Ironmaking 101 From Ore to Iron with Smelting and Direct

Oct 17, 2017 · Smelting Reduction. The reduced iron along with coal and lime is fed to a gasifier-melter, which completes the reduction process and produces pig iron or hot metal of the same quality as a blast furnace. The reducing gases generated by the gasifier-melter are recycled to reduce the iron ore in the pre-reduction step.
