Short summary
This study compares trace elements with the Spruce Pine pegmatite deposits in the United States and the pegmatite deposits in East Qinling in China to explore which types of deposits have the potential to become high-purity quartz raw material deposits. In addition, we also carried out technical purification and economic evaluation of the collected samples, aiming to provide guidance on technical purification and trace element determination of high-purity quartz deposits.

Short summary
This study evaluated quartz vein ore from the Peshawar Basin, Pakistan, for producing high-purity quartz sand. Samples were purified and the analysis revealed fluid inclusions as main impurities. Post-purification, the quartz sand showed minimal inclusions and high SiO2 content (99.997–99.999 wt %). Impurity elements like Li and Al were significantly reduced. The refined quartz sands are deemed suitable for high-purity quartz products used in industrial applications.

Short summary
This study evaluates leucogranites from the Ama Drime Massif, Dinggye, Tibet, as a potential raw material for high-purity quartz. Petrographic, geochemical, and purification analyses of two representative samples show that the rocks are mainly composed of quartz, albite, and K-feldspar. After purification, the quartz reached SiO₂ contents of 99.996 % and 99.995 %, indicating promising potential as a supplementary high-purity-quartz resource.
