Iron ores are rocks and minerals from which metallic iron can be extracted. There are four main types of iron ore deposit: massive hematite, which is the most commonly mined, magnetite, titanomagnetite, and pisolitic ironstone. These ores vary in colour from dark grey, bright yellow, or deep purple to rusty red.

Gray iron has a gray fracture surface with finely faced structure. A large Si content (2-3 wt. %) promotes C flakes precipitation rather than carbide 3. Ductile iron: small addition (0.05 wt..%) of Mg to gray iron changes the flake C microstructure to spheroidal that increases (by factor ~20) steel ductility 4.
