Magnetic particle imaging (MPI) is a promising medical imaging technique for visualizing the three-dimensional distribution of tracer materials, specifically iron oxide nanoparticles (IONP). The optimization of magnetic nanoparticles (MNP) plays an essential role to improve the image resolution and sensitivity of imaging techniques.
Gravity separation and magnetic separation are mainly used to separate coarse-grained and medium-grained weakly magnetic iron ore (20~2 mm). During gravity separation, heavy medium or jigging methods are commonly used for the gravity separation of coarse and very coarse (>20 mm) ores; spiral chutes, shakers and centrifugal concentrators …

In addition, the rate at which the iron-containing masses are separated from the nonferrous metal melt can be controlled by controlling the strength and gradient of the applied magnetic field. Following physical separation from the iron-rich portion of the melt, the iron-depleted portion can then be cast into shaped articles of manufacture or ...
Magnetic separation is the process of separating mixtures of two solids, one of which has magnetic properties. It is based on the distinction between magnetic and non-magnetic materials. Iron particles in the mixture of iron and Sulphur are attracted to the magnet and separate from the non-magnetic substance. Solved Questions

Magnetic separation may be used for coal beneficiation when the gangue minerals contain such iron phases, however their very weak magnetic susceptibilities would require strong magnetic field strength (Dwari and Rao, 2009). Previous works on the magnetic separation of pyrite from coal have shown pyrite to be a weakly paramagnetic mineral.
