what is magnetic separation in Feldspar？
Washing and grading de-sludge is the primary treatment of quartz sand, which removes the thin film iron and blocking impurity minerals on the quartz sand surface, but the effect is not significant. Scrubbing is to remove the thin film iron, the bonding and muddy impurity minerals on the surface of the quartz sand by mechanical force and the grinding and peeling force between the sand grains, and to further smash the unassembled mineral aggregates, and then further purify the quartz sand by the classification operation. effect. The magnetic separation method can remove the impurities contained in the quartz sand particles to the utmost extent, and the weak magnetic impurity minerals such as hematite, limonite and biotite, and the magnetite-based ferromagnetic minerals. For weak magnetic impurity minerals, a strong magnetic machine of 100,000 e or more is often used. For minerals with strong magnetic impurities, a weak magnetic machine or a medium magnetic machine is often used for magnetic separation.
In general, the number of magnetic separations and the strength of the magnetic field have an important influence on the effect of magnetic separation and iron removal. With the increase of the number of magnetic separations, the iron content is gradually reduced; while under a certain magnetic field strength, most of the iron can be removed, 40 mesh. The grade of Si02 can reach 99.05%, the content of Fe203 is 0.071%: the grade of Si02 of 40-80 mesh is 99.09%, the content of Fe203 is 0.070%; the grade of 80-140 mesh Si02 is 99.14%, the content of Fe203 is 0.067%: the quality of 140-200 mesh Si02 is 99.10%. The Fe203 content is 0.069%. The finer the iron removal effect of quartz sand, the better the inclusion of quartz sand. The wet magnetic separator can increase the magnetic contact area of the quartz sand and reduce the inclusion of iron impurities, so that the iron removal effect is more remarkable. Therefore, in the purification process using quartz sand iron removal equipment, the wet magnetic separator is more worthy than the dry magnetic separator.
