Abstract

SE DESCRIBE UN PROCESO PARA EL TRATAMIENTO DE SOLUCION DE SULFURO CAUSTICO MEDIANTE OXIDACION HUMEDA EN UN SISTEMA DE ALEACION BASADO EN NIQUEL EN EL QUE LA SOLUCION SE ANALIZA PRIMERO PARA VARIEDADES CONSUMIDORAS DE ALCALINIDAD Y PARA ALCALINIDAD NO SULFURICA. SI SE PRESENTAN VARIEDADES CONSUMIDORAS DE ALCALINIDAD EN EXCESO COMPARADO CON ALCALINIDAD NO SULFURICA LA ALCALINIDAD NO SULFURICA ADICIONAL SE AÑADA A LA SOLUCION BRUTA DE MANERA QUE EL EXCESO DE ALCALINIDAD ESTE PRESENTE DURANTE EL TRATAMIENTO DE OXIDACION, IMPIDIENDO ASI CORROSION EXCESIVA AL SISTEMA DE ALEACION BASADO EN NIQUEL.
