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 once again through the extraction of iron from sand at the sites. At the time, iron ore prices

Magnetic separation is an old technique for the concentration of iron ores and for the removal of tramp iron. Since 1849, a number of patents on magnetic
Effectively process fine, weakly-magnetic minerals with the Outotec SLon® Vertically Pulsating High-gradient Magnetic Separator (VPHGMS). The unit is a wet, high-intensity magnetic separator that uses a combination of magnetic force, pulsating fluid, and gravity to process minerals. The advanced features are incorporated into a design utilizing a unique vertical configuration, jigging action
useful to concentrate this type of ore. These two techniques were adopted for the beneficiation of the Wadi Halfa low-grade iron ore. As a result of the fine dissemination of the iron minerals and the most abundant gangue mineral, quartz, the optimum degree of grinding is around 150 micrometers. The rougher tests of both the gravity separation and magnetic separation produced concentrates of
Wet drum magnetic separators of special design may be used as a magnetic thickener for thickening purpose of magnetic concentrates, usually at the end of a magnetic separation process, or as a high-intensity magnetic separator, for the removal of very fine ferromagnetic particles and iron corrosions produced in the grinding process of a nonmetallic ore processing flowsheet, at a magnetic
9 Developments in the physical separation of iron ore: It is a potential dry magnetic separator for oxidized iron ore beneficiation. 9.6. Summary . The majority of iron ores occurring naturally on earth are low-grade and need to be upgraded prior to use in metallurgical processes. Magnetic separation is the most important method for upgrading low-grade iron ores to high-quality iron ore

The results of this study demonstrated that low-grade iron ore fines can be upgraded by means of STET tribo-electrostatic belt separator. Based on STET experience, the product recovery and/or grade will significantly improve at pilot scale processing, as compared to the bench-scale test device utilized during these iron ore trials.
Star Trace Industrial Magnetic Iron Separator are primarily designed and manufactured as low field intensity separators.They have an open magnetic system with the magnetic poles located in one plain. Low field intensity separators are employed for separating iron particles from bulk material whenever foreign iron disturbs the subsequent process sequences.
Magnetic separation is the process of separating components of mixtures by using magnets to attract magnetic materials. The process that is used for magnetic separation detaches non-magnetic material with those who are magnetic. This technique is useful for not all, but few minerals such as ferromagnetic (materials strongly affected by magnetic fields) and paramagnetic (materials that are less
The recovery of fine iron ore by magnetic separation will decrease with decreasing particle size because the magnetic susceptibility of magnetic particles decreases with a decrease in particle mass. There is an example of an Australian iron- ore operation that introduced beneficiation of fine haematite, –100 µm, by using WHIMS2. The WHIMS feed was deslimed at 10 µm, with the –10 µm
Lower-grade sources of iron ore generally require beneficiation, using techniques like crushing, milling, gravity or heavy media separation, screening, and silica froth flotation to improve the concentration of the ore and remove impurities. The results, high-quality fine ore powders, are known as fines. Magnetite. Magnetite is magnetic, and hence easily separated from the gangue minerals and
