Abstract
L'invention concerne un procédé pyrométallurgique en une seule étape pour la récupération de métaux non ferreux à partir de résidus contenant du zinc, en particulier à partir de sous-produits de l'industrie de production du zinc et du plomb, tels que la goethite et la jarosite. L'invention concerne un procédé destiné à récupérer des métaux à partir de résidus industriels de Zn, contenant Zn, Fe et S, dans lequel Zn est distillé, Fe est scorifié et S est oxydé en SO2, caractérisé en ce que l'on effectue la distillation de Zn, la scorification de Fe et l'oxydation de S dans un procédé en une seule étape, en faisant fondre les résidus dans un four comprenant au moins un chalumeau à plasma immergé générant un mélange de gaz oxydant, et en introduisant un réducteur solide à la coulée. Le procédé permet d'obtenir une oxydation de S et une scorification de Fe, tout en obtenant simultanément une réduction et une distillation de métaux tels que Zn.
