Sep 27, 2008· A chemical engineer determines the mass percent of iron in an ore sample by converting the Fe to Fe2+ in acid and then titrating the Fe2+ with MnO4. A g sample was dissolved in acid and then titrated with mL of M KMnO4. The balanced equation is given below. 8 H+(aq) + 5 Fe2+(aq) + MnO4(aq) 5 Fe3+(aq) + Mn2+(aq) + 4 H2O(l) Calculate the mass percent of iron in the ore.

4 Penalty Elements in Iron Ore Thermo Fisher Scientific
in iron ore and the coal used in the smelting process. At concentrations > 300 ppm, S causes brittleness in hot iron so the iron cannot be used in steel making. Phosphorous (P) can increase the hardness and strength of steel when present between 700 and 1200 ppm, yet the presence of P > 2000 ppm can make steel brittle at room temperature.

Use of Boron Compounds as Binders in Iron Ore Pelletization
In pelletizing, a mixture of iron ore, water and binder is rolled in a mechanical disc or drum to produce agglomerates (green balls or wet pellets). Green pellets then undergo a thermal process, which consists of three stages, namely drying (250 – 400oC), preheating (900 – 1100oC) and firing (1200 – 1300oC).

Iron and Steel Statistics and Information
The element iron (Fe) is one of the most abundant on earth, but it does not occur in nature in useful metallic form. Iron ore is the term applied to a natural ironbearing mineral in which the content of iron is sufficient to be commercially usable. Metallic iron, from which steel is derived, must be extracted from iron ore. By definition, steel is a combination of iron
