Abstract

Procedimiento de recuperación de metales reciclables, en residuos sólidos de las industrias siderúrgicas, por destilación y reducción carbotérmica, en los estados sólido y líquido. El procedimiento de reciclado, consiste en la aplicación sobre los residuos (previamente mezclados con carbón y un fundente, y aglomerados), de un tratamiento inicial de destilación con gases parcialmente oxidados y a alta temperatura, mediante el que se obtiene, dos fracciones en estado sólido, con los constituyentes volátiles, (concentrado de ZnO), y no volátiles, (rica en hierro metálico, denominado en lo sucesivo DRI), dotadas de unas características y estado, que mejoran la eficacia de la aplicación posterior, a cada uno de ellos, de tratamientos específicos de reciclado, (hidrometalúrgico y de fusión reductora, respectivamente), para la recuperación de los metales valiosos que contienen, y/o poder reducir los costes de vertido.
