Paul A. Beharrell BSc MSc PhD Quantum Design

Magnetic separation is a technique which allows materials with different magnetic properties to be separated by the use of inhomogeneous magnetic fields. The separation is achieved using a combination of a magnetic field and a field gradient which generates a force on magnetisable particles as shown in the following equation. B B V F P m

Working principle and application of magnetic separation

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.

US7771509B1 Magnetic oxygen concentrator for air streams

A process for separating O 2 from air, that includes the steps effecting an increase in pressure of an air stream, magnetically concentrating O 2 in one portion of the pressurized air stream, the one portion then being an oxygen rich stream, and there being another portion of the air stream being an oxygen lean stream, compressing the oxygen rich stream and removing water and carbon dioxide

A novel magnetic separation oxygen-enriched method and the

The enrichment level is significantly influenced by the gas temperature and the magnetic field. The maximum increment of oxygen concentration drops to 0.16% when the gas temperature rises to 343 K, and drops to 0.09% when the maximum product of magnetic flux density and gradient is reduced to 101 T 2 /m from 563 T 2 /m.

US5705628A DNA purification and isolation using magnetic

A method of separating polynucleotides, such as DNA, RNA and PNA, from a solution containing polynucleotides by reversibly and non-specifically binding the polynucleotides to a solid surface, such as a magnetic microparticle, having a functional group-coated surface is disclosed. The salt and polyalkylene glycol concentration of the solution is adjusted to levels which result in polynucleotide

Magnetic Separation an overview ScienceDirect Topics

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 the drum, while the nonmagnetic slurry keeps flowing.

Low-Field Magnetic Separation of Monodisperse Fe3O4

Nov 10, 2006 Magnetic separations at very low magnetic field gradients (<100 tesla per meter) can now be applied to diverse problems, such as point-of-use water purification and the simultaneous separation of complex mixtures. High–surface area and monodisperse magnetite (Fe3O4) nanocrystals (NCs) were shown to respond to low fields in a size-dependent fashion.

Concentration and recycling of rare earth elements (REEs

The electron microprobe showed that high amounts of REEs were distributed on the fluorapatite mineral, and hence, it was necessary to remove the high magnetic minerals by a low-intensity magnetic separation using a magnetic drum in an experimental procedure. A cyclic magnetic separator was used for the low-gradient magnetic separation.
