Types of Magnetic Separators. The type of magnetic separator used by a mine depends on what material they are extracting and how much tramp ore is generated by their process. As a result, separators of different magnetic flux, or power, can be used. There are 2 types of magnetic separators; electromagnetic and permanent.

Magnetic separation theory The magnetic separation process is complex in many respects due to varying magnetic susceptibility of the material and its particle size. The magnetic force on a specific particle depends upon these factors as well as other properties, such as magnetic flux and mag-netic field gradient, created by the magnetic separator.
The differences in magnetic susceptibility can be utilized to separate a valuable mineral from its gangue through the magnetic separation method. Similar to other materials, minerals are generally classified into three …
Conventional magnetic separation devices are widely used for the removal of tramp iron from a variety of feed materials and for the beneficiation of ferrous ores.
