netite than a magnetotactic bacterium. The amount of magnetite produced is primarily limited by the amount of Fe(III) present in the culture that is available for reduction by cells (Frankel 1987). Culture conditions may also play a role in the size and the degree of crystallinity of magnetite grains produced by Fe(III)-reducing bacteria.

Iron is the found in abundance in minerals, but the process of extracting iron from different minerals varies in cost depending on the mineral. It is least costly to extract the iron from oxide minerals like hematite (Fe 2 O 3), magnetite (Fe 3 O 4), or limonite [Fe(OH)].

Before modern mineral analysis, the name "limonite" was given to many of the yellowish to yellowish brown iron oxides produced during the weathering of iron-bearing rocks or deposited as bog, lake, and shallow marine sediments.

When magnetite is added to a concrete mix, it produces heavy concrete, which is twice as dense as standard concrete. Heavy concrete is widely used in buildings that require protection from radiation, such as nuclear power plants, X …

Magnetite ores occur in large bodies in almost all countries, and on account of the high iron tenor of the pure mineral, and the ease with which it is concentrated, its treatment forms one of the most important fields of magnetic separation.

Magnetite is a relatively abundant mineral, for it is a minor constituent of many different types of rocks. Where it is sparser disseminated as large grains in some rocks, the characteristic octahedral crystal form of magnetite is often identifiable.

As a member of the spinel group, it can form solid solutions with similarly structured minerals, including ulvospinel (Fe 2 TiO 4), hercynite (FeAl 2 O 4) and chromite (FeCr 2 O 4). Titanomagnetite, also known as titaniferous magnetite, is a solid solution between magnetite and ulvospinel that crystallizes in many mafic igneous rocks.

Magnetite is a rock mineral and one of the main iron ores, with the chemical formula Fe 3 O 4. It is one of the oxides of iron, and is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself.

Magnetite is best known for its property of being strongly attracted to magnets. Some forms of Magnetite from specific localities are in fact themselves magnets. Commonly known as Lodestone, this magnetic form of Magnetite is the only mineral that is a …

Normal magnetite is attracted to a magnet, but some specimens are automagnetized and have the ability to attract small pieces of iron, small pieces of magnetite, and other magnetic objects. This form of magnetite, known as "lodestone," was man's first encounter with the property of magnetism.

Magnetite is one of the few naturally occurring magnetic materials, and as it forms, its magnetic poles align with those of the Earth. Once formed, however, the magnetite's magnetic alignment does not change, even if Earth's magnetic field changes.

Magnetite is a black, opaque, magnetic mineral that leaves a black streak when rubbed across a hard rough surface. It is one of the most abundant metal oxides, and its crystal structure contains both the ferrous (Fe+2) and ferric (Fe+3) forms of iron ions.

By comparison, magnetite ore typically has a much lower iron content when mined of between 25% and 40% Fe and in this form is unsuitable for steel making. The main iron mineral in magnetite ore is the ferrous iron oxide magnetite (Fe 3 O 4).
