Abstract

El método de fundir un mineral cincífero oxídico con material reductor carbonáceo en un horno eléctrico con la producción resultante de vapor de cinc metálico esencialmente exento de impurezas formadoras de polvo y una escoria fundida esencialmente libre de cinc que comprende cargar el mineral cincífero y el material reductor carbonáceo en un horno en estado suelto y seco establecer en la composición de la carga un contenido en óxido de hierro suficiente para dar por reducción parcial del mismo una masa de producto de hierro fundido subyacente a dicha escoria y al menos 1 1/2& en peso de óxido de hierro (calculado como Fe) en la escoria fundida correlacionar la cantidad de materia reductor con los componentes de óxido de cinc y de óxido de hierro de la carga de modo que se efectúa reducción de todo el componente de óxido de cinc del mineral a cinc metálico mientras se efectúa reducción de sólo tal porción del componente de óxido de hierro de la carga que queda en la escoria al menos 1 1/2% pero no más de aproximadamente 6% en peso de óxido de hierro (calculado como Fe) ajustar el contenido de cal y sílice de la carga para producir dicha escoria en la cual la relación de CaO a cae dentro de la escala de 0 8:1 a 1 4:1 y fundir dicha carga seca sobre la superficie de la escoria fundida a una temperatura que no excede de 1450ºC.
