The use of PTMS magnetic separator separation process can maximize the removal of weakly magnetic impurities including hematite, limonite and biotite, including intergrowth particles. High intensity magnetic separation usually uses wet high intensity 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 can be selected above 10000 ost; Strong magnetic mineral of impurity is given priority to with magnetite, weak magnetic machine is adopted for magnetic machine in or effect is good, high intensity magnetic machine of quartz sand were studied experimental conditions, the results show that magnetic separation and magnetic field intensity had important effect on iron removal effect, with the increase of the number of magnetic separation, the iron content gradually decreased, and the intensity of a magnetic field can remove most of the iron, However, the iron removal rate did not change much after the magnetic field intensity increased 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. When the original quartz sand contains more impurity minerals, scrubbing, desliming and PTMS magnetic separation cannot purify quartz sand into high purity sand. In order to further improve the purity of quartz and reduce impurities.
