Abstract

El propósito de la presente invención es proporcionar un método para eluir calcio a partir de escoria de acero de manera que se pueda eluir más calcio a una solución acuosa que contiene dióxido de carbono a partir de la escoria de acero. La presente invención comprende llevar a cabo, en el siguiente orden, una etapa de someter un compuesto de calcio contenido en la escoria de acero a hidratación y una etapa de poner en contacto la escoria de acero, sometida a hidratación, con una solución acuosa que contiene dióxido de carbono. Además, en la presente invención, la solución acuosa que contiene dióxido de carbono se pone en contacto con la escoria de acero mientras la escoria de acero es pulverizada o la superficie de la escoria de acero es molida. Como un resultado de estos métodos se puede eluir fácilmente más calcio hacia la solución acuosa que contiene dióxido de carbono a partir de la escoria de acero.
