The remaining 2% of domestic iron ore was produced for non-steel end uses. Seven open-pit iron ore mines (each with associated concentration and pelletizing plants), and three iron metallic plants—one direct-reduced iron (DRI) plant and two hot-briquetted iron (HBI) plants— operated during the year to supply steelmaking raw materials.
