Core Viewpoint - China's quartz resources are abundant, primarily consisting of quartzite, quartz sandstone, and vein quartz, but the proportion of high-purity quartz products is very low, leading to a heavy reliance on imports for high-purity quartz sand production [1] Group 1: Quartz Resource Characteristics - The main sources of high-purity quartz raw materials are crystal, vein quartz, and granite-type quartz, with granite-type quartz emerging as a new direction for high-purity quartz resource exploration due to its large scale, low impurities, and stable quality [1] - Research in the Altai region of Xinjiang has focused on granite-type quartz, revealing that the quartz veins are located within the Cambrian Kanas rock group, with a mineral composition that includes quartz, potassium feldspar, plagioclase, and biotite [3] Group 2: Purification Techniques - The purification process for granite-type quartz involves a combination of physical and chemical methods, including grinding, heavy separation, magnetic separation, and flotation, achieving high efficiency in separating quartz from other minerals [12] - After deep chemical purification, the total impurity content of quartz samples was reduced to 23.35 μg/g, indicating the potential for producing high-end high-purity quartz products with SiO2 content reaching 99.9983% [14] Group 3: Regional Exploration and Potential - The Luoyang Longquanping granite-type quartz deposit in Henan has been analyzed, showing a mineral composition similar to that of the Spruce Pine deposit in the U.S., with potential for high-purity quartz production [6] - The East Qinling-Dabie orogenic belt in Henan has revealed nearly 7,000 granite-type quartz veins, indicating significant exploration potential for high-purity quartz industrial deposits [7]
