3 Iron Ores are obtained by mining Iron Ore Veins. Can be purchased at all levels. 1 Iron Ingot is obtained by smelting 1 Iron Ore (this is the only case where only one ore is required to make an ingot). Can be purchased at all levels. 1 Steel Ingot is obtained by smelting 1 Iron Ore and 1 Corundum Ore.
How steel is made - a summary of a Blast Furnace
To make steel, iron ore is first mined from the ground. It is then smelted in blast furnaces where the impurities are removed and carbon is added. In fact, a very simple definition of steel is "iron alloyed with carbon, usually less than 1%." The following text is taken

2020/1/14· Ironmaking, the first step in making steel, involves the raw inputs of iron ore, coke, and lime being melted in a blast furnace. The resulting molten iron—also referred to as hot metal—still contains 4-4.5% carbon and other impurities that make it brittle.
How much iron ore is needed for 1 tonne of steel rebar? …
Steel is around 95% iron. The amount of iron ore it takes to produce 1 ton of steel is dependent on the iron content of your iron ore. The most heavily referenced iron ore indices (TSI, Platts) take to a 62/63% iron ore standard. You do the math.
