The following Iron Ore specifications guide contains the primary specifications and methodologies for Platts Iron Ore assessments throughout the world. These are the timestamps used for Platts iron ore assessments. Data reported at or after these timestamps is not considered in the assessment process.
Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe3O4) and hematite (Fe2O3). Iron ore is the source of primary iron for the world's iron and steel industries.
FeO plus Fe2O3 gives Fe3O4. This is a compound with equal amounts of iron +3 and +2. Why it does this others can explain. Or if you calculate it it comes to 2 and 2/3, which is not a very sensible answer as it is a non integer value!
