Abstract

Se proporcionan métodos para reducir el contenido de metal de cobre de la chatarra de acero triturada. El método incluye separar continuamente una primera fracción de chatarra de acero de una cantidad de chatarra de acero concurrentemente con la separación de una segunda fracción de la cantidad de chatarra de acero; separar continuamente la segunda fracción y proporcionar una fracción no magnética y, concurrentemente, una tercera fracción de chatarra de acero; moler la fracción no magnética seguido de la separación magnética para proporcionar una cuarta fracción de chatarra de acero y, concurrentemente, una fracción no magnética enriquecida; combinar continuamente la primera fracción de chatarra de acero, la tercera fracción de chatarra de acero y la cuarta fracción de chatarra de acero para obtener un producto de chatarra de acero combinado que comprende chatarra de acero con contenido de metal de cobre reducido; e introducir el producto de chatarra de acero combinado a un horno de arco eléctrico. También se proporcionan sistemas para reducir el contenido de metal de cobre de la chatarra de acero triturada.
