Abstract

QUE COMPRENDE: a) SELECCIONAR UNA MENA SULFUROSA DE TAMANO MAXIMO DE PARTICULA DE 50 mm; b) FORMAR UN MONTON CON (a) Y BIOOXIDAR LA MENA CON MICROORGANISMOS ACIDOFILICOS A UNA TEMPERATURA PROMEDIO DE POR LO MENOS 30°C, PROPORCIONANDO AIRE AL FONDO DEL MONTON A UNA VELOCIDAD DE POR LO MENOS 5 L/m2 E IRRIGANDO LA PARTE SUPERIOR DEL MONTON CON UNA SOLUCION ACIDA QUE CONTIENE POR LO MENOS 0,04 g/L DE Fe Y HASTA 30 g/L DE ACIDO SULFURICO PARA PRODUCIR UNA SOLUCION DE LIXIVIACION MADRE CON UN CONTENIDO DE ACIDO PREDETERMINADO Y CONTENIDO DE Zn; c) SOMETER LA SOLUCION DE LIXIVIACION MADRE A NEUTRALIZACION Y EXTRACCION CON DISOLVENTE PARA OBTENER UNA SOLUCION DE Zn CONCENTRADA Y UN REFINADO; Y, d) RECUPERAR EL Zn DESDE LA SOLUCION CONCENTRADA POR MEDIO DE ELECTROEXTRACCION, YA SEA EN PRESENCIA O AUSENCIA DE Mn. ADEMAS, SE PROPORCIONA A LOS MICROORGANISMOS UN NUTRIENTE QUE COMPRENDE N EN FORMA DE UN SAL DE AMONIO, Y UNA FUENTE DE K y P. EL Zn ES EXTRAIDO DESDE LA MENA EN EL MONTON A UNA VELOCIDAD PROMEDIO DE 2,5 Kg.m2.d, CON LO CUAL LA CONCENTRACION DE ZINC EN LA SOLUCION ACIDA ES AUMENTADA HASTA 20 g/L. EL MONTON TIENE UNA ALTURA DE 2 m A 10 m
