— Why Do We Mine So Much Iron Ore? Iron ore accounted for 93% of the metals mined in 2021, with 2.6 billion tonnes extracted from the ground. It's important to note that this is ore production, which is typically higher than metal production since metals are extracted and refined from ores.

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.
