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.Iron Ore Crusher Plant, Iron Ore Crushing And Screening,,Iron ore is an important raw material of steel producers.After crushing, grinding, magnetic separation, flotation, re-election and other procedures,natural minerals,1.Crushing and sieving. Large iron ore is sent to the jaw crusher or mobile jaw crusher for coarse crushing by the vibrating feeder.Iron Ore Processing,Crushing,Grinding Plant Machine,Iron ore is the key raw material for steel production enterprises. Generally, iron ore with a grade of less than 50% needs to be processed before smelting and utilization. After crushing, grinding, magnetic separation, flotation, and gravity separation, etc., iron is gradually selected from the natural iron ore.
