Resumen
En este trabajo se estudiaron muestras de hierro, obtenidas mediante separación magnética de cenizas volantes, procedentes de una estación termoeléctrica de Boyacá, Colombia. Se realizó la caracterización morfológica de las partículas mediante microscopía electrónica de barrido. La composición elemental y su estructura cristalina fueron estudiadas mediante espectroscopia de energía dispersiva de rayos X y difracción de rayos X, respectivamente. Los resultados obtenidos muestran la presencia de ferrósferas y cenósferas, que son compuestos irregulares y rugosos con alto contenido en hierro. Las fases mineralógicas presentes en las muestras son principalmente magnetita y hematita, con algunas trazas de mullita. Estas fases pueden aportar propiedades magnéticas y ampliar el rango de aplicaciones de estas partículas a partir de un simple proceso de separación en las cenizas volantes.
