Abstract

LA EXTRACCION DE METALES QUE CONSUMEN PRODUCTOS QUIMICOS DE BLANQUEO PROCEDENTES DE FLUIDOS DE TRATAMIENTO EN UNA FABRICA DE PASTA DE MADERA (PAPEL), SE FACILITA TRATANDO LA PULPA EN UNA FASE ACIDICA O NEUTRA, PARA DISOLVER METALES, LAVADO O ESPESAMIENTO DE PULPA, PARA OBTENER UN FILTRADO CONTENIENDO METALES DISUELTOS, Y DESPUES USANDO UN LIQUIDO ALCALINO PARA AJUSTAR EL PH DEL FILTRADO, Y HACER QUE SE DISUELVAN METALES HASTA PRECIPITARSE. EL LIQUIDO ALCALINO SE TRATA PREVIAMENTE CON BIOXIDO DE CARBONO PARA REDUCIR EL CONTENIDO DE SULFURO Y AUMENTAR EL CONTENIDO DE CARBONATO DEL MISMO, SIENDO LOS LIQUIDOS PREFERENTES LICOR VERDE Y LICOR BLANCO. EL FILTRADO DEL CONTENIDO DE METAL REDUCIDO SE USA EN LA PLANTA DE BLANQUEO DE LA FABRICA DE PASTA DE MADERA, PARA OBTENER PRODUCTOS QUIMICOS DE BLANQUEO, COMO LIQUIDO BLANCO, ETC. EL TRATAMIENTO DEL LIQUIDO ALCALINO CON BIOXIDO DE CARBONO SE PRACTICA TIPICAMENTE LIMPIANDO EL LICOR CON GAS DE BIOXIDO DE CARBONO, POR EJEMPLO, USANDO UN DEPURADOR DE COLUMNA DE PLACAS O UN DEPURADOR DE ACONDICIONAMIENTO FIJO.
