Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel—98% of the mined iron ore is used to make steel. Indeed, it has been argued that iron ore is "more integral to the global economy than any other commodity, except perhaps oil".

The iron proportion is (2 x 55.847)/159.691 = 0.6994. The reciprocal is 1.430, so you can either divide by 1.430 or multiply by 0.6994 to get the weight of iron in iron oxide. Note however, iron oxide is rarely pure Fe2O3, there are usually other oxide species and hydroxides present.
It reacted with oxygen, and generated carbon monoxide, which reduced the iron ore to iron metal. The liquefied slag separated from the ore, and was removed through the tapping arch of the furnace wall. In addition, the flux (metallurgy) (purifying agent), the charcoal ash and the furnace lining contributed to the composition of the slag.

The iron-ore concentrates containing different proportions of magnetite, goethite and hematite were obtained in a pilot-plant using the ROM ore. Typical chemical analysis are: Fe total = 63-68%; FeO = 0.2 - 4.7%; SiO 2 = 0.9-1.6% and Al 2 O 3 = 0.2-0.3 %. Total and ferrous iron were determined by titration with potassium dichromate, whereas the ...
2.1.1. FeO sinter The FeO content is an important control parameter in the sinter plant. When the chemical composition of an ore mix is fixed, FeO can provide an indication of sintering conditions, in particular the coke rate . A 2% increase in the FeO content in sinter has been found to lower (improve) the RDI by 8 points. However, a
In some ore Fe is partially replaced by Mg as (Fe, Mg) Cr2O4. The ore may have Fe in other form besides being present in the spinel. An accurate determination of FeO content is extremely important in chromite ores and refractories made with them.
process in which a sample is first analyzed for total iron expressed as FerO.. This is normally followed by a sepa-rate dissolution to directly determine the sample's FeO content. The manner in which a sample is dissolved dictates the valence of iron in the final solution used for total iron analysis. The two most common techniques employed in
Sep 10, 2018 (Heraldkeeper via COMTEX) -- Iron Ore Market 2018. Iron ores are rocks and minerals from which metallic iron can be economically extracted.
