Magnetic separation is a separation of mineral beneficiation methods, suffered the size of the magnetic force in the magnetic field are sorted according to magnetic differences between the mineral particles and minerals. According to different magnetic properties of various materials in the future by the magnetic field generated, where that can be magnetized material, are likely to be hit very attracted to, who can not be magnetized or magnetic properties of weak magnetic material can not be sucked. In order to achieve the purpose of separation.

According to the magnetic field strength of the magnetic separator, magnetic separation can be divided into strong and weak magnetic separation; when sorting based on the medium used, is divided into wet and dry magnetic separator. Magnetic Separator is widely used in other recycling workshop, the timber industry, mining, ceramics, chemical, food, etc., for particle size below 3mm magnetite, wet magnetic pyrrhotite, roasted ore, ilmenite and other materials election, also used in addition to iron work coal, non-metallic minerals, building materials and other materials. As long as the separated mineral or mineral aggregates with the appropriate particle size of the magnetic differences and for almost all the available magnetic beneficiation. The most commonly used for the separation between other minerals magnetite and iron minerals such as rare minerals, various iron minerals, manganese mineral and wolframite, garnet, biotite, hornblende. To increase the magnetic weakly magnetic minerals, and sometimes need to such mineral magnetic roasting, then magnetic separation to enhance separation efficiency.

Let us briefly explain the classification of magnetic separation equipment:

1. According to the source of generating a magnetic field different sub-types of fixed magnets and electromagnets. In general, the latter is more stronger magnetic field.
2. According iron removal process features two types of sub-dry and wet, dry gravel and materials used for the separation of iron powder, wet slurry for separating iron powder,
3. According to the structure of the machine equipment can be divided into roller, pulley. Hanging, filter and several species.
