Magnetite ore, long the leading source of domestic iron supply in North America, Europe and China, is now increasingly relevant across the globe. The perception that magnetite ore is an inferior substitute to hematite ore is now firmly changing. As easily accessibly, economic hematite deposits become rarer, magnetite ore will continue to emerge as an
Magnetite, with chemical formula Fe3O4, is an iron ore found in igneous, metamorphic rocks. It belongs in the same group of iron ore as the hematite or the maghemite. Magnetite is a chemical compound of iron and oxygen and therefore an oxide. Magnitite is physically rather stable, as it is a octahedral crystal.
2018-10-20Use of Magnetite as an Ore of Iron. Most of the iron ore mined today is a banded sedimentary rock known as taconite that contains a mixture of magnetite, hematite, and chert. Once considered a waste material, taconite became an important ore after higher grade deposits were depleted. Todays commercial taconites contain 25 to 30 iron by weight.
Magnetite, ideal formula Fe 3 O 4, is an intriguing mineral, and not only because it is magnetic.The formula could be written as Fe 2 Fe 3 2O 4, which more precisely designates one of its peculiarities.It contains both ferrous Fe 2 and ferric Fe 3 ions implying synthesis, growth, and stability within an environment where oxidized and reduced states of iron are present and maintained.

Magnetite is a major source of iron. Banded iron formations are precambrian metasedimentary rocks where the iron-bearing phase is usually either magnetite or hematite. Very rich magnetitic iron ore is in Kiruna northern Sweden although the formation details are not clear it is not banded iron formation.
2018-11-27Iron is the worlds most commonly used metal - steel, of which iron ore is the key ingredient, representing almost 95 of all metal used per year. It is used primarily in structural engineering applications and in maritime purposes, automobiles, and general industrial applications machinery.
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 colour from dark grey, bright yellow, deep purple, to rusty red. The iron itself is usually found in the form of magnetite Fe 3 O 4, hematite Fe 2 O 3, goethite, limonite or siderite.Hematite is also known as natural ore.
