Earth's most important iron ore deposits are found in sedimentary rocks. They formed from chemical reactions that combined iron and oxygen in marine and fresh waters. The two most important minerals in these deposits are iron oxides: hematite (Fe2O3) and magnetite (Fe3O4). These iron ores have been …
This ore could further be smelted into ingots, or combined with iron ore to create steel. Corundum was used by blacksmiths to forge arms and armor in the Nordic style during the mid-Second Era, and was widely available. Steel plate armor can be made by adding iron to molten corundum. The resulting alloy is stronger than either metal by itself.Web
The most common iron-containing ore is haematite, but iron is found widely distributed in other minerals such as magnetite and taconite. Commercially, iron is produced in a blast furnace by heating haematite or magnetite with coke (carbon) and limestone (calcium carbonate). This forms pig iron, which contains about 3% carbon and other ...Web
