In recent years, a low-grade vanadiferous titanomagnetite concentrate (LVTC) produced in the northwest area of Liaoning has attracted more and more attention. However, it is difficult to recover and utilize valuable minerals such as iron, titanium, and vanadium, due to their special physical and chemical properties and complex mineral …
In this regard, the physics of magnetic separation at the microscale is not unlike that of gravitational sedimentation, or sedimentation in a centrifugal field, in that the range of separation is bounded at the small particle size limit by the randomizing effect of thermal motion, and also strongly depends on the separation-specific property of the …
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, and environmental remediation. The fundamental principle underlying …

Magnetic separators use basic magnetic principles to remove ferrous material from substances such as granules, grains, pellets, powders and paste.
1.1. Principles of Magnetic Particle–Based Separations Magnetic particles are available in a variety of types and sizes, but the prin-ciple of the technique is the same for all types, and is outlined in Fig. 1. The magnetic particle is coated with a hapten that recognizes a receptor on the target cell wall or molecule.

A magnetic separator applies basic magnetic principles to remove ferrous based and paramagnetic metals from a range of substances including powders, granules, liquids, pellets or pastes. They are usually installed within the product stream at key HACCP or inspection points. See Our Guide To Selecting The Right Magnetic Separator.
The fine chromite was observed to be upgraded to a Cr:Fe ratio of 2.2 with a yield of 55.7% through the use of an induced roll magnetic separator and a feed material with a Cr:Fe ratio of 1.6 ...
In recent decades, it has become one of the key separation technologies in the utilization of the ores that contain magnetic minerals, such as iron oxides, ilmenite, wolframite, and manganese, and in the …
Magnetic separation is a versatile technique used in sample preparation for diagnostic purpose. For such application, an external magnetic field is applied to drive the separation of target entity (e.g. bacteria, viruses, parasites and cancer cells) from a complex raw sample in order to ease the subsequent task(s) for disease diagnosis.
With ever faster processes and cutting speeds it's a vital consideration. Since inventing the world's first permanent magnetic chuck in 1934 we have remained at the forefront of workholding systems. We offer a range of permanent magnetic chucks and electro-permanent magnetic chucks for clamping or holding in grinding, milling and cutting ...
Hematite ore's magnetic characteristics were significantly impacted by magnetizing roasting. By selectively magnetizing roasting, hematite is transformed into magnetite.
