Abstract

L'invention concerne des variantes, de chaînes industrielles de production de trichlorure de fer à partir de résidus de combustion de pyrite, lesquelles comprennent : un dispositif de recuit, un dispositif de chloration, un dispositif de sublimation et un dispositif de désublimation. Selon une première variante, le dispositif de recuit consiste en un four à lit fluidisé, le dispositif de chloration consiste en un four rotatif à tambour ayant une température de chauffage pouvant atteindre 250°C et dans lequel on utilise en qualité d'agent de chloration du chlorure d'ammonium solide, le dispositif de sublimation consiste en un four rotatif à tambour ayant une température de chauffage pouvant atteindre 350°C. Selon une seconde variante, le dispositif de recuit, le dispositif de chloration et le dispositif de sublimation consistent en des fours à lit fluidisé. Le résultat technique consiste en une simplification du processus de transformation des résidus de combustion de pyrite avec conversion de la majeure partie du fer en trichlorure de fer.
