Abstract

QUE COMPRENDE; a) EMPLEAR UNA SOLUCION DE ACIDO SULFURICO QUE TIENE UNA CONCENTRACION DE IONES DE CLORURO REGULADA ENTRE 6 g/L Y 18 g/L Y UN pH ENTRE 1,6 Y 2,5 COMO SOLUCION DE LIXIVIACION; Y, b) REALIZAR LIXIVIACION DE COBRE CON LA ADICION DE UNA BACTERIA OXIDANTE DE AZUFRE RESISTENTE A IONES DE CLORURO A LA SOLUCION DE LIXIVIACION, CUANDO SE RECUPERA COBRE A PARTIR DE MENAS DE SULFURO DE COBRE QUE CONTIENEN CALCOPIRITA. LA CONCENTRACION INICIAL DE Cu (II) Y DE Fe(II) SE REGULA ENTRE 0,5 g/L Y 5 g/L. LA BACTERIA OXIDANTE ES DE UNA ACIDITHIOBACILLUS sp. CEPA TTH-19A (NITE P-164)
