3. Mill Scale Mill scale is a magnetic material consisting of iron in a typical range of 93-95%. Hence, the chemical composition of mill scale is similar to hematite magnetite or wstite. The X-ray diffraction analysis showed that the mineralogical phases in mill scale could be Hematite Fe2O3, Magnetite Fe3O4 and Wstite, FeO. The chemical analysis of iron ore fines, fluxes, bentonite, and mill scale used in the study is shown in Table 1. The size fraction of as received iron ore fines was 24% above 6 mm and 36% below 1 mm and mill scale size was 3% above 6 mm and 60% below 1 mm. Received raw materials were ground in ball mill at 6 kg/ batch for varying time of retention.
