  • Iron removal by physical chemical way Lenntech

    Lenntech iron removal. Iron is one of the most abundant metals of the Earth's crust. It occurs naturally in water in soluble form as the ferrous iron (bivalent iron in dissolved form Fe 2+ or Fe(OH) +) or complexed form like the ferric iron (trivalent iron: Fe 3+ or precipitated as Fe(OH) 3).The occurrence of iron in water can also have an industrial origin mining, iron and steel industry

  • How Is Iron Extracted From the Earth? Reference

    Iron ores in the form of hematite (ferrous oxide) and magnetite are removed from the earth through mining. The use of heavy mining equipment is necessary to dig out large pits in an area with a large deposit of iron ore however, because iron does not occur naturally, it is necessary to use a blast furnace to separate or refine iron from the other substances in the iron ore.
