Assessment of Gold-Bearing Quartz Vein as a Potential High-Purity Quartz Resource: Evidence from Mineralogy, Geochemistry, and Technological Purification

High-purity quartz (HPQ) is an important material widely used in many high-tech industries. It a product processed from pure natural raw materials, so selecting suitable the key to successfully processing HPQ. Hydrothermal vein one of most likely materials be purified into HPQ because its high SiO2 content. This study focuses on evaluation potential two gold-bearing tailing resources Chibougamau (CBG) and Tianjingshan (TJS). Petrography contents impurity elements samples before after were studied by optical microscope, SEM, Raman spectrometry, XRD, LA-ICP-MS, bulk solution ICP-OES. Petrographic results reveal that major impurities are feldspar, mica, iron compounds, ankerite, rutile, silicate melt, fluid inclusions. LA-ICP-MS analysis result shows between 99.953–99.971 wt.% CBG 99.969–99.976 TJS quartz, respectively, with very low elements, except for Ca. Bulk ICP-OES demonstrates sand has total 56.8 µg·g−1, 13.1 µg·g−1 Al 6.6 Ti, 85.2 29.4 6.1 Ti. Both Ti fit lattice-bound criteria These results, impurities, hosted fluid, mineral inclusions, indicating these hydrothermal can upgraded more advanced methods. Therefore, deposits would considered as future realize efficient recovery utilization tailings improve mine economic benefits.
