4 Penalty Elements in Iron Ore - Thermo Fisher Scientific

SULFUR. Sulfur (S) can be present as sulfides 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
