Abstract

Procédé perfectionné pour le grillage des matières constituées par des sulfures. La présente invention décrit un procédé pour le grillage des matières constituées par du sulfure de zinc et du sulfure de plomb comprenant la formation de boulettes essentiellement sphériques composées surtout de sulfure de plomb et l'enrobage de ces boulettes avec une matière constituée surtout de sulfure de zinc, puis le grillage des boulettes enrobées dans un appareil de grillage pour effectuer l'oxydation du sulfure surtout en oxyde. Utilisation de ce procédé pour griller les sulfures sans les fritter au préalable.
