Production of Iron Oxide Pigments from Mill Scale Waste

Mill scale, a waste byproduct from steel manufacturing, presents environmental challenges but offers potential for resource recovery. This study investigates the suitability of mill scale from the skew rolling process of steel ball production for use in iron oxide pigment manufacturing. The collected mill scale was dried, ground, and analyzed using Spark Emission Spectroscopy (SES), X-Ray Fluorescence (XRF), and X-Ray Diffraction (XRD). Results showed that ۸۵.۷ wt% of the sample consisted of iron oxides, primarily Fe۲O۳, with additional oxides of Si, Mn, and Cr. The presence of trivalent iron oxide indicates potential for pigment applications. These findings support the use of steel industry waste as a sustainable raw material, promoting environmental conservation and circular economy practices.
