This evaluation method lacks comprehensive research on the characteristics of iron ore powder, especially the hightemperature physical and chemical characteristics reflected by iron ore powder in the sintering process. Therefore, it is difficult to reasonably select and utilize various iron ore powders [14, 15].

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.
