Abstract

Un sistema de separación de cobre/molibdeno que utiliza agua de mar en el circuito de desbaste y agua desalinizada en el circuito de limpieza. Tanto en el circuito de desbaste como en el de limpieza, se utilizan medios diseñados hidrófobos para recuperar las partículas minerales de interés. El circuito de limpieza incluye una etapa de carga de molibdeno configurada para contactar la pulpa acondicionada con los medios diseñados en una cámara de reacción agitada, y cargar la molibdenita hidrófoba en los medios diseñados.
