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. Audio recording using magnetic acetate tape was developed in the 1930s. The German magnetophon utilized magnetite powder as the recording medium. Following World War II, 3MCompany continued work on the German design. In 1946, the 3M researchers found they could improve the magnetite-based tap

Magnetite an overview ScienceDirect Topics

In Mineral Processing Design and Operations (Second Edition), 2016. Magnetite [Fe 3 O 4]. Magnetite is often contaminated with titanium, forming minerals like ilmenite. The contaminated mineral shows an appreciable degree of magnetism. This property is made use of in the separation of ilmenite from other economical minerals such as rutile, monazite, zircon, leucoxene in Western Australia

Magnetite: Recording, Colourants,Fischer-Tropsch

Magnetite, iron(ii,iii) oxide, is a major ore of iron, and thus finds its primary use as a source of iron and for the production of steel. It is black, opaque and has the chemical formula Fe 3 O 4, possessing iron in oxidation states 3+ (ferric) and 2+ (ferrous).It is found widely distributed as large scale deposits, in igneous and metamorphic rock, in addition to in black sand and in fossils(1).

Difference Between Magnetite and Hematite Definition

Jan 31, 2018· Magnetite is an iron ore where iron can be found in the form of Fe 3 O 4. Magnetite is ferromagnetic, which means, magnetite particles are attracted to an external magnetic field; magnetite particles can act like tiny magnets when magnetized. Magnetite is ferromagnetic since it has both Fe 2+ and Fe 3+ ions that have many unpaired electrons

Magnet Manufacturing Process How Are Magnets Made

Magnetic Stabilization & Calibration. In some instances magnets will require stabilization or calibration. Stabilization is a process of pre-treating the magnets, in or out of an assembly, so that subsequent use will not result in additional loss of flux output. Calibration is performed to narrow the performance output range of a group of magnets.
