Abstract
El método de fundir un mineral cincífero con un material reducto carbonáceo sólido en un horno de arco eléctrico con la producción resultante de una mata fundida una escoria fundida sustancialmente exenta de cinc y vapor de cinc metálico capaz de ser condensado predominantemente a cinc metálico macizo que comprende establecer en una carga de mineral cincífero oxidado que contiene cantidades significantes de hierro y al menos un metal del grupo consistente en cobre plata y oro una cantidad de azufre suficiente para formar una mata con virtualmente todo el metal de dicho grupo y al menos una parte del hierro establecer además en la composición de la carga una cantidad del material reductor suficiente para reducir todo el óxido de cinc introducir la carga en el horno en estado suelto y saco generar el calor de fusión para dicha reducción dentro del horno por un arco a eléctrico en contacto con la masa de escoria fundida y efectuar dicha reducción en una zona de fusión encima de la mesa de escoria fundida y fuera del contacto directo con dicho arco con lo cual la fusión de la carga se efectúa a una temperatura que en sustancia no excede de 1450ºC.The method of smelting a zinc ore with a solid carbonaceous reductant material in an electric arc furnace with the resulting production of a molten mat a substantially zinc-free molten slag and metallic zinc vapor capable of being predominantly condensed to solid metallic zinc comprising establish in an oxidized zinc ore charge containing significant amounts of iron and at least one metal from the group consisting of copper, silver and gold, an amount of sulfur sufficient to form a mat with virtually all the metal of that group and at least a part of the iron also establish in the composition of the charge an amount of the reducing material sufficient to reduce all the zinc oxide, introduce the charge into the furnace in a loose state and generate the heat of fusion for said reduction within the furnace by an electric arc in contact with the mass of molten slag and effect said reduction in a melting zone above the table molten slag and out of direct contact with said arc whereby the melting of the charge takes place at a temperature that does not substantially exceed 1450 ° C.
