Abstract

PERFECCIONAMIENTO EN EL PROCEDIMIENTO BAYER PARA FORMAR ALUMINA. CONSISTE EN OXIDAR UN LIQUIDO QUE CONTIENE MATERIA ORGANICA, ALUMINATO SODICO, ALO3NA3 (PROCEDENTE DE LA DIGESTION DE BAUXITA), CARBONATO SODICO, CO3NA2 (EN UNA CONCENTRACION DE 50 GR/L), CON DIOXIDO DE MANGANESO, MNO2 (CON UNA CONCENTRACION DE 200 GR/L), A UNA TEMPERATURA COMPRENDIDA ENTRE 100 Y 200JC, DURANTE UN TIEMPO COMPRENDIDO ENTRE 0,5 Y 4 HORAS, EN UN REACTOR DE LECHO FLUIDO, PARA OBTENER, COMO PRODUCTO ORGANICO OXIDADO, OXALATO. SIENDO: LA RELACION DE CONCENTRACION MOLARES DE IONES MANGANESO A IONES OXALATO MAYOR QUE 3; Y LA RELACION EN PESO DE DIOXIDO DE MANGANESO A BAUXITA MENOR DE 0,02.
