Iron Ore is a Metal Ore found in abundance in the Caustic Biome and Oil Biome. It is used as a construction material and can be refined into pure Iron. Iron Ore shares many properties with other metal ores, but lacks a defining feature that provides it an edge, such as the decor bonus on Copper Ore or the thermal overheat bonus of Gold Amalgam. It is, however, by far the most …

Hydrogen is used to reduce Fe2O3 to metallic iron according to the following reaction: Fe2O3 + 3H2 -> 2Fe + 3H2O. The water is condensed and the unreacted hydrogen is recycled as in the figure below. The fresh feed contains a mixture of hydrogen and CO2, with the CO2 being 1% of the feed (mole percent).
