Magnetite is a 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. It is the most magnetic of all the naturally occurring minerals on Earth. Naturally magnetized pieces of magnetite, called lodestone, will attract small pieces of ...

30-03-2018· 1 Introduction. Banded iron formations (BIFs) are Precambrian chemical sedimentary rocks, typically thin bedded or laminated, containing ≥15% Fe of sedimentary origin, which commonly but not necessarily contain layers of chert (James, 1954).The BIFs were chemically precipitated in the Precambrian ocean, from the Archaean to the Paleoproterozoic (3.8–1.8 Ga) but are conspicuously …
origion of banded magnetite quartz ore. Ore genesis, · Various theories of ore genesis explain how the various types of mineral deposits form within the Earth's crust. Ore-genesis theories vary depending on the mineral or commodity examined. Ore-genesis theories generally involve three components: source, transport or conduit, and trap.
