The common ores of iron are both iron oxides, and these can be reduced to iron by heating them with carbon in the form of coke. Coke is produced by heating coal in the absence of air. Coke is cheap and provides both the reducing agent for the reaction and also the heat source - as you will see below. Iron ores

How steel is made. First, the raw materials, either iron ore or scrap iron (depending on the process), are converted into molten steel. The ore-based process uses a blast furnace or smelter and the scrap-based process uses an electric arc furnace. Next, the molten steel is poured and solidified in a continuous caster.

Most primary production occurs through the blast furnace-basic oxygen furnace (BF-BOF) route, though a smaller amount of primary steel is produced from direct reduction of iron (DRI) followed by processing in an electric arc furnace (EAF). Most secondary production, which is less energy intensive, occurs in an EAF.

To produce iron, they slowly burned iron ore with wood in a clay-lined oven. The iron separated from the surrounding rock but never quite melted. Instead, it formed a crusty slag which was removed by hammering. This repeated heating and hammering process mixed oxygen with the iron oxide to produce iron, and removed the carbon from the metal.
