Abstract

DONDE LA RECUPERACION COMPRENDE: a) LIXIVIAR LA SUSPENSION, USANDO UNA SOLUCION ACIDA DE SULFATOS FERRICO Y DE COBRE; b) SOMETER LA SUSPENSION A UNA BIO-LIXIVIACION, A UNA TEMPERATURA QUE ESTA ENTRE 40°C Y 100°C, USANDO MICROORGANISMOS MESOFILOS, TERMOFILOS MODERADOS O TERMOFILOS; c) SUMINISTRAR A LA SUSPENSION, GAS QUE CONTIENE MAS DE 21% DE OXIGENO, EN VOLUMEN; d) REMOVER ARSENIATO FERRICO DESDE EL RESIDUO DE LIXIVIACION, POR PRECIPITACION; e) RECUPERAR COBRE DESDE DICHO RESIDUO, USANDO EXTRACCION POR SOLVENTES Y ELECTRORECUPERACION; Y, f) NEUTRALIZAR DICHO RESIDUO, Y LLEVAR EL CO2 GENERADO AL PASO (c) o (b) JUNTO AL OXIGENO GENERADO DURANTE LA ELECTRORECUPERACION. EL REFINADO PRODUCIDO EN LA EXTRACCION, SE SUMINISTRA A (b) Y A UN PROCESO EXTERNO DE LIXIVIACION EN PILAS. LA SUSPENSION CONTIENE AL MENOS, SULFUROS ARSENICALES DE COBRE Y MINERALES SULFURADOS QUE LO CONTIENEN, REFRACTARIOS A LA LIXIVIACION POR MESOFILOS. ADEMAS, SE DEBE MANTENER LA CONCENTRACION DE OXIGENO DISUELTO EN UN RANGO QUE VA DE 0,0002 Kg/m3 A 0,01 Kg/m3, Y CONTROLAR EL CONTENIDO DE CO2 EN UN RANGO QUE VA DE 0,5% A 5% EN VOLUMEN
