The conventional magnetic separators used in the mineral industry are equipped with traditional magnetic circuits or with permanent magnets (rare earth). However, when processing minerals with low magnetic susceptibilities or minerals of very small particle size, these separators are inefficient. In addition, a conventional magnetic …
Pulsating high-gradient magnetic separation (PHGMS) of fine hematite from tailings was studied using a pilot PHGMS separator to investigate the possibility of its application in industry. The results of this investigation indicate that PHGMS is effective for recovering fine hematite from the tailings and greatly improved the separation …
Coal-based reduction followed by magnetic separation is a promising technology for processing refractory iron ores. Analysis of the size distribution of metallic iron particles is an effective approach for exploring the mechanisms of coal-based reduction. As metallic iron particles exhibit very complex shapes compared with nature ores, …
Magnetic separation is a physical separation technique that exploits the difference in magnetic properties between materials to achieve separation. It has been applied in diverse fields, including mining, mineral processing, waste management, biomedical research, …
Magnetic susceptibilities of minerals. Magnetic separation of minerals is a topic that is seldom reported in the literature for two reasons. First, separation data generally are byproducts of other projects; and second, this study requires a large amount of patience and is unusually tedious. Indeed, we suspect that most minerals probably are ...
First Online: 31 March 2023. 9 Accesses. Download reference work entry PDF. Magnetization and magnetic separation is a method of magnetic separation by enhancing the volume magnetism or surface magnetism of minerals. By changing the volume magnetism (volume magnetization) or surface magnetism (surface …
Magnetic separation is widely used. All materials with magnetism in the magnetic field can be treated by magnetic separation, which is the main method to treat iron ore. All lean magnetite ores need to remove gangue minerals such as quartz through weakly magnetic field magnetic separators to improve the iron grade of concentrate. …

Five kaolin crudes from the state of Georgia in the U.S. were investigated for processability with chemically enhanced magnetic separation (CEMS) technologies developed by Cytec. The technologies used magnetic reagent alone or in conjunction with specialty chemicals to selectively agglomerate and magnetize the desired minerals (impurities) to be removed …
One possibility that has been explored is magnetohydrostatic separation or magnetic separation of the second kind. This type of separation is not the same as high gradient magnetic separation. In the latter case, material is separated based on the magnetic behavior of the individual particles placed in a magnetic field.
Development of magnetic separators based on powerful permanent magnetic materials, construction of reliable superconducting separators, design of efficient eddy-current …
Gravity separation has also been used to process very fine rare earth minerals using centrifugal gravity concentrators such as the Mozley multi-gravity separator [53,54]; the falcon separator [55 ...
The magnetic product obtained after magnetic separation was mainly ferronickel alloy. The three parameters were optimized in sequence. Initially, the effects of roasting temperature with a range from 1000 to 1300 °C at an interval of 50 °C, magnetic field strength from 50 mT to 250 mT at an interval of 50 mT and a grinding time of 2 h …
This book treats magnetic separation from the point of view of both the engineer in the field who operates magnetic separators and the research scientist in the laboratory. It emphasizes those aspects of magnetic separation where lack of support in fundamental research is most evident. The intention is to bring the engineer and the scientist closer …
Kaolin samples from Rio Capim Resources were treated in conventional and superconducting magnetic separators to study the main variables that influence the impurity removal process. Two coating clays and a delaminated clay were tested. The variables studied were retention time (cross-sectional velocity), magnetic-field intensity …
A magnetic separation test from an unleached ore sample was also carried out as a benchmark. To the best of our knowledge, this is the first time that a magnetic separation process was used to a residue obtained from reductive acid leaching of manganiferous iron ores to recover iron. ...

Magnetic separation following DMS is an effective and inexpensive method to reduce the DMS concentrate prior to final recovery processes. It reduces the number of X-ray …
In the Esfordi area, this method was used by us for the first time to identify, separate and interpret geophysical (magnetic) anomalies. The main aim of this thematic and practical study is the qualitative interpretation of geophysical data, the application of new methods in the prospecting and exploration of mineral deposits, modeling the ...
The use of magnetic separators offers multiple benefits. First, they contribute to the quality enhancement of products by eliminating magnetic particles. This results in increased consumer trust and regulatory compliance. Second, they protect processing machinery from potential damage caused by metal contaminants, reducing …
Conventional magnetic separation devices are widely used for the removal of tramp iron from a variety of feed materials and for the beneficiation of ferrous ores. These devices for separation of strongly magnetic materials employ a variety of mechanical designs. Recently developed high gradient magnetic separation devices extend the useful …
Used to concentrate moderately magnetic ores. It consists of two or more horseshoe electromagnets, arranged one above the other. The cross – belts prevent the magnetic particles from adhering to the pole. The poles of the upper magnets are wedge shaped while the lower poles are flat. It permits a much smaller air gap than the belt …
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 …

Magnetic methods are more popular in mineral exploration than gravity, not least because magnetic data can be quickly recorded from the air and in conjunction with other geophysical surveys. Land gravity surveys, by contrast, may require greater field efforts (Figs. 1, 5 and 6), more time, and more commitment of scarce capital.
Laboratory investigations on the possibility of using magnetic separation for the recovery of sulfide minerals have been reported. A survey of several sulfide ores and flotation concentrates indicated that, in most cases, magnetic separation is not a suitable primary beneficiation method.
