The most important factor affecting the effect of PTMS magnetic separator on iron removal is the feed particle size. For most ores, the thickness of the feed particle indicates the separation degree of the ore monomer, that is, the separation degree of the magnetic ore particle and gangue particle. Such ores sometimes have coarse grain size, but the selection quality is not low, the main reason is that the ore distribution grain size is coarse, grind to a certain extent useful minerals and gangue are separated.
If the particle size is small, it indicates that the separation degree of mineral monomer is high, and PTMS magnetic separator can obtain satisfactory separation index. If the granularity of the ore is relatively coarse, it indicates that the mineral is not fully dissociated, the separation of the monomer is not high, on the contrary, there are more connected bodies, that is, the magnetic particles and gangue are still a considerable part of the combination.
Because the connected body is also quite magnetic, a considerable part of the selection pair can be selected up, so that the grade of the concentrate is reduced. Therefore, it is required that the PTMS magnetic separator must fully achieve monomer separation. For the ore with coarse grain size, as long as the mineral and gangue have reached monomer separation, it is not necessarily too fine.
