Iron ore - Wikipedia

This stockpile of iron ore pellets will be used in steel production. Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (Fe 3 O 4, 72.4% Fe), hematite (Fe

Iron ore crushing is now mostly done in iron ore processing workshops and in self-braking and semi-self-breaking Asian countries instead of classical Asia (rod-pellet). In autochthonous Asians, the extracted stones enter autochthonous Asia directly after the first stage of crushing, and the coarse grains crush other particles as they break down.
