我国发现高纯石英新矿种

Core Viewpoint - The Ministry of Natural Resources of China has officially recognized high-purity quartz ore as the 174th mineral resource in the country, which is crucial for strategic emerging industries such as semiconductors and photovoltaics [1][2]. Group 1: Mineral Discovery and Characteristics - High-purity quartz ore has been discovered in regions such as East Qinling in Henan and Altay in Xinjiang, characterized by a silicon dioxide (SiO2) purity of no less than 99.995% (4N5) [1][2]. - The mineral is rare in nature and is essential for applications in high-tech fields, including semiconductors and optics [1]. Group 2: Technological Advancements and Industry Development - Several domestic research institutions and enterprises have developed key technologies for rapid screening, deep purification, and targeted impurity removal of high-purity quartz, leading to the establishment of a certain scale of industrial chain support in China [2]. - The China Geological Survey and various provincial geological units have successfully produced 4N5 and even 4N8 grade products, marking a significant step towards domestic resource utilization and replacement [2]. Group 3: Policy and Strategic Planning - The Ministry of Natural Resources plans to include high-purity quartz ore in the directory of strategic mineral resources and will enhance the technical indicators and geological exploration standards for this mineral [3]. - There will be a focus on strengthening the development and utilization of high-purity quartz resources, including geological theory research and resource investigation [3].
