how to separate two magnets？
Magnetic separation (also known as magnetic field sorting) is a beneficiation method that separates different magnetic components in a material by different types of magnetic separators based on the magnetic differences of different components in the separated material. The surrounding space where the magnetic force of the magnet acts is called a magnetic field. The physical quantity indicating the strength of the magnetic field is called the magnetic field strength and is usually represented by the symbol H, and the unit is A/m. Mineral magnetic differences are the basis for magnetic separation. The magnetic properties of minerals can be measured. According to their magnetic strength, minerals can be divided into: ferromagnetic minerals, weak magnetic minerals, non-magnetic minerals. In the magnetic field of the magnetic separator, the ferromagnetic mineral is subjected to the largest magnetic force, the weak magnetic mineral is subjected to a small magnetic force, and the non-magnetic mineral is not subjected to a magnetic force or a weak magnetic force. In the process of magnetic separation, the ore particles are subjected to a variety of forces. In addition to magnetic force, there are gravity, centrifugal force, water flow force and friction. When the magnetic force of the magnetic ore particles is greater than the sum of the remaining forces, it will be sucked or deviated from the material flow to become a magnetic product, and the rest is a non-magnetic product to achieve separation of different magnetic minerals. Magnetic separation is a beneficiation method that uses the difference in magnetic properties of various minerals to sort in the magnetic field of a magnetic separator. When the ore particles having different magnetic properties pass through the magnetic field of the magnetic separator, they are inevitably subjected to magnetic force and mechanical force. Since the magnetic particles with strong magnetic properties and the magnetic particles with weak magnetic properties are different in magnetic force, different trajectories are generated, so that the ore particles are divided into two or more separate beneficiation products according to their magnetic properties. Magnetic separation is widely used in the selection of ferrous ore, the selection of colored and rare metal ore, the recovery of medium in heavy medium ore dressing, the removal of iron-containing impurities from non-metallic mineral raw materials, the removal of iron objects, the protection of crushers and other equipment. Recycling scrap steel from steel slag produced by smelting and removing pollutants from production and domestic sewage. In recent years, due to the development of high field strength and high gradient magnetic separators, the application fields of magnetic separation methods are still expanding, such as removal of chemicals, paramagnetic particulate impurities in drugs, and the like.
