Magnetite Wikipedia

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 developed in the 1930s. The German magnetophon utilized magnetite powder as the recording medium.

Vanadium processing, preparation of the metal for use in various products.. Vanadium (V) is a grayish silver metal whose crystal structure is a bodycentred cubic (bcc) lattice, with a melting point of 1,926° C (3,499° F). The metal is used principally as an alloying addition to highstrength lowalloy (HSLA) steels and, to a lesser extent, in tool steels and iron and steel castings.

How Is Iron Extracted From the Earth? Reference

Iron ores in the form of hematite (ferrous oxide) and magnetite are removed from the earth through mining. The use of heavy mining equipment is necessary to dig out large pits in an area with a large deposit of iron ore however, because iron does not occur naturally, it is necessary to use a blast furnace to separate or refine iron from the other substances in the iron ore.

Benson Mines Wikipedia

The ability to concentrate "nonmagnetite ores by gravity processes" at Benson mines ensured its economic expansion because these processes enabled lower grade iron ore to be used in steelmaking. In 1952, a gravity plant was built, which allowed nonmagnetic ore to be processed on site. Ore was extracted using open pit mining methods.
