iron ore recovery from hematite

Low-temperature (< 1300 °C) iron ore sinter is an agglomerate of unmelted and partially melted nuclei particles (+ 1 mm) and a matrix bonding phase produced from the melting of fine ore (− 1 mm) and flux particles, with the majority of melt formation occurring in the granule adhering fines layer. The majority of nuclei are hematitic, but they can also be any other unreacted particles such as flux or aluminosilicate …

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. It is therefore essential for the production of steel, which in turn is essential to maintain a strong industrial …
