Who invented magnetic separator and when

Apr 06, 2021

Thomas Edison’s Magnetic Iron Ore Separator . Thomas Edison experimented during the 1880′s and 1890′s with using magnets to separate iron ore from low grade, unusable ores. His giant mine project in northwestern NJ consumed huge amounts of money as experimentation plodded forward

    Magnetic Separation - Mining Fundamentals

    Iron ores are usually subjected to the magnetic separation process, due to the high magnetic susceptibility of iron. Magnetic separation was first applied to the separation of wolframite from cassiterite. The first magnetic separator, invented by John Prince, consisted of two pairs of electromagnets with a feed belt running over them

    Magnetic Separation - an overview | ScienceDirect Topics

    Magnetic separation takes advantage of the fact that magnetite is strongly magnetic (ferromagnetic), hematite is weakly magnetic (paramagnetic), and most gangue minerals are not magnetic (diamagnetic). A simple magnetic separation circuit can be seen in Figure 1.2.5 [9].A slurry passes by a magnetized drum; the magnetic material sticks to the drum, while the
