Abstract
UN PROCESO PARA ELIMINAR EL HIERRO Y MANGANESO DE SOLUCIONES DE CLORURO DE CINC QUE CONTIENEN DE ACIDO HIDROCLORICO, TENIENDO UNA CONCENTRACION DE ION CINC ENTRE 50 Y 500 GM/L, UNA CONCENTRACION DE IONES DE HIERRO ENTRE 1 Y 70 GM/L, Y UNA CONCENTRACION DE MANGANESO ENTRE 10 Y 200 PPM, COMPRENDIENDO UNA NEUTRALIZACION DE ACIDO LIBRE; UN PRIMER PASO DE OXIDACION DE IONES FERROSOS A IONES FERRICOS POR MEDIO DE UN PRIMER AGENTE OXIDIZANTE SELECCIONADO DEL GRUPO QUE CONSTA DE CLORATO DE SODIO, PEROXIDO DE HIDROGENO, HIPOCLORITO DE SODIO, CLORITO DE SODIO; Y UNA PRECIPITACION DE HIERRO COMO UN COMPONENTE CON FORMULA (1) EN LA FORMA DE PARTICULAS CRISTALINAS FACILMENTE FILTRABLES. DESPUES DE LA INICIACION DE LA CRISTALIZACION ES AÑADIDO UN SEGUNDO AGENTE OXIDIZANTE FORMADO POR PERMANGANATO DE POTASIO, TAL QUE EL MANGANESO ES PRECIPITADO COMO MNO2; ENTONCES EL COMPONENTE CON FORMULA (1) Y MNO2 SON ELIMINADOS JUNTOS POR FILTRACION.
