magnetic separators are followed by fine sifting. If there is no influence of magnetic agglomeration, the product under the fine screen should have fine particle size and higher grade than the product on the screen, because the gangue and connected body particles such as quartz are often coarser than the magnetite particles and the density is smaller. At this time, PTMS magnetic separator plays both the role of classification and separation.
However, if the magnetite particles are agglomerated because of remanence, they can not pass through the sieve but enter the PTMS magnetic separator on the sieve product, so that the screening efficiency of the fine sieve is reduced, and the sorting effect is worse. It is necessary to demagnetize the fine sieve feed ore. When conditions do not permit, it is best to add at least one demagnetization operation before or between several selections. Of course, when the magnetic agglomeration is not obvious or the grade of the concentrate is not high, it is not necessary to demagnetize.
Continuous magnetic separation operation, that is, one or more PTMS magnetic separator operations followed. The purpose of selection is to improve the grade of concentrate, and the magnetic group often contains gangue, biota or slime, the magnetic group does not open, these impurities are not selected out, is bound to affect the quality of concentrate. Therefore, before each selection, the demagnetizer should be added for demagnetizing.
