  • Magnetic Separation and Iron Ore Beneficiation – IspatGuru

    Oct 04, 2018· Magnetic Separation and Iron Ore Beneficiation Magnetic separation is an old technique for the concentration of iron ores and for the removal of tramp iron Since 1849, a number of patents on magnetic separation have been issued in USA, and texts of some of the patents before 1910 describe a variety of magnetic separators for mineral processingProbably the biggest financial failure of Edison's career was the magnetic oreseparatorThe idea, which Edison's laboratory experimented with during the 1880s and 1890s, was to use magnets to separate iron ore from unusable lowergrade ores8: Magnetic Oreseparator 10 Inventions by Thomas EdisonIron ore processors may also employ magnetic separation for beneficiation of classifier output streams Wet highintensity magnetic separators (WHIMS) may be used to extract highgrade fine particles from gangue, due to the greater attraction of the former to the applied magnetic field Magnetic separation: based on the generation ofMagnetic Separation an overview | ScienceDirect Topics
