Abstract

La invención se refiere a un método para la reducción de un material que contiene óxido de metal (2), en donde se usa un gas reductor que se obtiene usando amoníaco NH3. El gas reductor se suministra a un reactor de reducción (2) que contiene el material que contiene óxido de metal, y se descarga un gas de tragante desde el reactor de reducción. Se utiliza al menos una subcantidad del gas de tragante como componentes en la preparación del gas reductor, opcionalmente después de que se prepara el gas de tragante. Un dispositivo (1) para la reducción del material que contiene óxido de metal (3) comprende un reactor de reducción (2), una línea de descarga de gas de tragante (4) para descargar el gas de tragante fuera del reactor de reducción (2), al menos una línea de suministro para una contribución de amoníaco (7), un sistema de preparación (6) para preparar el gas reductor, al menos una línea de suministro para la contribución de amoníaco (7) que conduce al sistema de preparación, y una línea de alimentación (8) para alimentar el gas reductor y/o un precursor del gas reductor al reactor de reducción (2), en donde la línea de descarga de gas de tragante (5) conduce al sistema de preparación (6).
