Comminution and classification technologies of iron ore
Iron ore crushing and screening. Iron ore 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 electrical arc furnace (EAF) route. The majority of world crude steel is made from the BF-BOF route.
