Nearly 35-40Kg of mill scale is produced for every ton of hot rolled steel [1]. Mill scale is reported to be used as raw material in sintering plants [2] and as briquette in steelmaking. [3- 5]. Apart from these scarce uses, most of the mill scale is dumped in landfills, which pose grave environmental hazard due to leaching of heavy metals in soil.

Under visual inspection, mill scale appears as a black metal powder made up of small particles, flake, and chips. Its physical state is solid and powdered. The bulk density of mill scale is in the range of 5.7 tons/cum while the specific gravity is 6.2. The melting point of mill scale is around 1370 deg C and the boiling point is around 2760 deg C.
Mill scale is formed on the outer surfaces of plates, sheets or profiles when they are being produced by rolling red hot iron or steel billets in rolling mills. Mill scale is composed of iron oxides mostly ferric and is bluish black in color. It is usually less than 1 mm (0.039 in) thick and initially adheres to the steel surface and protects ...

Only one mill scale recycling project was successfully implemented, to our knowledge. This was at a mill near Chicago, circa 1990. The proprietary process employed involved the use of surface chemistry modification together with heat and mechanical energy input in an aqueous environment to separate the oil from the mill scale.
The purpose of our paper is to assess the reuse potential of the steel mill scale for sustainable industrial applications. We have presented the experimental procedures for chemical and mineralogical characterizations. According to the results of the elementary chemical analysis, the steel mill scale contains the following predominant chemical elements: iron, aluminum, silicon, and magnesium.
The mill scale contains the three iron oxides. Their reduction with hydrogen. occurs according to three basic reactions: F e 3 O 4 + 4H 2 = 3F e + 4H 2 O, (1) F e 2 3 + 3H 2 = 2F e + 3H 2 O, (2) F ...
