The finer the particle size of quartz sand, the better the iron removal effect, which is due to the high amount of iron impurity minerals in fine grained quartz sand. An experimental test is carried out in the PTMS Electromagnetic Separator purification process of high purity quartz sand. The results show that the impurity removal rate increases with the increase of magnetic field intensity. When the magnetic field intensity reaches 100000e, the impurity removal rate does not increase significantly.

PTMS magnetic separation

 
Therefore, the appropriate magnetic field strength should be 100000e. After PTMS Electromagnetic Separator, the grade of Si02 in 40 mesh is 99.05% and the content of Fe203 is 0.071%; the grade of Si02 in 40-80 mesh is 99.09% and the content of Fe203 is 0.070%. 80-140 mesh Si02 grade 99.14%, Fe203 content 0.067% : 140-200 mesh Si02 grade 99.10%, Fe203 content 0.069%. However, quartz sand contains more impurities, especially when it contains more weak magnetic or non-magnetic impurities, only magnetic separation can not be purified into high purity quartz sand.

In the various application fields of quartz sand, iron is the most harmful impurity, and the PTMS Electromagnetic Separator of quartz sand is generally purified to remove iron. Quartz sand after iron removal can obtain refined quartz sand or high purity quartz sand (such as electronic grade products).
