Mauritanian iron ore powder (OM) has advantages of high iron grade, low aluminum content, and low loss on ignition, which can be used as a new mineral to replace low alumina limonite that has been exhausted in Australia. However, it will have a certain negative impact on sintering because of its high SiO2 content. The mechanism of SiO2 content affecting the sintering behavior was first studied ...

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 (Fe 3 O 4) and hematite (Fe 2 O 3 ). Iron ore is the source of primary iron for the world's iron and steel industries.
