Abstract
La présente invention concerne un procédé de prétraitement d'un concentré d'oxydes métalliques pauvre en composés soufrés, comprenant les étapes consistant à : utiliser un concentré d'oxydes métalliques pauvre en composés soufrés ayant une teneur en composés soufrés inférieure à 10 % p/p ; (a) chauffer le concentré d'oxydes métalliques pauvre en composés soufrés à une température élevée et en présence d'oxygène et d'une source combustible externe pour oxyder en oxydes correspondants les composés soufrés contenus dans le concentré pauvre en composés soufrés et/ou pour décomposer thermiquement lesdits composés soufrés afin d'obtenir un concentré d'oxydes appauvri en composés soufrés et un rejet gazeux contenant des composés soufrés ; (b) séparer le résidu de calcination des oxydes métalliques appauvri en composés soufrés du rejet gazeux contenant des composés soufrés ; (c) refroidir le résidu de calcination des oxydes appauvri en composés soufrés obtenu ; (d) refroidir le rejet gazeux par trempe ; et (e) épurer le rejet gazeux refroidi de sorte à récupérer les composés soufrés.
