Abstract

Procedimiento para la recuperación de plomo y cinc de polvos de acería eléctrica y reciclado del residuo. La presente invención contempla la recuperación del cinc y plomo de los polvos de acerías eléctricas de arco y el reciclado del residuo a la propia acería. Para ello, se utiliza un procedimiento pirotérmico, basado en los que se aplican para los minerales de cinc, con una serie de modificaciones que marcan la novedad del proceso; se contempla la reducción por carbón de los óxidos de Zn y Pb, y la separación por volatilización de los dos metales, lo que constituye una novedad del proceso; así, una vez eliminada la mayor parte del cinc y plomo de los polvos, el residuo puede devolverse a la acería. El proceso emplea un exceso de coque sobre el estequiométrico necesario para la reducción de los óxidos, y el calentamiento de la carga. El alto volumen de gases producidos, unido al bajo contenido de plomo en el material a tratar, permite eliminarse este elemento por vaporización. Finalmente,el proceso cierra su ciclo utilizando los gases producidos para cogenerar energía.
