  • 8 Magnetic Ore separator 10 Inventions by Thomas Edison

    Probably the biggest financial failure of Edison's career was the magnetic ore separator. The idea, which Edison's laboratory experimented with during the 1880s and 1890s, was to use magnets to separate iron ore from unusable lower grade ores. This would mean that abandoned mines could be profitable

  • Concentration of Ores Hydraulic Washing, Froth Flotation

    In this method of Magnetic Separation, we use the magnetic properties of certain metals to divide them from the non magnetic gangue. Here we place the powdered ore on a roller belt. One belt of this roller is a magnet. So the magnetic material attracts to the metal belt and stays on the belt. The non magnetic gangue falls in a heap from the belt.
