Sobre IBD

Actuellement, environ 80 % des concentrés de chalcopyrite du monde sont traités par des moyens pyrométallurgiques (grillage, fusion et raffinage). Cette méthode génère des poussières et des émissions de dioxyde de soufre (SO2) et de dioxyde de carbone (CO2) dans l’environnement, ce qui pose des problèmes de contrôle et de traitement pour produire de l’acide sulfurique. En outre, un autre inconvénient des procédés pyrométallurgiques est qu’ils nécessitent un investissement élevé et une capacité de plus de 100 000 t/an de cuivre. La présente étude propose le développement d’un nouveau procédé de lixiviation directe des concentrés de chalcopyrite sur des bases thermodynamiques et métallurgiques. L’objectif principal est de générer des produits commercialisables et des résidus écologiquement stables.
