Mill scale Wikipedia
Rolling Mill scale is a complex oxide that contains around 70% iron with traces of nonferrous metals and alkaline compounds. The reduced iron powder may be obtained by converting the mill scale into a single highest oxide i.e. hematite (Fe2O3) and its reduction with hydrogen.

Semi steel products are often first
What exactly is Mill Scale and what is done about it
In a rolling mill where the steel will be stretched and squished the mill scale will first be removed mostly by water jets, or by sand blasting in some shops or by vibrating rolls in others and the mill scale will fall into a pit below the equipment where it will also be joined by rolling mill lubricants and bearing oils and water. From thereReferences Danieli Environment,The WTP is characterized by the most uptodate technology developed by Danieli for the steel sector, including: > Zero Scale Pit, to reduce the excavation and civil works for the scale pit and simplify scale removal > DanFilters, the patented, highspeed sand filters designed in our research center to reduce the footprint.

127· The mill scale is washed away from steel surfaces and flushed into flumes underneath the hotrolling lines by a large amount of contact water, which includes descaling water and cooling water.12.5 Iron And Steel Production US EPA,12.5.2.4 Steelmaking The most significant emissions from the BOF process occur during the oxygen blow period.The predominant compounds emitted are iron oxides, although heavy metals and fluorides are usuallypresent. Charging emissions will vary with the quality and quantity of scrap metal charged to thefurnace and with the pour rate.
What exactly is Mill Scale and what is done about it
Steel mills descale sheet and plate by passage through scalebreaker rolls, which flexes the metal enough to fracture the scale. This allows pickling acid (HCl) to attack the more soluble (partially transformed) inner wüstite layer.
