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 nonmagnetic 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 lessGet Price
Probably the biggest financial failure of Edison39s career was the magnetic idea, which Edison39s laboratory experimented with during the 1880s and 1890s, was to use magnets to separate iron ore from unusable lowergrade ores.
The removal of particles from solution with the use of magnetic fields is more selective and efficient and often much faster than centrifugation or filtration 13 and, as a result, magnetic separations are used in areas as diverse as biotechnology and ore refinement 47.Central to the process is the generation of magnetic forces on particles large enough to overcome opposing forces
Wet Magnetic Separation of Cornwall Ore. During the dry magnetic separating tests on Cornwall ore, it became evident that this process of magnetic separation was not suitable for this ore, for the following reasons Dust. The ore must be very dry in order to secure freedom of motion between the particles, or poor separation will result.
The method of magnetic separation is the process of separating ore from the gangue particles based on the magnetic properties of either ore or matrix. In this method, the ore is finely crushed and then passed over the magnetic roller, where one is magnetic, and the other is nonmagnetic.
Testwork has been performed on iron ore samples from various locations to validate the use of magnetic separation following classification Horn and Wellsted, 2011. A key example was material sourced from the Orissa state in northeastern India, with a summary of results shown in Table 10.2 .
Magnetic Separation is one of the physical concentration processes that utilizes the differences in magnetic properties of various minerals present in the ore body. The magnetic fraction may be valuable or gangue depending upon its end use in a particular process and so also the nonmagnetic fraction, e.g., separation of magnetite magnetic
MAGNETIC SEPARATIONThis is based on differences in magnetic properties of the ore components. If the ore particles are magnetic and the nonmagnetic material is gaungethis method is used.
Magnetic separation is most commonly used in the mining industry to separate tramp ore, or unwanted waste metals, from the rest of the bulk material. Tramp ore typically consists of the manmade byproducts created by the mining process itself, such as wires from explosive charges, nuts and bolts, nails, broken pieces from hand tools such
A number of magnetic separation processes are used to study preparability of two main hematitemagnetite and magnetitemuscovite ore types extacted it the Abagas iron ore deposit. The dry magnetic
magnetic separation. Case studies Several case studies are presented that describe the testing and flowsheet development work that enabled proper magnetic separation technology selection and flowsheet configuration. Case Study 1 Dry magnetic separation of ilmenite before electrostatic separation The deposit for Case Study 1 was a typical aeolian
Wet High Intensity Magnetic Separator WHIMS The WHIMS range includes 4, 16, 24 and 48 pole machines with either 68 or 120 millimetre separation matrix widths. WHIMS separators are suitable for applications requiring higher magnetic field gradients to remove weakly magnetic particles from nonmagnetic concentrates.

Magnetic separation has two major applications in mineral processing plants The removal of tramp iron which would deleteriously affect subsequent processes from an ore stream. This is usually achieved by a low intensity magnet suspended above, or at the head of, a conveyor. Separation of magnetic minerals from less magnetic minerals.
Magnetic separation takes advantage of natural magnetic properties between minerals in feed. The separation is between economic ore constituents, noneconomic contaminants, and gangue. Magnetite and ilmenite can be separated from their nonmagnetic rockforming minerals of host rock as valuable products or as contaminants. The technique is widely
This method of separation is used when either the ore particles or the gangue associated with it possess magnetic properties. For example, chromite FeCrO 2 2 being magnetic can be separated from the nonmagnetic silicious gangue by magnetic separation.. This method is widely used for the separation of two minerals, when one of them happens to be magnetic.
Magnetic separation exploits the different magnetic properties in ore bodies to retrieve target minerals from gangue. The process utilises the competition between gravitation, centrifugal and friction forces, magnetic forces, and interparticle attraction or repulsion.
Magnetic separation is a process in which magnetically susceptible material is extracted from a mixture using a magnetic force. This separation technique can be useful in mining iron as it is

Gravity separation is one of the oldest technique in mineral processing but has seen a decline in its use since the introduction of methods like flotation, classification, magnetic separation and leaching. Gravity separation dates back to at least 3000 BC when Egyptians used the technique for separation of gold.
Magnetic Separation and Iron Ore Beneficiation. 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 separation have been issued in USA, and texts of some of the patents before 1910 describe a variety of magnetic separators for mineral processing.
