Separation Hazards and Wastes; The technique of electromagnetic separation is based on the same principles as mass spectrometry. When charged particles, such as uranium nuclei, are accelerated through a magnetic field, their trajectories are shaped by this field. Lighter particles are deflected farther from the straight-line path than heavier ...

3.11.2.5 Magnetic Separation. Magnetic separation is a process where a contaminant is first attached onto a magnetic carrier material (e.g., magnetite), and subsequently, the contaminant-laden carrier is separated under a magnetic field. The simplest magnetic separator is a permanent magnet.
Magnetotactic bacteria (MTB) offer a unique approach to metal accumulation and separation from water systems. This paper proposes an integrated separator design, for the production of MTB, the metal uptake phase and their subsequent separation. Applied magnetic fields are used to orientate the bacteria, so that they swim in a …
Magnetic fluid separation is a separation method that takes magnetic fluid as the separating medium and makes different minerals suspended in layers in the magnetoelectric field and gravity field in accordance with their magnetic intensity (or electric property contrast) and density under the action of an external magnetic field, …

The direction of the magnetic force on a moving charge is perpendicular to the plane formed by b →v and →B and follows the right-hand rule-1 (RHR-1) as shown. The magnitude of the force is proportional to q, v, B, and the sine of the angle between →v and →B.

This is abitrary, because all materials, solids, liquids and gases, have definable magnetic properties. The success of a separation depends on the difference in magnetic response and the rate at which the separation may be carried out depends on the magnitude of the response of the "more magnetic" material.

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 …

For 500 °C, this value of the magnetic field to cause phase separation is 1500 G. At 600 °C, 1000 G magnetic field is enough to initiate phase separation.
