Abstract
QUE COMPRENDE: a) SOMETER EL CONCENTRADO A UN PROCESO DE BIO-LIXIVIACION PRIMARIO, MESOFILICO Y TERMOFILICO MODERADO, A UNA TEMPERATURA ENTRE 35°C Y 50°C CONTROLANDO EL pH ENTRE 1,2 Y 1,7 Y EN UNA SERIE DE ESTANQUES REACTORES CON AGITACION CONTINUA, PARA LIXIVIAR SULFUROS EN EL CONCENTRADO; Y, b) SOMETER EL RESIDUO DEL PROCESO DE BIO-LIXIVIACION PRIMARIO A UN PROCESO DE BIO-LIXIVIACION TERMOFILICO SECUNDARIO, A UNA TEMPERATURA ENTRE 65°C Y 80°C CONTROLANDO EL pH ENTRE 1 Y 1,7, PARA LIBERAR AL MENOS UN METAL BASE DESDE EL RESIDUO RECUPERADO DEL METAL EN SOLUCION Y RECUPERAR EL METAL BASE DESDE LA SOLUCION OBTENIDA DEL PROCESO DE BIO-LIXIVIACION TERMOFILICA SECUNDARIO. EL CONCENTRADO SE PRE-LIXIVIA, ANTES DEL PROCESO DE BIO-LIXIVIACION PRIMARIO, USANDO SOLUCION DE LIXIVIACION DE LOS PROCESOS DE BIO-LIXIVIACION PRIMARIO Y SECUNDARIO, Y LUEGO SE AJUSTA EL pH DE LA SOLUCION OBTENIDA A AL MENOS 2 A UNA TEMPERATURA ENTRE 60°C Y 80°C. SE SUMINISTRA AIRE AL CONCENTRADO, CON UN CONTENIDO DE OXIGENO ENTRE 95% Y 98% Y CON UN CONTENIDO DE DIOXIDO DE CARBONO ENTRE 1% Y 5%, DURANTE AL MENOS PARTE DE LOS PROCESOS DE BIO-LIXIVIACION. EN (a) SE USA UN CULTIVO MEZCLADO QUE CONTIENE LEPTOSPIRILLUM FERROOXIDANS y ACIDITHIOBACILLUS CALDUS
