Abstract
Un proceso para recuperar un primer mineral que comprende las etapas de: (a) proporcionar una pulpa que comprende sólidos y agua, en donde los sólidos comprenden el primer mineral; (b) añadir un primer depresor a la pulpa; (c) someter la pulpa a un proceso de flotación por espuma para producir una espuma que comprende el primer mineral; y (d) recuperar la espuma; caracterizado porque el primer mineral es un mineral de sulfuro, y el primer depresor consiste en uno o más ácidos ditiocarbámicos o sales de estos de fórmula (I). Una composición que comprende el primer depresor y que comprende además uno, dos o tres de un colector, un segundo depresor y un mineral. El uso de un ácido ditiocarbámico o sal de este de fórmula (I). El ácido ditiocarbámico o sal de este de fórmula (I) que es ácido 3-amino-1,2-propanodiol ditiocarbámico o una sal de este, ácido 2-amino-2-metil-1,3,-propanodiol ditiocarbámico o una sal de este, o ácido Nfeniletilendiamino ditiocarbámico o una sal de este.
