Abstract
La presente se refiere a un procedimiento para el acondicionamiento de escorias de acería para producir un ligante mineral hidráulico con elevado potencial de endurecimiento y para la recuperación de hierro. Para ello se ha previsto proporcionar un producto de carga que presenta escoria de acería con MnO. Este producto de carga se continúa procesando como masa fundida mediante la incorporación de agentes reductores en la masa fundida. Con esto, en la parte mineral de la masa fundida se debe alcanzar un estándar de cal entre 90 y 110. A continuación se enfría de manera definida la masa fundida y se separa mecánicamente hierro elemental de la masa fundida solidificada. Después, la masa fundida solidificada se destina para ser usada como ligante mineral hidráulico. Además la presente se refiere a un ligante mineral hidráulico. Reivindicación 14: Ligante mineral hidráulico, producido en particular según un procedimiento de acuerdo con una de las reivindicaciones 1 a 13, caracterizado porque presenta una composición mineralógica de cómo mínimo el 40% en masa de C₃S y un estándar de cal de aproximadamente 90 a 110.
