as iron ore, coal, limestone and steel scrap. About 75% of steel is produced using the BF-BOF route. First, iron ores are reduced to iron, also called hot metal or pig iron. Then the iron is converted to steel in the BOF. After casting and rolling and/or coating, the steel is delivered as strip, plate, sections or bars.
Figure 1: Steelmaking byproducts for blast furnace (BF), basic oxygen furnace (BOF) and electric arc furnace (EAF) processes. Source: World Steel Association (worldsteel) The first step in the production of steel or cast iron alloys is the reduction of iron ore—which contains iron oxide and gangue or mineral impurities—to unrefined, …

Iron Ore is an early-game ore that generates upon world creation on the Surface, as well as in the Underground and Cavern layers. Its primary use is in crafting Iron Bars, which can then be used to craft the Iron tier of tools, weapons, and armor, as well as Buckets, Chains, and several other items. The equivalent of Iron Ore is Lead Ore, which will sometimes …
What is Iron Ore used for? The vast majority of iron ore is used to produce iron which is in turn used to produce steel. 98% of the iron ore mined today is used for steel production. This includes staples, cars, and steel beams used in the construction of buildings and just about anything else where iron and steel are needed.
What is Iron Ore Used For? Iron ore is almost entirely used for making steel (98% of production), which is then used as a material in various industries across the economy, including [2]: Energy Infrastructure – Without iron ore, we could not make the steel required to manufacture wind turbines, electricity pylons, hydro dams, nuclear …
