Abstract

Procédé d'oxydation des ions ferreux en solution, et plus particulièrement procédé de lixiviation amélioré des métaux communs et/ou d'uranium dans des minerais, des concentrés ou des résidus en utilisant des ions ferriques comme agent d'oxydation. Une cuve de réacteur (10) renferme une solutions contenant des ions ferreux, par exemple une pulpe ou un concentré de sulfure de cuivre. Un agitateur (12) peut être installé pour activer la lixiviation des métaux communs en solution. Une partie de la solution contenant des ions ferreux est retirée de la cuve du réacteur (10) et pompée à travers un mélangeur en continu (14) pour faciliter l'oxydation du sulfate ferreux en sulfate ferrique. La solution contenant des ions ferreux est ensuite renvoyée vers la cuve du réacteur (10) où les ions ferriques servent à dissoudre le sulfure de cuivre en sulfate de cuivre soluble. Les procédures d'oxydation ferreuse et de lixiviation des métaux peuvent être exécutées soit simultanément soit successivement pour permettre la récupération de cuivre, d'autre métaux communs ou d'uranium dans les minerais, les concentrés ou les résidus.
