The magnetic separation method of PTMS magnetic separator is used to remove weakly magnetic impurity minerals such as hematite, limonite and biotite including intergrowth particles. High intensity magnetic separation usually uses wet PTMS magnetic separator or high gradient magnetic separator.
Generally speaking, the impurities to limonite, hematite, biotite and other weak magnetic impurity mineral quartz, the use of wet PTMS magnetic separator in 10000 Oe above can be selected; It is better to use weak magnetic machine or medium magnetic machine to separate the strong magnetic minerals mainly containing magnetite.
The experimental results show that the magnetic separation times and magnetic field intensity of PTMS magnetic separator have an important influence on the effect of iron removal. With the increase of magnetic separation times, the iron content gradually decreases, and most of the iron can be removed under a certain magnetic field intensity. However, the iron removal rate does not change much after the magnetic field intensity increases a lot. In addition, the finer the grain size of quartz sand is, the better the effect of iron removal is, because of the high amount of iron-containing impurity minerals in fine quartz sand.
