Dry magnetic separator, as a key part of a pre-discarding tailings process, can not only improve the iron grade of raw ore, reduce the costs of grinding, screening, separation and tailings dewatering, but also obtain coarse-grain dry tailings that can be sold directly, which dramatically reduces the cost of mineral processing (Ezhov and ...
After passing through several rollers and mesh screens, the finely crushed material falls in a thin sheet in front of a series of magnets, which deflect the magnetic particles …
The magnetic separator structure comprises a belt, drum, or plate with an embedded magnet. As mineral mixtures pass through the separator, the magnet draws the magnetic particles while allowing the non-magnetics to flow through unaffected. Permanent vs. Electromagnetic Separators. There are two primary types of magnetic separators: Permanent ...

Footnote 56 Other than briefly trying to apply his magnetic ore separator commercially to iron bearing sands in 1881–82, Edison did not return to it until the end of the decade. Figure 9.6 shows Edison's iron ore processing and mining patents. Edison applied for a number of patents related to his magnetic extraction technology but the ...

Invented and installed the first life-sized electric railway for handling freight and passengers at Menlo Park, N. J. 1881 Opened business offices at No. 65 Fifth Avenue, New York City. Established his second and improved commercial ...
Thomas Edison responded by developing an efficient means of extracting pure iron from low-grade magnetite. After spending over a decade in attaining technical and commercial success, he admitted defeat as even …
He designed rock-crushing technology and an electromagnetic ore separator to extract the low-grade magnetite iron ore from the crushed boulders.

In an attempt to provide cheap iron ore in the late 19th century, Thomas Edison spent millions of dollars commercializing electromagnetic ore-separation techniques in the eastern U.S.
Edison's patents are in the public domain and have been made available through the generosity of David Kovanen. Publisher The Thomas A. Edison Papers
As the Inventor of Vertical Pulsating High Gradient Magnetic Separator(VPHGMS), he has never stopped the research on magnetic separation over the past 30 years. His research isn't more than just theory, and focuses on practical application, which has realized the breakthrough of vertical pulsating high gradient magnetic separation technology ...
Development of large magnetic separator units can increase the ore treating capacity, reduce energy consumption, and save space. The largest permanent magnetic drum separator available is believed to have a drum diameter of 1800 mm and a length of 5000 mm, with a processing capacity of 250–300 tons of magnetite ore per hour. ...
Edison had developed an electromagnetic ore separator in 1880 while working on electric light and power. In this device, sand from tailings or crushed rock was poured through a hopper so that it fell in a thin, broad stream in front of an electromagnet that attracted magnetic particles, such as iron, into one receptacle while non-magnetic ...

In this investigation, a full-scale cDMS1000 separator was used to evaluate the cDMS performance for fine magnetite ore. As shown in Fig. 1, the cDMS1000 separator is mainly composed of feeder, driving mechanism, separation cone, dust hood, receiving funnels and support frame.In the separator, a permanent magnet system was adopted, and it operates in a …
His interest spread to gold and iron processing, and he devised a magnetic ore-separation technique that was patented in 1880. By then he had organized the Edison Ore-Milling …
Wet drum magnetic separator can be used for recovery of fine and strong magnetic minerals or removal of small amounts of ferromagnetic materials from non-magnetic minerals. Wet drum magnetic separator is suitable for beneficiation of magnetite, pyrrhotite, hematite, limonite, siderite, etc. Different tank styles are available to meet varying ...

This photograph shows inventor Thomas Alva Edison at work in his West Orange, New Jersey, laboratory. Edison directed teams of research assistants here for nearly fifty years -- from 1887 until his death in 1931. More than half of …
Edison planned to process 1200 tons of iron ore every twenty hours. The plant had three magnetic separators that could produce a total of 530 tons of refined ore. There was other equipment to re-refine what was left over …
The residual fraction from the first magnetic stage passes via a discharge directly onto a downstream, fast-running magnetic separator equipped with strong neodymium permanent magnets. The high supply speed significantly loosens the material flow and all weakly magnetic impurities – like ferrous dust, clumps or fluff – can easily be removed ...
During the 1890s, Thomas Edison launched a New Jersey mining operation to address an iron ore shortage. He designed rock-crushing technology and an electromagnetic ore separator to extract low-grade ore from crushed boulders. The final product -- a briquette made of powdered iron ore -- didn't do well commercially, especially after high-grade ore was discovered around …
In 1891, Thomas Edison built a huge iron mining complex around some pre-existing mines on Sparta Mountain in Sussex County. This operation took a lower-grade iron ore, crushed it, magnetically ...

separation is used to enrich iron ore samples that demonstrate either para- or ferromagnetic behavior (Flippov et al. 2014). Magnetic separation can be performed on wet or dry material, with wet being a slurry (Flippov et al. 2014). Magnetic separators are broken down into two categories: high and low intensity (Flippov et al. 2014). Low
