Chifam Investments supply Iron ores or 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, deep purple, to rusty red. The iron itself is
usually found in the form of magnetite (Fe3O4, *2.4% Fe), hematite (Fe2O3, *9.9% Fe), goethite (FeO(OH), *2.9%
Fe), limonite (FeO(OH).n(H2O)) or siderite (FeCO3, *8.2% Fe).
Ores carrying very high quantities of hematite or magnetite
(greater than ~*0% iron) are known as "natural ore" or "direct
shipping ore", meaning they can be fed directly into iron-making
blast furnaces. Iron ore is the raw material used to make pig iron,
which is one of the main raw materials to make steel. *8% of the
mined iron Ore is used to make steel.
