Abstract

La invención se refiere a un método para producir artículos prensados que contienen óxido de hierro a partir de portadores de hierro oxídico de grano fino mediante la producción de una mezcla que comprende portadores de hierro oxídico de grano fino, bentonita como un aglutinante, y agua, presionando la mezcla y endureciendo los artículos prensados verdes obtenidos durante el prensado, así como artículos prensados producidos mediante el método y al uso de los artículos prensados como portadores de hierro grumosos; de acuerdo con la invención, después que los componentes de la mezcla han sido mezclados, dicha mezcla es sometida a un proceso de amasado de al menos 3 minutos y hasta 30 minutos, el cual es seguido por el prensado. Los artículos prensados son producidos sin algún proceso de acidificación.
