Abstract: As an important branch of natural quartz mineral resources, tripoli exhibits unique value in the fields of ceramics, glass, and high-end functional materials due to its high silicon content, fine particles, and loose structure. This paper systematically summarizes the mineralogical characteristics, geological genesis, distribution patterns, purification processes, and application fields of tripoli using popular science language, aiming to reveal the comprehensive utilization potential of this “low-profile yet powerful” siliceous resource. Tripoli is mainly formed by long-term mild superficial weathering and precipitation erosion of siliceous rocks. The deposits in China are mainly distributed in Chongqing, Jiangxi, Guizhou, and other regions, with limited resource reserves but excellent quality. The raw ore of tripoli often contains impurities such as iron, aluminum minerals, and inclusions, which require multi-process purification techniques such as scrubbing, acid leaching, and chlorination roasting to meet the needs of high-end industries. In terms of application, tripoli has been widely used in ceramics, refractory materials, and other fields: it can be added to ceramics to reduce firing temperature and defects; used in refractory materials to prepare high-density silica bricks; accelerating the melting process and reducing energy consumption in the glass industry; and enhancing the mechanical and corrosion resistance properties of polymer materials as a functional filler. Focusing on the high-quality development and utilization of tripoli resources, it would be necessary to deepen the research on metallogenic mechanism, overcome green and efficient purification technologies, and also expand its high-value-added utilization pathways. Through discussion, this paper aims to provide the public with a deep understanding of the scientific value and practical significance of this “silica treasure”, provide popular science references for its further promotion and application, and have significant implications for promoting the green and high-value utilization of quartz mineral resources and upgrading silicon-related industries.
