purpose of limestone in iron ore pellets in Oman
Iron Ore Pellets
The main iron component is magnetite, black magnetic iron ore, = Fe3O4, some hematite (red iron oxide ore, Fe2O3). Those ores are found in the Mesabi iron range of Minnesota and the Marquette iron deposits in Michigan. The ore has to be concentrated before it is usable in a blast furnace.

In the iron ore pellets, iron oxide completely reduced at 850 °C and 700 °C to metallic iron with some silica peak was observed. In the BR and self-hardened BR-CaO pellets reduced at 850 °C, majority of all iron oxide is reduced. However, at 700 °C, it was converted to a mixture of metallic iron, magnetite and minor brownmillerite.
