Characterization of blast furnace flue dust – a multi analytical techniques approach

The blast furnace flue dust has potential reuse application in iron making process via the sinter making route mainly due to its high carbon content. The specific aim of this study was to use different analytical techniques like chemical analysis, X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy, scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM-EDS) and petrography to identify the different phases present in the blast furnace flue dust of Tata Steel Limited, Jamshedpur and discuss on possible use of suitable separation techniques for economic utilization of flue dust and put those separated fractions for the innovative industrial applications.
