4 Iron Ore Consumption. Iron ore is used directly in the steelmaking process in the blast furnace in the form of lump, pellet, and fines (see Fig. 5 ). (Fines are converted to sinter feed in a sinter plant.) Iron ore pellets are also used in the production of DRI and HBI. Sign in to download full-size image.
