Abstract
Un metodo para deprimir sulfuros de cobre y sulfuros de hierro en un proceso de recuperacion de flotacion de molibdenita utiliza polisulfuros alcalinos o alcalinoterreos a un pH concentrado elevado. El metodo de enriquecer el contenido de molibdenita de una suspension que tiene molibdenita y al menos uno de sulfuros de hierro y sulfuros de cobre puede incluir los pasos de agregar una cantidad efectiva de un reactivo depresor seleccionado de uno o mas polisulfuros alcalinos, polisulfuros alcalinoterreos o una mezcla de los mismos, a la suspension, en donde el pH de la suspension es mayor a aproximadamente 8,0; y pasar un gas a traves de la suspension a fin de separar el material mediante flotacion selectiva, recuperando la molibdenita de una espuma. El metodo puede incluir los pasos de proporcionar una suspension que comprende molibdenita y uno o mas de sulfuro de cobre y sulfuro de hierro; agregar un reactivo depresor, en donde el reactivo depresor comprende al menos aproximadamente 0,003 Kg de polisulfuros alcalinos, polisulfuros alcalinoterreos, o una mezcla de los mismos, por Kg de suspension (base seca), en donde el pH de la suspension resultante es mayor a aproximadamente 8; y pasar un gas a traves de la suspension a fin de separar el material mediante flotacion selectiva, recuperando la molibdenita de una espuma
