X-ray diffraction (XRD) is a standard technique of characterizing structure of materials. The aim of this work is to identify and quantify carbonaceous components (coal, char and coke fines) in the off-gas blast furnace (BF) through the use of the XRD technique and ultimate analysis. The dust collected in the off-gas BF, which contains char, coke fines, metallic oxides, etc., was fractioned and chemically analyzed. In addition, the fractions were grounded, demineralized and analyzed by ultimate analysis and XRD. This technique reveals differences in crystallite size of the carbonaceous materials. The coke structure shows to be more ordered (bigger L c ) than the char structure. Based on these differences, it is possible to quantify the fines proportions of char and coke in the blast furnace flue dust. The estimated char proportion in the carbonaceous material of the flue dust is 7%.
