Abstract
SE PRESENTA UN METODO PARA HACER FUNCIONAR UN SISTEMA CONTINUO DE OXIDACION HUMEDA PARA DESTRUIR EL CIANURO EN EL CIANURO CAUSTICO Y EN LOS DESHECHOS METALICOS CUYA ESCALA DESPUES DEL CALENTAMIENTO COMPRENDE LA INTRODUCCION DE LA BASURA EN BRUTO DENTRO DEL REACTOR DE OXIDACION HUMEDA (14) SIN CALENTAR MIENTRAS UNA MEZCLA DE AGUA DE DISOLUCION CALENTADA Y OXIGENO CONTENIENDO GAS SE INTRODUCE DENTRO DEL REACTOR MEDIANTE UNA ENTRADA SEPARADA (12). EL REACTOR (14) ESTA PROVISTO DE UN PAR DE LINEAS EFLUYENTES CONMUTADAS CON VALVULAS (16, 17) Y QUE SE CORRESPONDEN A LAS LINEAS CONMUTADAS MEDIANTE VALVULAS (44, 50) PARA LA INTRODUCCION DEL ACIDO DEL MINERAL DILUIDO DENTRO DE CADA LINEA DE EFLUYENTE EN EL SISTEMA DE PRESION. EL EFLUYENTE OXIDADO Y LOS GASES SALEN A TRAVES DE UNA LINEA DE EFLUYENTE PRIMARIA (16) MIENTRAS EL ACIDO DEL MINERAL DILUIDO FLUYE A TRAVES DE LA SEGUNDA LINEA DE EFLUYENTE (14) HACIA EL INTERIOR DEL REACTOR PARA EVITAR LA CONSTRUCCION DE COSTRA. PERIODICAMENTE LOS FLUJOS SECONMUTAN DE TAL FORMA QUE EL EFLUYENTE OXIDADO Y LOS GASES SALEN A TRAVES DE LA SEGUNDA LINEA EFLUYENTE (17) Y EL ACIDO DEL MINERAL DILUIDO FLUYE A TRAVES DE LA PRIMERA LINEA (16) HACIA EL INTERIOR DEL REACTOR PARA REMOVER LA COSTRA. EL EFLUYENTE OXIDADO Y LOS GASES SE ENFRIAN ENTONCES Y SE SEPARAN.
