While numerous studies have explored the mineralogical characteristics and purification techniques of high-purity quartz (HPQ), discussions on impurity control during various purification processes and their applications in photovoltaics, electronics, and optics remain limited. This review delves into the adverse effects of impurities such as aluminum, iron, and sodium in the manufacturing processes of these industries, emphasizing their critical role as these impurities can degrade material performance. This paper focuses on analyzing the types of impurities found in quartz and evaluates existing purification technologies such as acid washing, ultrasonic acid washing, chlorination roasting, and calcination quenching. It highlights the limitations of current technologies in processing quartz ore and discusses the advantages of different impurity types under various technological treatments. Moreover, it explores the environmental and economic impacts of these high-purity processes, underlining the necessity for more environmentally friendly and cost-effective purification techniques. The purpose of this review is to provide a comprehensive technical and strategic framework for the use of high-purity quartz in high-tech applications, supporting future research and industrial applications in this critical material field.

Sintering dust is a typical refractory secondary iron resource. A technology‐based utilization of sintering dust as iron carbide by applying chlorination, carburization, and magnetic separation is proposed. Under optimized conditions, an electric furnace burden comprised of 83.51% Fe and 6.52% C and with a corresponding iron recovery rate of 81.21% is prepared. Meanwhile, 96.97% Pb can be removed by chlorination and magnetic separation. Furthermore, the separation mechanism is revealed using scanning electron microscopy, X‐ray powder diffraction, and optical microscopy. The results show that sodium sulfate can promote the carburizing efficiency of sintering dust, strengthen the growth of iron carbide particles, and improve the embedding relationship between iron carbide and gangue minerals, which significantly promotes the separation efficiency. The study demonstrates that the preparation of iron carbide from sintering dust using the proposed technology is a feasible method.
