Crushing Circuit

A. Jankovic, in Iron Ore, 2015. 8.2 Iron ore crushing and screening. Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel. About 98% of the mined iron ore is used to make steel either by the blast furnace—basic oxygen furnace (BF-BOF) route—or through the electric arc furnace (EAF) route.
