Abstract
DONDE EL CALOR GENERADO POR LA BIOLIXIVIACION DE LOS CONCENTRADOS DE MINERALES SULFURADOS, EN AL MENOS UN REACTOR DE ESTANQUE AGITADO, SE TRANSFIERE DENTRO DE LA PILA EN LA CUAL OCURRE LA LIXIVIACION BIO-ASISTIDA. DICHO CALOR SE TRANSFIERE POR CALENTAMIENTO DE UN FLUIDO EN AL MENOS UN INTERCAMBIADOR DE CALOR ASOCIADO AL REACTOR, Y LUEGO SE DIRIGE EL FLUIDO CALENTADO A LA PILA. EL INTERCAMBIADOR INCLUYE UN SERPENTIN ENFRIADOR DENTRO DEL ESTANQUE DEL REACTOR. EL FLUIDO ES REFINO PROVENIENTE DE UNA PLANTA, QUE SE USA PARA TRATAR UNA SOLUCION LIQUIDA CARGADA PROVENIENTE DE LA PILA, Y DESPUES DE CALENTARLO, EL REFINO SE DEVUELVE A LA PILA COMO LIXIVIANTE. EL REFINO ES PRODUCIDO POR TECNICAS DE EXTRACCION POR SOLVENTE APLICADAS A LA PILA. . LOS CONCENTRADOS SE SELECCIONAN DE Cu, Ni, Zn, Au Y OTROS CONCENTRADOS SULFURADOS. EL REACTOR SE OPERA A UNA TEMPERATURA ENTRE 60°C Y 80°C, USANDO MICROORGANISMOS TERMOFILOS EXTREMOS, MESOFILOS O TERMOFILOS MODERADOS
