Magnetic Separation
Magnetic separation takes advantage of differences in the magnetic properties of minerals. Minerals fall into one of three magnetic properties: ferromagnetic, paramagnetic and diamagnetic. Ferromagnetic minerals are themselves magnetic (i.e., magnetite and pyrrhotite) and can be easily separated from other minerals with a magnet since they will ...

What is magnetic separation? - ChemistryRack
The magnetic separation is a physical separation technique which is based mixtures or using the magnetic properties of the material, such as its sensitivity to the attraction or repulsion magnets. It is also known as magnetization, because the objects that can be separated by this technique are magnetized by the magnetic field of the magnets.

seperation of dolomite from manganese
Strong magnetic separation. Manganese minerals are weak magnetic minerals (specific magnetization coefficient X=10×10-6~600×10-6cm3/g), can be effectively recovered in a strong magnetic field magnetic separator with a magnetic field strength of Ho=800-1600kA/m (10000-20000oe), and the grade of manganese can generally be increased by 4-10%.

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.
