Ore Grinding Mills - Mineral Processing & Metallurgy
Ball mills have shells of cast iron or steel plates and are carried on hollow trunnions. Ore is fed through a scoop, drum-type, or combination feeder at one end and is discharged from the opposite trunnion. Ball mills may be arbitrarily classified into two types, according to the method of pulp discharge.

Iron and steel industry in the United States - Wikipedia
In an integrated steel mill, iron ore is reduced to metallic iron. In the US, this is done in blast furnaces. The direct-reduction method of producing iron from ore has not been used in the US since 2012. Some of the iron from the blast furnaces is converted to steel; today this is done in basic oxygen furnaces.
