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. The United States was estimated to have produced 2.0% and consumed 1.6% of the world’s iron oreXI. AGGLOMERATION,Iron ore fines and concentrates are ground to suitable fineness generally 50-70% below 50 microns and mixed with some quantity of moisture and a suitable binder e.g., bentonite, lime etc and the mixture rolled in either a horizontal drum or an inclined disc.
