· 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 (BFBOF) route—or through the electric arc furnace (EAF) route. The majority of world crude steel is made from the BFBOF route. Ores carrying very ...
This separation technique can be useful in mining iron as it is attracted to a magnet.
