Metodo para lixiviar molibdeno y/o renio que comprende exponer el mineral a una solucion acuosa a base de cloro, en que la suma de hipoclorito y acido hipocloroso es al menos 10%mol de la especie oxidante, permitir la oxidacion del molibdeno y recuperar el metal de la solucion de lixiviacion cargada.

摘要

A method for leaching molybdenum and/or rhenium from a sulfide ore and/or concentrate containing such, the method comprising the steps of: Exposing the ore and/or concentrate to an aqueous solution of chlorine-based oxidizing species in which the sum of the concentrations of hypochlorite and hypochlorous acid is at least 10 mol % of the chlorine-based oxidizing species; Allowing and/or facilitating the oxidation of the molybdenum and/or rhenium by the hypochlorite and/or hypochlorous acid, thereby decreasing the pH such that the predominant chlorine-based oxidizing species becomes chlorine; Allowing and/or facilitating the oxidation of the molybdenum and/or rhenium by the chlorine thereby producing a pregnant leach solution; and Passing the pregnant leach solution to a means for metal recovery.
