Iron Ore Processing for the Blast Furnace

processing facility located on the Mesabi Iron Range of Minnesota. Creating steel from low-grade iron ore requires a long process of mining, crushing, separating . separators. Once again, the magnetic separators grab the iron and discard the silica and sand. Thus, the ore is. "concentrated" by removing the waste materials.

Iron ore - Wikipedia

DSO deposits are typically rarer than the magnetite-bearing BIF or other rocks which form its main source or protolith rock, but are considerably cheaper to mine and process as they require less beneficiation due to the higher iron content. However, DSO ores can contain significantly higher concentrations of penalty.
