Abstract

El zinc y el plomo usualmente están presentes concomitantemente en los minerales y relaves de Zn-Pb. Un novel proceso hidrometalúrgico no contaminante para lixiviar y recuperar selectivamente el zinc (Zn) de un mineral compuesto que contiene sulfuro de plomo (Pb) y zinc, roca triturada no tratada o partículas de mineral sin consolidar, sobrantes y/o zinc sulfídico aglomerado y sin aglomerar que contiene desperdicios sin necesidad de desarrollar la operación de refinamiento y fundición. Se ha comprobado que la combinación del oxidante seleccionado y el hidróxido del metal alcalino es efectiva. Un lixiviante consistente de Ej. una mezcla de hidróxido de sodio (NaOH) e hipoclorito de sodio (NaOCl) es empleada para disolver selectivamente el sulfuro de zinc a un pH alto a temperatura y presión estándar (TPE). La cinética del lixiviado junto con el efecto de la concentración variante (preferiblemente del hidróxido de sodio y el hipoclorito de sodio) fue investigada sistemáticamente. La mena explotable que contiene una variedad de minerales Ej. Sulfuros y carbonatos también puede ser tratado convenientemente para recuperar el zinc selectiva y cuantitativamente como un carbonato de zinc de alta pureza. Esta tecnología puede ser utilizada in-situ o ex-situ basado en la disponibilidad de un tipo particular de depósito mineral o mena explotable.
