Abstract

este pedido refere-se a métodos de recuperação de metais a partir de sulfetos metálicos que envolvem o contato do sulfureto metálico com uma solução de sulfato ácido contendo sulfato férrico e um reagente que possui um grupo funcional tiocarbonila, em que a concentração de reagente na solução de sulfato ácido é suficiente para aumentar a taxa de extração de íons metálicos em relação a uma solução de sulfato ácido que não contém o reagente, para produzir uma solução grávida contendo os íons metálicos.
