Mill scale is very attractive industrial waste due to its richness in iron (about = 72% Fe). In this paper, the characterizations of mill scale were studied by different methods of analyses. The produced mill scale briquettes were reduced with hydrogen at varying temperatures, and the reduction kinetics was determined. Two models were applied and the energy of activation was calculated.
Mill Scale Uses and Applications. A discussion started in 2002 but continuing through 2019. 2002. Q. My company uses iron ore (magnetite) in its process. However, a large amount of mill scale has become available and we are looking at it as a substitute or supplement.

The mill scale contains high amounts of Fe and low amounts of silica and alumina. Thus, recycling it through the sintering process helps in the saving of raw materials like iron ore and limestone. This paper presents preliminary findings of a study that investigates the potential for recycling steel mill scale in the sintering process.
The mill scale is produced during the milling process from the sudden oxidization of the hot iron products. The main component of the mill scale is iron oxide (>95%) The mill scale can be used as: 1. Additive in the production of ceramic tiles and roofing 2. Additive in the cement industry 3. Catalyst in the recycling of batteries 4.
Nov 19, 2018· Mill scale consists of oxides of iron, above all, but also the metal alloys that are included in the steel of which the mill scale is formed. Chemically, the mill scale can be compared with iron ore and can frequently be used in similar applications, e.g. as a raw material on production of pig iron, ferrous alloys and cement.
