Physical Observation of the Iron ore Fines During Reduction. Iron ore fine reduction depending on its density will likely reduce either in a topochemical reduction [136] or a complete uniform internal reduction mode [137]. Most dense iron ores typically exhibit a topochemical reduction mechanism and is shown in the following.
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.
