Abstract

LA PRESENTE INVENCION SE REFIERE A UN PROCEDIMIENTO PARA EL TRATAMIENTO DE POLVO METALICO (A), PREFERIBLEMENTE DESPERDICIO OXIDADO, PARTICULARMENTE POLVO DE GALVANIZACION, Y/O HUMO DE ACERIAS (B). DICHO PROCEDIMIENTO SE CARACTERIZA PORQUE COMPRENDE: A) AL MENOS UNA ETAPA (1) DE LIXIVIACION ACIDA CON ACIDO CLORHIDRICO O ACIDO AGOTADO, EN CONDICIONES TALES QUE SE LOGRE TRANSFERIR LOS METALES CONTENIDOS EN DICHO POLVO HACIA LA DISOLUCION; B) UNA ETAPA (4) DE OXIDACION LLEVADA A CABO SOBRE DICHA DISOLUCION DE LIXIVIACION PARA CONVERTIR Y PRECIPITAR EL HIERRO EN ESTADO TRIVALENTE; C) UNA ETAPA (9) PARA LA CEMENTACION DE LAS IMPUREZAS METALICAS, LLEVADA A CABO SOBRE LA DISOLUCION PROCEDENTE DE LA ETAPA B) DESPUES DE LA SEPARACION DEL RESIDUO INSOLUBLE, Y REALIZADA MEDIANTE LA ADICION DE CINC EN POLVO, CLORURO DE COBRE Y POSIBLEMENTE TRIOXIDO DE ANTIMONIO, PARA EFECTUAR LA PRECIPITACION DE LOS METALES MAS NOBLES QUE EL CINC EN LA SERIE ELECTROQUIMICA; D) UNA ETAPA (14) DE ELECTROLISIS LLEVADA A CABO SOBRE EL ELECTROLITO PROCEDENTE DE LA ETAPA (9) DE CEMENTACION, A FIN DE PRODUCIR CINC ELECTROLITICO Y CLORO GASEOSO.
