Abstract

DONDE LA RECUPERACION COMPRENDE: a) SEPARAR DICHOS CONCENTRADOS POR FLOTACION Y OXIDACION BIOLOGICA, PARA PRODUCIR: 1) UNA PRIMERA SOLUCION DE LIXIVIACION QUE CONTIENE PREDOMINANTEMENTE COBRE; Y, 2) UNA SEGUNDA SOLUCION DE LIXIVIACION QUE CONTIENE PEREDOMINANTEMENTE NIQUEL; b) SOMETER (1) Y (2), CADA UNO, A UN PROCESO DE RECUPERACION POR EXTRACCION POR SOLVENTES PARA PRODUCIR UN REFINADO CON ALTO CONTENIDO DE ACIDO SULFURICO; Y, c) RECIRCULAR AL MENOS PARTE DEL REFINADO AL PASO (a). LA OXIDACION BIOLOGICA DEL CONCENTRADO DE COBRE SE EFECTUA A UNA TEMPERATURA ENTRE 65° Y 80°C, PARA MANTENER ACTIVOS MICROORGANISMOS TERMOFILOS O BACTERIAS TERMOTOLERANTES O TERMOFILAS QUE DISUELVEN CALCOPIRITA COMO SULFATO DE COBRE; Y LA DEL CONCENTRADO DE NIQUEL SE EFECTUA A UNA TEMPERATURA ENTRE 40°C Y 45°C PARA MANTENER ACTIVOS BACTERIAS MESOFILAS O TERMOTOLERANTES MODERADAS QUE DISUELVEN PENTLANDITA COMO SULFATO DE NIQUEL. EL SULFATO DE NIQUEL SE SOMETE A EXTRACCION DE COBRE, ANTES DE EFECTUAR LA RECUPERACION DEL NIQUEL
