Abstract

a proposta da presente invenção é proporcionar um método para eluição de cálcio de escória de aço, tal que mais cálcio pode ser eluído em uma solução aquosa contendo dióxido de carbono a partir da escória de aço. a presente invenção compreende efetuar, na seguinte ordem, uma etapa de submeter um composto de cálcio contido na escória de aço à hidração, e uma etapa de trazer a escória de aço submetida à hidratação em contato com a solução aquosa contendo dióxido de carbono. além disso, na presente invenção, a solução aquosa contendo dióxido de carbono é trazida em contato com a escória de aço, enquanto que a escória de aço está sendo pulverizada, ou a superfície da escória de aço está sendo triturada. como um resultado destes métodos, mais cálcio pode ser fracilmente eluído na solução aquosa contendo dióxido de carbono a partir da escória de aço.
