Iron ore - Wikipedia

Iron ore Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel —98% of the mined iron ore is used to make steel Indeed, it has been argued that iron ore is "more integral to the global economy than any other commodity, except perhaps oil"Iron Ore Processing for the Blast Furnace,Each primary mill contains several 4" steel balls that grind the ore as the mills turn the ore is reduced to 3/4" or less, it moves out of the mill in a slurry solution discharge is screened at 1/4" on trommel screens attached to the mill process of separating the iron from the non-iron materialHow iron is made - material, manufacture, making, history ,
