To make steel, metcoal is heated at around 1100 degrees C to remove water and other chemicals. This is done without the presence of oxygen. The result is a lump of near-pure carbon which is called coke. The coke is fed into a blast furnace along with 'raw' iron ore and some other minerals called fluxes. This produces pig iron.
