparés.
