Abstract

La pratique industrielle de conversion de matte de cuivre comprend l'oxydation du sulfure de fer et l'oxydation ultérieure du sulfure de cuivre avec formation de cuivre blister, et est effectuée dans des convertisseurs Peirce-Smith ou Hoboken en mode discontinu. La présente invention résout ladite difficulté en permettant à ce procédé industriel d'être effectué en continu. Le procédé de l'invention consiste à utiliser un flux gravitationnel continu de matte de cuivre dans deux réacteurs connectés en série par un canal, dans lesquels l'oxydation et la scorification du fer de la matte de cuivre sont effectuées dans le premier réacteur puis l'oxydation du sulfure de cuivre et la formation de blister sont effectuées dans le deuxième réacteur. L'opération intensive de conversion de matte de cuivre liquide ou liquide et solide est effectuée en continu au moyen de lits fixes pour augmenter le taux d'oxydation, dans chaque réacteur, avec des temps de fonctionnement réduits.
