magnetic separation of fine particles

Commercial magnetic separators are continuous-process machines, and separation is carried out on a moving stream of particles passing into and through the magnetic field. Close control of the speed of passage of the particles through the field is essential, which typically rules out free fall as …

Magnetic mineralseparationtechniques are invariably selective, and not fully representative of the grain size and composition of magnetic minerals present in the sample; however,magnetic separationmay be necessary for SEM/TEM, X-ray, Mossbauer, or chemical analyses. The importance offineSD grains as remanence carriers emphasizes the necessity of making theseparationtechnique as sensitive as possible to thefine…

Magnetic separation:based on the generation of magnetic forces on theparticlesto be separated, which are higher than opposing forces such as gravity or centrifugal forces. This principle is used to separate ferromagnetic particles from crushed scrap mixtures. • Eddy current separation: is a particular form ofmagnetic separation.An alternating magnetic field induces electrical eddy currents on a metal particle
