Abstract
Un método para deprimir sulfuros de cobre y sulfuros de hierro en un proceso de recuperación de flotación de molibdenita utiliza polisulfuros alcalinos o alcalinotérreos a un pH concentrado elevado. El método de enriquecer el contenido de molibdenita de una suspensión 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 más polisulfuros alcalinos, polisulfuros alcalinotérreos o una mezcla de los mismos, a la suspensión, en donde el pH de la suspensión es mayor a aproximadamente 8,0; y pasar un gas a través de la suspensión a fin de separar el material mediante flotación selectiva, recuperando la molibdenita de una espuma. El método puede incluir los pasos de proporcionar una suspensión 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 alcalinotérreos, o una mezcla de los mismos, por Kg de suspensión (base seca), en donde el pH de la suspensión resultante es mayor a aproximadamente 8; y pasar un a gas a través de la suspensión a fin de separar el material mediante flotación selectiva, recuperando la molibdenita de una espuma.
