Mill scale separation. Process C. Mill scale forms during steel production. It is a thin oxide coating that is created when steel is hot-rolled. When the steel is cooled down with water during the rolling process, the mill scale breaks off. The cooling water is re-used over and over again, which means that mill scale and oil residue particles

Generally, 70–100% mill scale containing high iron is being recycled through either briquetting or sintering route with out any difficulties. In some cases, de-oiling of the material is required.
Mill scale is one of waste materials which is produced as a result of hot rolling of steel in all steel companies. On the other hand, mill scale is considered a rich iron source with minimum impurities. This work aims at conversion of mill scale by adjusting smelting processes to produce different valuable products. The smelting processes were carried out using carbothermic reduction in a
Iron Platform, January 2014 Page 1 1. Background . This document does not intend to provide a full description of the uses of Mill scale (ferrous metal) [EC: 266-007-8] as such, but may be used as additional information and explanations on mill scale uses as reported in the REACH registration dossier.
Aug 30, 2019· Mill scale size was first reduced by means of ring mill process down to 150 mesh. The fraction of raw materials (mill scale and carbon) used in this study was calculated based on Gibbs free energy method leading to the optimal formation of Fe metal. From the calculation, the mixing ratio of mill scale to carbon (CCC) is found as 6:1 (in wt%).

However, the finer fractions of mill scale contain too much oil for recycle to a sinter plant, and are known to cause a blue haze in the air discharge from sintering operations when the oil level is excessive. Only one mill scale recycling project was successfully implemented, to our knowledge. This was at a mill near Chicago, circa 1990.
The current invention relates to a method of manufacturing iron oxide pigments from mill scale. The mill scale is mixed with alien iron oxide and the resultant mixture is heated to a temperature of 200° C. to 900° C. in an oxidizing atmosphere to produce iron oxide pigment which can be black, brown or red. The alien iron oxide used and the iron oxide pigment produced are predominantly Fe 2 O
