Abstract

Se refiere a un metodo para recuperar zinc de una solucion de zinc acuosa amoniacal de carbonato de amonio, en donde el metodo comprende las etapas de: poner en contacto la solucion de zinc acuosa amoniacal de carbonato de amonio con una solucion organica de un extractante de zinc, de modo que una parte del zinc se transfiera de la solucion de zinc acuosa amoniacal de carbonato de amonio , lo que produce una solucion reducida en zinc acuosa amoniacal de carbonato de amonio y una solucion organica enriquecida en zinc de un extractante de zinc; separar la solucion organica enriquecida en zinc de un extractante de zinc de la solucion reducida en zinc acuosa amoniacal de carbonato de amonio; poner en contacto la solucion organica enriquecida en zinc con una solucion acuosa acida, lo que produce una solucion acuosa acida enriquecida en zinc y una solucion organica reducida en zinc de un extractante de zinc; y recuperar el zinc de la solucion acuosa acida enriquecida en zincIt refers to a method for recovering zinc from an ammoniacal aqueous zinc solution of ammonium carbonate, wherein the method comprises the steps of: contacting the ammoniacal aqueous zinc solution of ammonium carbonate with an organic solution of an extractant of zinc, so that a part of the zinc is transferred from the ammoniacal aqueous zinc solution of ammonium carbonate, which produces an ammoniacal aqueous zinc reduced solution of ammonium carbonate and a zinc-enriched organic solution of a zinc extractant; separating the organic zinc-enriched solution of a zinc extractant from the ammoniacal aqueous zinc-reduced solution of ammonium carbonate; contacting the zinc-enriched organic solution with an acidic aqueous solution, which produces a zinc-enriched acidic aqueous solution and a zinc-reduced organic solution of a zinc extractant; and recover the zinc from the zinc-enriched acidic aqueous solution
