magnetic iron ore uses

  • 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. Audio recording using magnetic acetate tape was developed in the 1930s. The German magnetophon first utilized magnetite powder that BASF coated onto cellulose acetate before soon switching to gamma ferric oxide for its superior morphology. Following World War II, 3M Compan2021年3月24日  Introduction. Jump To. Depletion of the mineral ore base of high-grade quality and easily beneficiated iron ores has led to the need for improvement in the processing of low-grade and complex Mineral and Technological Features of Most processes rely on density differences to separate light minerals from heavier ones, so the ore is crushed and ground to release the ore minerals from the gangue.

  • Magnetite - American Chemical Society

    2020年6月15日  Magnetite’s greatest use is as an important iron ore for steel manufacture. Other applications are as a catalyst in the Haber process for making ammonia, as a pigment for paints and ceramics, and as Magnetite, iron oxide mineral (FeFe2O4, or Fe3O4) that is the chief member of one of the series of the spinel (q.v.) group. Minerals in this series form black to brownish, metallic, Magnetite Magnetic Properties, Iron Oxide, MagnetismUnlike the high-grade hematite ores which are easily processed into saleable iron products, through crushing, grinding or milling, concentration by screening, and/or using hydraulic Beneficiation of Magnetite Ores
