Abstract

QUE COMPRENDE: a) PROVEER UNA PILA DE MENA, AIREADA EN O CERCA DE UNA BASE DE LA MISMA, CONTENIENDO CALCOPIRITA PARA OXIDAR EN ELLA SULFUROS MINERALES, LA PILA CONTENIENDO Y/O SIENDO INOCULADA CON UN CULTIVO BACTERIAL QUE OXIDE SULFUROS QUE O BIEN NO OXIDE EL FIERRO HASTA CONVERTIRLO EN OXIDO FERRICO, O RESULTE INEFICIENTE HACIENDOLO; b) PROVEER POR LO MENOS UN PRIMER ESTANQUE DE SOLUCION LIXIVIADORA, DESDE EL CUAL LA SOLUCION DE ALIMENTACION ES LLEVADA A LA PILA Y QUE RECIBE SOLUCION LIXIVIADORA DE LA PILA; Y, c) EXUDAR UNA PORCION DE LA SOLUCION LIXIVIADORA Y PASARLA A UN SISTEMA PARA LA RECUPERACION DE METALES. DICHO PRIMER ESTANQUE ES MANTENIDO CON UNA CONCENTRACION BAJA DE OXIDO FERRICO RESPECTO A LA CONCENTRACION DE HIERRO, Y MANTENIDO CON UN POTENCIAL DE REDUCCION DE OXIDACION POR DEBAJO DE 500 mV. LA OXIDACION DE CALCOPIRITA SE LOGRA CON BACTERIAS QUIMIOLITOTROPICAS
