what is magnetic separation in Feldspar？
1. The most important factor affecting the magnetic separation effect of the magnetic separator is the feeding size of the magnetic separator. The thickness of the ore-bearing grain size indicates the degree of separation of the ore monomer, that is, the degree to which the magnetic ore particles are separated from the gangue particles. If the ore particle size is small, it indicates that the mineral monomer has high separation degree and can obtain satisfactory selection index; if the ore particle size is relatively coarse, it indicates that the mineral is not fully dissociated, the monomer separation degree is not high, and the opposite body is more That is, the magnetic particles and the gangue still have a considerable portion combined. Since the continuous body is also quite magnetic, the selection can be selected for a considerable portion to reduce the concentrate grade. Therefore, it is required that the minerals to be fed into the magnetic separator must sufficiently achieve monomer separation. For the ore with a coarse grain size, as long as the mineral and the gangue have reached the monomer separation, the particle size is not necessarily too fine. Such ore sometimes has a coarser grain size, but the quality of the sorting is not low. The main reason is that the size of the ore is coarse, and the useful mineral and the gangue are separated to some extent.
2. The slurry concentration is one of the main factors affecting the magnetic separation effect of the magnetic separator. It mainly refers to the overflow concentration of the classifier. If the concentration of the slurry is too large, resulting in too high a sorting concentration, the quality of the concentrate will be seriously affected. Because the concentrate particles are easily covered by finer gangue particles and the package is not separated at this time, they are selected together to lower the grade. If the concentration of the slurry is too small, the concentration will be too low, and the flow rate will increase. The selection will shorten the pairing, so that some small magnetic particles that would have been available should fall into the tailings to increase the grade of the tailings and cause losses. Therefore, the pulp concentration should be adjusted as needed. The adjustment at the magnetic separator is mainly adjusted by the size of the blown water for the mine. However, the most important thing is that the graded overflow concentration must be completed according to the magnetic separation requirements. The maximum concentration of the feed slurry should not exceed 35%, and the control is generally about 30%. It should be determined according to the actual situation.
3. Points to note when using a magnetic separator: The magnetic separator should be installed at the beginning of the conveyor transport system. The design of the magnetic separator is usually not necessary in any existing retrofit conveyor system without relocating the main equipment. The magnetic separator can also be used in combination with metal detectors to provide complete peace of mind. This will ensure that the embedded or any metal material or trapped under the mine may escape the magnetic separator without passing through the metal detector. Once the metal detector is triggered, the conveyor belt will stop and human intervention is necessary. If the ore particle size is relatively coarse, it means that the mineral is not fully dissociated, and the monomer separation is not high. On the contrary, there are more organisms, that is, the magnetic particles and the gangue still have a considerable part combined. Therefore, it is required that the minerals to be fed into the magnetic separator must sufficiently achieve monomer separation.
