The grade of SiO2 in quartz sand decreases with the finer grain size of quartz sand, and the grade of impurity minerals is the opposite. This phenomenon is especially obvious in quartz sand containing a large number of clay minerals. Therefore, the quartz sand ore before the selection is carried out. Washing and deslipping are very necessary.

Introduction. The SiO 2 system is very complex.

Quartz is one of the most common minerals in the Earth's crust. As a mineral name, quartz refers to a specific chemical compound (silicon dioxide, or silica, SiO 2 ), having a specific crystalline form (hexagonal). It is found is all forms of rock: igneous, metamorphic and sedimentary. Quartz is physically and chemically resistant to weathering.

 · In the quartz sand extraction process, because there are fewer impurities in the raw ore, the main beneficiation process is to purify and remove a small amount of impurities in quartz sand. Currently, the processes used include: classifiion and desliming, scrubbing, magnetic separation, flotation, acid leaching and so on.
