Abstract

El propósito de la presente invención es proporcionar un método para eluir Ca de la escoria de fabricación de acero de manera que pueda eluirse una gran cantidad de Ca de la escoria de fabricación de acero en una solución acuosa que contiene dióxido de carbono. La presente invención se ejecuta, en este orden: un paso para eliminar un compuesto que contiene hierro de la escoria de fabricación de acero realizando una separación magnética en la escoria de fabricación de acero; y un paso para poner en contacto la escoria de fabricación de acero sometida a separación magnética con una solución acuosa que contiene dióxido de carbono. Además, la solución acuosa que contiene dióxido de carbono y la escoria de fabricación de acero se ponen en contacto entre sí mientras se pulveriza la escoria de fabricación de acero o se tritura la superficie de la escoria de fabricación de acero.
