[0002] Quartz sand is an important non-metallic mineral and a raw material for hundreds of industrial processes, primarily used in the glass, metallurgical, construction, chemical, and electronics industries. With economic development and scientific advancement, particularly the rapid growth of the photovoltaic and electronics industries, the demand for ultrapure quartz powder continues to increase, and the requirements for its deep processing are also becoming increasingly demanding.

[0003] In the production process of quartz sand, purification is an important process. Generally, flotation machines are used to purify quartz sand. The purification effect directly determines the purity and quality of quartz sand. However, the existing quartz sand only uses a stirring device to stir the mortar to achieve the purpose of flotation purification, and its purification effect is difficult to achieve the expected result.
