Who invented magnetic separator and when

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 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 nonmagnetic slurry keeps flowing

    A Davis Tube is a laboratory instrument designed to separate small samples of strongly magnetic ores into strongly magnetic and weakly magnetic fractions. It has become a standard laboratory equipment used for the assessment of the separability of magnetic ores by low-intensity magnetic separators. It was developed in 1921 and no significant changes have been made in its design since then. The

    Magnetism: History of the Magnet. The history of magnetism dates back to the 600 BCE, where we find mention of Lodestone in the work of Greek philosopher Thales of Miletus. Early lodestone, found in the Greek region of Magnesia, Anatolia is where the modern name “magnet” is derived. The earliest Chinese reference to “Lodestone” occurs in the 400 BCE in “The Book of the Devil Valley Master.”
