Sobre IBD

Atualmente, cerca de 80% dos concentrados de calcopirite do mundo são processados por via pirometalúrgica (ustulação, fundição e refinação). Esta metodologia gera poeiras e emissões de dióxido de enxofre (SO2) e dióxido de carbono (CO2) para o ambiente, causando problemas no seu controlo e no processamento para a produção de ácido sulfúrico. Além disso, outra desvantagem dos processos pirometalúrgicos é que requerem um alto investimento e uma capacidade superior a 100.000 t/ano de cobre. O presente estudo propõe o desenvolvimento de um novo processo para a lixiviação direta de concentrados de calcopirite com base em fundamentos termodinâmicos e metalúrgicos. O objetivo principal é a geração de produtos comercializáveis e de resíduos ambientalmente estáveis.

    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.
