Types of Iron Ore: Hematite vs. Magnetite MineListings

Jan 04, 2016 With the chemical formula Fe3O4, magnetite ore has much lower iron content than hematite ore. That means it has to be concentrated before it can be used to produce steel. However, the ore’s magnetic properties help separate magnetite ore from rock during concentration.

Difference Between Magnetite and Hematite Definition

Jan 31, 2018 Magnetite and hematite are two forms of iron ores from which iron can be extracted. Magnetite contains iron in the form of Fe 3 O 4. Hematite contains iron in the form of Fe 2 O 3. The main difference between magnetite and hematite is that magnetite is ferromagnetic whereas hematite is

Types of Iron Ore: The Difference Between Hematite vs

Magnetite ore’s most distinctive property is its magnetism. It is the most magnetic mineral in the world. Additionally, obtaining iron from hematite ore can produce a great deal of carbon emissions, and the process for magnetite is much less harmful. The product from magnetite ore is also of higher quality than from hematite ore.

Why is hematite used over magnetite? Magnetite has more

Magnetite has higher iron content than hematite. But hematite ore usually contains large concentrations of hematite; magnetite ore, low concentrations of magnetite. The ore has lower iron content, typically between 25% and 40% Fe. This ore is unsuitable for steel making, and it must be concentrated before it can be used to produce steel.

Iron ore Wikipedia

Ores containing very high quantities of hematite or magnetite (greater than about 60% 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—98% of the mined iron ore is used to make steel.

University of Minnesota’s Mineral Pages: Hematite

Regardless of its setting, hematite is usually found with other iron-bearing minerals, especially magnetite, goethite and siderite. In Early Proterozoic (2.5 to 1.6 billion year ago) iron ore deposits, layers of hematite and other iron oxides alternate with bands of chert (microcrystalline quartz) to form distinctively layered deposits known as

Magnetite ~ Hudson Valley Geologist

Nov 06, 2010 Now we can discuss magnetite. Magnetite (Fe 3 O 4) is also a common ore of iron but, unlike hematite, it contains both oxidation states of iron so can be called iron(II,III) oxide or ferrous-ferric oxide and the formula can also be written as FeO • Fe 2 O 3. where the FeO is ferrous iron (Fe 2+) and the Fe 2 O 3 is ferric iron (Fe 3+).
