Abstract

Procédé perfectionné pour purifier des sels ou boues salines contenant des impuretés organiques. On fond les sels à une température d'environ 600 à 1 000 degrés C et on traite la masse fondue par un gaz contenant de l'oxygène. L'opération peut être effectuée dans un four à plusieurs chambres alimente en gaz contenant de l'oxygène et équipé de dispositifs de chauffage et des conduits nécessaires. Le procédé selon l'invention dégage moins de gaz résiduaires et de poussières que les procédés thermiques de la technique antérieure.
