Magnetic material mineral particles magnetized into magnetic chains

Some of the magnetic materials contain phosphorous and other impurities, the use of conventional magnetic separation method to get the content of impurities in accordance with the requirements of the iron ore, the use of flotation method is neither economic nor environmental pollution. The use of magnetic column separation cleaning effect is obvious. For example, if a magnetite is selected by conventional magnetic separation and magnetic separation, the sulfur content can be reduced from 3.61% to 0.23%. After the conventional magnetic separation, the sulfur content dropped to 0.88%, which was a sulfur-containing unqualified product. After the magnetic column was selected, not only did the sulfur grade drop below 0.3%, but also the iron grade increased significantly, reaching 67.80%. Small-scale test and Industrial production shows that the concentration of magnetic separation towards the underflow (concentrate) can be stabilized at 55% to 65%. Therefore, in addition to the above five applications, magnetic separation can also be used as a pre-employment concentration plant.
Sorting principle The electromagnetic column selection system consists of multiple straight coils. The coils are divided into several groups from top to bottom. They are controlled by a special DC electric control cabinet, and they are turned on and off in succession from top to bottom to produce a magnetic field that moves down. Under the action of this magnetic field, the magnetic material mineral particles are magnetized into magnetic flux chains, and at the same time dispersed in the power-off coil and the upper and lower regions thereof, so that the magnetic mineral particles can undergo multiple times of magnetic polymerization and dispersion during the separation process. In the process of dispersion and polymerization, the tangentially introduced rotating updraft stream can remove the monomer gangue 34 contained therein from the magnetite concentrate to remove harmful impurities from the hopper and the feeding tube, the trough, and the sorting. Columns, electromagnetic systems, water supply pipes, kick drums, concentrate ore discharge pipes and valves, and power supply systems. 2.2 Separation principle The magnetic column selection electromagnetic system consists of multiple straight coils. The coils are divided into several groups from top to bottom, controlled by a special DC electric control cabinet, and they are turned on and off in order from top to bottom to produce magnetic fields that move down in stages. . Under the action of this magnetic field, magnetic mineral particles are magnetized into magnetic chains and dispersed at the power-off coil and the upper and lower regions thereof. Therefore, the magnetic mineral particles can undergo multiple times of magnetic polymerization and dispersion in the separation process, and are dispersed. In the process of polymerization, the tangentially introduced rotating updraft stream can carry the monomer gangue contained therein and the intermediate and lean continual body rushes to the upper end of the magnetic column to be discharged as an overflow. Single magnetic and rich connectives are discharged from the lower part of the magnetic separation under the magnetic force that is constantly moving down and gravity, and become a high-grade iron concentrate magnetic material.
