Abstract
La présente invention concerne un procédé de traitement d'un résidu de lixiviation généré dans une lixiviation d'un concentré de métal contenant du soufre. Le résidu de lixiviation est introduit dans un réacteur, un gaz de fluidisation étant injecté dans le réacteur pour former un lit fluidisé contenant au moins une partie du résidu de lixiviation. Ainsi, le résidu de lixiviation est chauffé en présence de particules inertes à une température comprise entre 600 et 900 °C dans une atmosphère oxydante pour produire des particules calcinées et SO2. Au moins 60 % en poids des particules inertes est retiré du lit fluidisé, tandis qu'au moins 60 % en poids des particules calcinées est retiré conjointement avec un flux gazeux contenant des dégagements gazeux et le gaz de fluidisation.
