Characteristics and Availability of Strategic Non-metallic Mineral Resources in Qinghai Province

Non-metallic minerals such as crystalline graphite, fluorite, high-purity quartz and boron are widely used in strategic emerging industries such as high-end equipment manufacturing, biomedicine, new materials, new energy and new generation information technology. This paper comprehensively summarizes the characteristics of strategic non-metallic mineral resources in Qinghai, and completes the analysis and evaluation of their availability by mineral types in combination with the beneficiation and purification test results of graphite, quartz, talc and garnet, and the processing technical performance of fluorite, boron ore and barite. According to the demand and development trend of lithium battery, new energy, new materials and other industries in the province for various mineral raw materials, it is considered that the five minerals of crystalline graphite, fluorite, high-purity quartz, boron ore and barite have the most development and utilization prospects. The research results will provide a basis for the development of mineral resources and the layout of related industries in Qinghai.
