Abstract

QUE COMPRENDE: a) SOMETER UN CONCENTRADO DE SULFURO DE ZINC A LIXIVIACION POR PRESION CON UNA SOLUCION DE LIXIVIACION ACIDA QUE CONTIENE POR LO MENOS 15 g/L DE Fe EN SOLUCION, HASTA PRODUCIR UNA SOLUCION DE Zn Y UN RESIDUO DE LIXIVIACION SOLIDO QUE CONTIENE Fe; b) SOMETER LA SOLUCION DE Zn A EXTRACCION POR SOLVENTE DEL Zn, PARA PRODUCIR UN REFINADO Y UNA SOLUCION MATRIZ DE Zn; Y, c) SOMETER LA SOLUCION MATRIZ DE Zn A ELECTROEXTRACCION, PARA RECUPERAR Zn Y PRODUCIR UN ELECTROLITO AGOTADO RESULTANTE QUE SE RECICLA A LA EXTRACCION POR SOLVENTE DE Zn. LA LIXIVIACION POR PRESION ES EFECTUADA EN DOS ETAPAS CONTRACORRIENTE: UNA PARA PRODUCIR LA SOLUCION DE Zn Y UN RESIDUO INTERMEDIO, Y OTRA DONDE EL RESIDUO INTERMEDIO ES LIXIVIADO CON LA SOLUCION ACIDA DE (a). ADEMAS, SE REFIERE A UN METODO PARA SEPARAR Fe DE UN REFINADO QUE LO CONTIENE, QUE COMPRENDE LIXIVIAR POR PRESION UNA MENA DE SULFATO DE Zn CON DICHO REFINADO PARA PRODUCIR UN RESIDUO SOLIDO DE LIXIVIACION QUE CONTIENE Fe Y UNA SOLUCION DE Zn
