Experimental Studies on Reduction of Coarse Blue Dust for ...

05/02/2019  Blue dust is a high grade soft hematite ore fines containing more than 90% Fe2O3. This was termed as blue dust due to its characteristic luster and fineness. These iron ore fines are dumped at site due to transportation problem. The particle size of the blue dust lies in the micron range, it cannot be used directly in the blast furnace for iron making [1]. Huge occurances of powdery iron ore have been observed during the study of the Precambrian sedimentary iron ore
