iron processing iron processing Ores: Iron ores occur in igneous, metamorphic (transformed), or sedimentary rocks in a variety of geologic environments. Most are sedimentary, but many have been changed by weathering, and so their precise origin is difficult to determine. The most widely distributed ironbearing minerals are oxides, and iron ores consist mainly of hematite (Fe2O3), which is ...

Though taconite was identified as an ironbearing rock on the Iron Ranges of northern Minnesota long before the 1950s, it wasn't until then that it was profitably extracted, processed, and shipped to steel mills on the Great Lakes. As natural ore reserves were diminished, taconite became an alternative source of iron that allowed the Iron Range to continue mining operations in a changing ...
Iron Ore Statistics and Information. 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 ...
