Magnetite is an important ore of iron. Well formed crystals are popular among mineral collectors, and the magnetic Lodestone variety is frequently sold in hobby shops to amateur collectors. Magnetite is also of significant interest to the science community due to its strong magnetic properties.

Magnetite, also called lodestone, or magnetic iron ore, iron oxide mineral (FeFe 2 O 4, or Fe 3 O 4) that is the chief member of one of the series of the spinel (q.v.) group.Minerals in this series form black to brownish, metallic, moderately hard octahedrons and masses in igneous and metamorphic rocks and in granite pegmatites, stony meteorites, and high-temperature sulfide veins.
The most common form of Magnesite is white, microcrystalline, porous masses that are dull in luster, and have the appearance of unglazed porcelain.Because they are porous, they adhere to the tongue when licked. An interesting Magnesite occurrence is in Brumado, Brazil, where a deposit of clear, well formed, rhombohedrons similar to Iceland Spar Calcite found.
01/05/2020 Magnetite is a type of iron oxide with natural magnetic properties. In fact, it is the most magnetic naturally occurring mineral on Earth and was once used in compasses. Its chemical name is ferrous-ferric oxide, and its chemical formula is Fe 3 O 4.. Magnetite was used by ancient civilizations to magnetize compass needles.

Magnetite is rock mineral and one of the most important iron ore minerals with chemical formula is iron(II,III) oxide, Fe2+Fe3+2O4 .It also as the name magnetic minerals to attracted to a magnet. It is the most magnetic natural occuring minerals in the World. Small grains of magnetite occur in almost all igneous and metamorphic rocks. Name: An ancient term, possibly an allusion to the locality ...
Jacobsite-Magnetite Series. Magnesioferrite-Magnetite Series. Magnetite is an important iron ore, along with hematite. Nanoinclusions of magnetite crystals cause the iridescence of Rainbow obsidian (Nadin, 2007). Extremely thin layers of 200-nm octahedral crystals of magnetite give some basalt surfaces an iridescent sheen (Nadin, 2007).

Mineral name: Magnetite:. Chemical Composition: Fe 2 +Fe 3 + 2 O 4 Color: Black Streak: Black Hardness: 6 Cleavage: There is no cleavage. Magnetite may show some parting, which is a break along structural planes and is parallel to a possible face, just like cleavage.. Fracture: Magnetite has a Sub-Conchoidal Fracture, meaning it’s smooth with irregular rounded corners.

Magnetite. Strongly magnetic, this mineral is also known as “lodestone”. It is a common accessory mineral and can be found in banded iron formations. It is named for the locality Magnesia, Greece. A fable ascribes its name to a shepherd named Magnes, who first discovered the mineral on Mount Ida after noticing that the nails of his shoes and the iron ferrule of his staff adhered to the ...
05/12/2020 It is the most highly magnetic naturally occurring mineral, and the variety known as lodestone was the basis for the first crude magnetic compasses. Today, there are many uses of magnetite, such as for abrasives and coatings. Magnetite is a source of iron ore which is commonly used in the production of steel. Several minerals serve as sources of iron ore, and magnetite is one
In the field magnetite is one of the most easily found of all minerals because it is magnetic and is attracted to a magnet; some of this mineral possess weak magnetism itself, so it is called lodestone. The ancients were aware of this, and used it to make the first primitive compasses from magnetite carvings many of which looked like spoons whose handle pointed north. To prospector the first ...

The Magnetic Minerals are few, but the property is important because of this fact. Once a specimen is established as magnetic, identification becomes a rather routine exercise. The mineral magnetite is named after this characteristic. Magnetism occurs (most often) when there is an imbalance in the structural arrangement of the iron ions. Iron is found in two principle ionic states called ...
Magnetite, a ferrimagnetic mineral with chemical formula Fe3O4, one of several iron oxides, is one of the more common meteor-wrongs. Magnetite displays a black exterior and magnetic properties. magnetite Magnetite can be a found in a meteorite's crust. When a meteor enters the earth's atmosphere the rock's surface is ablated by ultra high temperatures. Before it hits the ground, the
