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 CALDUSINCLUDING: a) SUBMITTING THE CONCENTRATE TO A PRIMARY, MESOPHILIC AND MODERATE THERMOPHILIC BIO-LEACHING PROCESS, AT A TEMPERATURE BETWEEN 35 ° C AND 50 ° C CONTROLLING THE pH BETWEEN 1.2 AND 1.7 AND IN A SERIES OF REACTOR PONDS WITH CONTINUOUS AGITATION, TO LEACH SULFIDES IN THE CONCENTRATE; AND, b) SUBMIT THE RESIDUE FROM THE PRIMARY BIO-LEACHING PROCESS TO A SECONDARY THERMOPHILIC BIO-LEACHING PROCESS, AT A TEMPERATURE BETWEEN 65 ° C AND 80 ° C CONTROLLING THE pH BETWEEN 1 AND 1.7, TO RELEASE AT LEAST ONE METAL BASE FROM THE WASTE RECOVERED FROM THE METAL IN SOLUTION AND RECOVERING THE BASE METAL FROM THE SOLUTION OBTAINED FROM THE SECONDARY BIO-LIXIVIATION PROCESS. THE CONCENTRATE IS PRE-LEACHED, BEFORE THE PRIMARY BIO-LEACHING PROCESS, USING THE LEACHING SOLUTION FROM THE PRIMARY AND SECONDARY BIO-LEACHING PROCESSES, AND THEN THE pH OF THE OBTAINED SOLUTION IS ADJUSTED TO AT LEAST 2 AT A TEMPERATURE BETWEEN 60 ° C and 80 ° C. AIR IS SUPPLIED TO THE CONCENTRATE, WITH AN OXYGEN CONTENT BETWEEN 95% AND 98% AND WITH A CARBON DIOXIDE CONTENT BETWEEN 1% AND 5%, DURING AT LEAST PART OF THE BIO-LEACHING PROCESSES. IN (a) A MIXED CROP CONTAINING LEPTOSPIRILLUM FERROOXIDANS AND ACIDITHIOBACILLUS CALDUS IS USED
