Magnetite is black or brownish-black with a metallic luster, has a Mohs hardness of 5–6 and leaves a black streak. [7] Small grains of magnetite are very common in igneous and metamorphic rocks. [11] The chemical IUPAC name is iron (II,III) oxide and the common chemical name is ferrous-ferric oxide. [12] … See more Magnetite is a mineral and one of the main iron ores, with the chemical formula Fe Fe 2O4. 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. … See more Biomagnetism is usually related to the presence of biogenic crystals of magnetite, which occur widely in organisms. These organisms range from magnetotactic bacteria (e.g., Magnetospirillum magnetotacticum) to animals, including humans, where … See more Due to its high iron content, magnetite has long been a major iron ore. It is reduced in blast furnaces to pig iron or sponge iron for conversion to steel. Magnetic recording Audio recording using magnetic acetate tape was … See more In addition to igneous rocks, magnetite also occurs in sedimentary rocks, including banded iron formations and in lake and marine sediments as both detrital grains and as magnetofossils. Magnetite nanoparticles are also thought to form in soils, where they … See more Magnetite is sometimes found in large quantities in beach sand. Such black sands (mineral sands or iron sands) are found in various places, such as Lung Kwu Tan of Hong Kong; California, United States; and the west coast of the North Island of New Zealand. … See more Magnetene is a 2 dimensional flat sheet of magnetite noted for its ultra-low-friction behavior.
