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)WHAT YOU UNDERSTAND; a) USE A SULFURIC ACID SOLUTION THAT HAS A CHLORIDE ION CONCENTRATION REGULATED BETWEEN 6 g / L AND 18 g / L AND A pH BETWEEN 1.6 AND 2.5 AS A LEACHING SOLUTION; AND, b) PERFORM COPPER LEACHING WITH THE ADDITION OF AN OXIDIZING BACTERIA OF SULFUR RESISTANT TO CHLORIDE IONS TO THE LEACHING SOLUTION, WHEN COPPER IS RECOVERED FROM MINES OF COPPER SULFIDE CONTAINING CHALCOPYRITE. THE INITIAL CONCENTRATION OF Cu (II) AND Fe (II) IS REGULATED BETWEEN 0.5 g / L AND 5 g / L. THE OXIDIZING BACTERIA IS FROM AN ACIDITHIOBACILLUS sp. CEPA TTH-19A (NITE P-164)
