Abstract
L'invention concerne un procédé de réutilisation de résidus solides contenant du fer ou des métaux lourds avec addition éventuelle de minerai de fer. Ledit procédé consiste à introduire, à faire tourbillonner, et à amorcer les résidus avec des réducteurs contenant du carbone, et de l'oxygène dans un cyclone de fusion (6), à fondre lesdits résidus, à réduire et à évaporer des métaux lourds volatils, à réduire des oxydes de fer, à transporter les gaz et la fonte du cyclone de fusion (6) vers un contenant de séparation (7) couplé directement, dans lequel se déroule une séparation de la fonte et des gaz, à séparer les métaux lourds évaporés des gaz à l'extérieur du contenant de séparation (7), et à transporter la fonte dans un contenant métallurgique (10) séparé du contenant de séparation (6). Selon ledit procédé, on additionne d'une part des réducteurs dans le contenant métallurgique (10), on réduit en fer les oxydes de fer de la fonte avec formation d'une scorie pauvre en fer, et on applique d'autre part une énergie électrique destinée à couvrir au moins partiellement les pertes de chaleur et l'énergie de réduction, de manière à transformer les résidus contenant du fer et des métaux lourds en produits réutilisables à 100 %.
