Abstract

_(PROCEDIMIENTO PARA LA ELIMINACION DE MOLIBDENO A PARTIR DE SOLUCIONES ACUOSAS DE SALES . CONSISTEN EN PONER EN CONTACTO LA SOLUCION SALADA CON UNA CARGA DE DIOXIDO DE MANGANESO PREPARADA POR VIA ELECTROQUIMICA Y LLEVADA A FORMA GRANULAR, DE TAMAÑO 0,05 A 2 MM. EL PH DE LA SOLUCION DE SAL ES INFERIOR A 4. LA TEMPERATURA DEL PROCESO OSCILA ENTRE 20 Y 95 C. LA CARGA DE MN 02 SE EFECTUA TRATANDOLA CON UNA LEJIA DE SOSA CUYA CONCENTRACION ES AJUSTADA DE FORMA QUE DESPUES DE HABERSE ESTABLECIDO EL EQUILIBRIO DE DESORCION, LA SOLUCION RESULTANTE CONTIENE TODAVIA AL MENOS 2% EN PESO DE LEJIA DE SOSA LIBRE.
