Hematite - Wikipedia
Hematite, also spelled as haematite, is a common iron oxide with the formula Fe 2 O 3 and is widespread in rocks and soils. Hematite crystallizes in the rhombohedral lattice system, and it has the same crystal structure as ilmenite and corundum.Hematite and ilmenite form a complete solid solution at temperatures above 950 °C (1,740 °F).. Hematite is colored black to steel or silver-gray ...

Magnetite Concentration Methods
The yellow crystals break away freely from the magnetic material. When the magnetite is in large pieces in the crude ore, or in large crystals, it is readily handled by cobbing; when the ore is massive, or when the magnetite and apatite crystals are small and intimately associated, finer crushing is necessary for the same degree of concentration.

Magnetite - Assignment Point
Applications of Magnetite. 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 biomineralization in the human brain.
· Magnetic property data indicate the crystals are in clumps of between 50 and 100 particles. Biogenic magnetite in the human brain may account for high-field saturation effects observed in the T1 and T2 values of magnetic resonance imaging and, perhaps, for a variety of biological effects of low-frequency magnetic fields.

Magnetite - Wikipedia
Magnetite or Lodestone... Want To Magnetically Attract What You Desire? Written By Liz Oakes. Magnetite is a potent stone for manifestation, helping you to attract what you most desire, including both desirable situations and people. Also called Lodestone, this form of the stone is naturally magnetic.
Magnetite is the primary oxide of iron found in meteorites (and thus presumably in asteroids). Thermite is a mixture of powdered magnetite and powdered aluminum. When ignited, the aluminum fuel burns using the magnetite as an oxidizer, resulting in much heat, aluminum oxide (corundum), and molten iron.

Trivia. Magnetite was renamed to Iron Ore but was then changed back to Magnetite shortly afterward.. In real life, Magnetite is often mined and used as a source of iron as an Iron Oxide Crystal.
MAGNETITE Mineral Facts & Information Page
Magnetite is one of the most ubiquitous minerals, occuring in a great variety of igneous, metamorphic and sedimentary rocks, typically as disseminated crystals or grains comprising less than one percent of their host rock. Most plutonic igneous rocks commonly contain magnetite as disseminated grains.
