Abstract

Procedimiento de fundir mineral ciacífero oxidado con material reductor carbonáceo sólido en un horno de arco eléctrico con la consiguiente producción de una escoria virtualmente libre del cinc y vapor de cinc metálico capaz de condensarse predominantemente en cinc metálico macizo; que comprende : establecer en la composición de la carga un contenido de óxido de hierro suficiente par proveer después de su reducción parcial o por lo menos 1-1/2% de paso de óxido de hierro (calculado como Fe) en la escoria fundida y un cuerpo de un producto de hierro fundido que está debajo de un cuerpo de dicha escoria; proporcionar la cantidad de material reductor al óxido de hierro y otros componentes de óxidos metálicos fácilmente reducibles de la carga para efectuar la reducción virtualmente completo de dichos otros componentes de óxidos metálicos al paso que se efectua la reducción de solo tal porción del componente óxido de hierro de la carga que deje en la escoria por lo menos 1-1/2% pero no más de unos 6% de peso de óxido de hierro (calculado como Fe); introducir la carga en el horno en estado seco y suelto engendrar el calor de fusión para dicha reducción dentro del horno por un arco eléctrico en contacto con el cuerpo de escoria fundida y efectuar la reducción en una zona de fusión encima del cuerpo de la escoria fundida y fuera de contacto directo con dicho arco fundiéndose así la carga a temperatura no superior a 1450º C.
