Hematite | Fe2O3 - PubChem

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.

Replacement of magnetite by hematite in hydrothermal ...

1. Introduction. The replacement of magnetite by hematite is commonly observed in various geologic systems, especially in banded iron formations (BIF), iron oxide copper-gold deposits, and iron skarn deposits (Angerer et al., 2012; Franchini et al., 2000; Ehrig et al., 2021).The transformation of magnetite to hematite was attributed to an oxidizing reaction, generally
