Some researchers used kaolin tailings to prepare low-iron quartz sand for photovoltaic glass. The invention relates to the technical field of quartz sand production, in particular to an improvement method for superfine powder tailings of quartz sand by utilizing photovoltaic glass, which comprises the steps of putting quartz sand tailings into a magnetic separator, and primarily removing. The general beneficiation process of domestic quartz sand purification has developed from "grinding, magnetic separation, washing" in the early stage to "sorting → coarse crushing → calcination → water quenching → grinding → screening → magnetic separation → flotation → acid leaching →washing. The global demand for high-purity quartz sand (HPQS), defined as silica (SiO 2) content exceeding 99. 95%, is experiencing unprecedented growth. This critical material is the backbone of high-tech industries, serving as the essential raw material for solar photovoltaic cells, semiconductor. Kaolin tailings contain a large amount of quartz resources.
