The arc of the trade (rich hematite exhausted → low-grade magnetite beneficiated → product engineered for the furnace) is the exact arc [[In_situ_resource_utilization|ISRU]] planners assume for regolith and asteroid feedstock: *all* extraterrestrial ore is low-grade ore. Metallic asteroids like 16 Psyche invert the story — ore that skipped geology and arrived pre-refined. !300 *In motion: load-out at the ore dock — the shipped product leaving the Range.

Iron ores are rocks and minerals from which metallic iron can be economically extracted — chiefly the oxides hematite (Fe₂O₃, 69.9% iron) and magnetite (Fe₃O₄, 72.4% iron). Most of the world's minable iron sits in banded iron formations: chemically precipitated seafloor sediments, iron minerals interlayered with chert, laid down mostly between about 2.5 and 1.8 billion years ago as photosynthetic oxygen swept the oceans' dissolved iron out of solution. A banded iron formation is, quite literally, a fossil of the Great Oxidation Event — which is why the same rock type is a mapping target on Mars. Australia and Brazil dominate the export trade; China dominates consumption. Ore ships as lump, as sinter feed, or — the Minnesota specialty — as fired pellets upgraded from low-grade rock, increasingly including DR-grade pellets destined for direct-reduction ironmaking rather than blast furnaces. ## Wikipedia : Wikitube **Strict pair:** [Wikipedia](https://en.wikipedia.org/wiki/Iron_ore) : [Wikitube](https://en.wikitube.io/wiki/Iron_ore) ## Previous hub tags Tree parent: [[Oxygen]].
