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
Get PriceIron 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
Invented the magnetic ore separator. In the year 1880, he: Discovered the “Edison Effect,” the fundamental principle of electronics. In the year 1885, he: Discovered a system of wireless induction telegraph between moving trains and stations. He also patented similar systems for ship-to-shore use. In the year 1891, he:
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
Magnetic separation is a well-developed area and many devices have been invented. In the future, industrial stage will only be achieved by the magnetic separators which present some economical advantages. Thus, we should design magnetic separators which are capable to perform many tasks at the same time, and/or to improve the relation accuracy

CTN Series Countercurrent. CTN series countercurrent wet drum magnetic separator is designed for handling minerals with particle sizes from 0-0.5mm, especially for mineral with particle size from 0-0.15mm, it is suitable for primary separation and scanning operation of fine-grained magnetic ore.The slurry will pass through a long separation zone, to achieve the
The magnetic separator consists of a large electromagnet through which mineral mixtures can be passed on a metal trough which is divided near its exit end. Varying the strength of the magnetic field and/or slope of the separation trough is used to separate minerals. All forms of mineral separation suffer from one difficulty
Oct 02, 2009 1880 Invented a magnetic ore separator. Invented and installed the first life-sized electric railway for handling freight and passengers at Menlo Park, N. J
At these mines, a device called a Wetherill's Magnetic Separator (invented by John Price Wetherill, 1844–1906) was used. In this machine, the raw ore, after calcination was fed onto a conveyor belt which. passed underneath two pairs of electromagnets under which further belts ran at right angles to the feed. belt
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
