Sobre IBD

Derzeit werden etwa 80 % der weltweiten Chalkopyritkonzentrate pyrometallurgisch verarbeitet (Rösten, Schmelzen und Raffinieren). Bei diesem Verfahren entstehen Staub und Emissionen von Schwefeldioxid (SO2) und Kohlendioxid (CO2) in die Umwelt, was zu Problemen bei der Kontrolle und Verarbeitung zur Herstellung von Schwefelsäure führt. Ein weiterer Nachteil der pyrometallurgischen Verfahren besteht darin, dass sie hohe Investitionen und eine Kapazität von über 100.000 t/Jahr Kupfer erfordern. In der vorliegenden Studie wird die Entwicklung eines neuen Verfahrens für die Direktlaugung von Chalkopyritkonzentraten auf der Grundlage thermodynamischer und metallurgischer Grundlagen vorgeschlagen. Das Hauptziel ist die Erzeugung von marktfähigen Produkten und umweltverträglichen Rückständen.

    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.
