Abstract

DONDE LA RECUPERACION COMPRENDE: a) SOMETER LA SUSPENSION A UN PROCESO DE BIOLIXIVIACION A UNA TEMPERATURA QUE ESTA ENTRE 40°C Y 100°C, USANDO MICROORGANISMOS MESOFILOS, TERMOFILOS MODERADOS O TERMOFILOS; b) SUMINISTRAR A LA SUSPENSION, GAS QUE CONTIENE MAS DE 21% DE OXIGENO, EN VOLUMEN; c) REMOVER Cu Y Fe DEL RESIDUO DE BIOLIXIVIACION; d) RECUPERAR Zn DESDE DICHO RESIDUO, USANDO EXTRACCION POR SOLVENTES Y ELECTRORECUPERACION PARA PRODUCIR CATODOS DE Zn METALICOS; e) PURIFICAR CON POLVO DE Zn, POR PRECIPITACION Y ELECTRORECUPERACION, EL RESIDUO, PARA PRODUCIR CATODOS METALICOS DE Zn; Y, f) SUMINISTRAR EL ELECTROLITO GASTADO DE LA ELECTRORECUPERACION, A (a), UN PROCESO EXTERNO DE LIXIVIACION EN PILAS Y UNA ETAPA DE LIXIVIACION DE ZnO. PARA REMOVER EL Fe DEL PASO (c), SE ADICIONA CALIZA AL RESIDUO. EL OXIGENO GENERADO DURANTE LA ELECTRORECUPERACION, SE AGREGA A (b) o (a). EL ACIDO GENERADO EN EL REFINADO, DURANTE LA EXTRACCION POR SOLVENTES, SE NEUTRALIZA CON CALIZA O MINERAL DE OXIDO DE Zn o CONCENTRADO, PARA PRODUCIR YESO Y CO2, Y PARA PRECIPITAR EL Fe COLIXIVIADO, SUMINISTRANDO EL C02 FORMADO A (a). ADEMAS, SE DEBE MANTENER LA CONCENTRACION DE OXIGENO DISUELTO EN UN RANGO QUE VA DE 0,0002 Kg/m3 A 0,01 Kg/m3, Y CONTROLAR EL CONTENIDO DE CO2 EN LA SUSPENSION EN UN RANGO QUE VA DE 0,5% A 5% EN VOLUMEN
