摘　　要：高纯石英是高端技术领域的关键基础矿物原材料,作为找矿研究,涉及一些基础问题和关键技术需要厘清和界定。对高纯石英、高纯石英用硅质原料、纯度、关键杂质、评价指标、高纯品级等进行了界定,提出矿床成因、实验检测和选矿提纯为高纯石英用硅质原料研究中的关键技术。高纯石英用硅质原料分为两个品级:高纯硅质原料(SiO_(2)含量≥99.9%,Al含量≤700×10^(-6),(Li+Ti)含量≤200×10^(-6))和超纯硅质原料(SiO_(2)含量≥99.995%,Al含量≤35×10^(-6),(Li+Ti)含量≤10×10^(-6))。高纯石英用硅质原料应以白岗岩型、白云母伟晶花岗岩型和变质石英岩型为主攻方向,突破优质资源瓶颈。西武夷山地区是花岗岩型高纯石英用硅质原料的重要成矿区带,已发现伟晶岩型、伟晶花岗岩型、白云母伟晶花岗岩型3类花岗岩型高纯石英用硅质原料。High-purity quartz is a key mineral raw material in the high-end technology field.In the mineral exploration researches,there are still several fundamental questions and key technologies that need to be clarified and defined.The definition of high-purity quartz,silicon material for high-purity quartz,purity,key impurities,high-purity grades have been made.Meanwhile,the genesis of ore deposits,experimental testing,and ore beneficiation are key technologies in the research of silicon material for high-purity quartz were proposed.It is proposed that high-purity quartz silica raw materials can be divided into two grades:high-purity quartz silica raw materials(SiO_(2)≥99.9%,Al≤700×10^(-6),(Li+Ti)≤200×10^(-6));parity quartz silica raw materials(SiO_(2)≥99.995%,Al≤35×10^(-6),(Li+Ti)≤10×10^(-6)).High-purity quartz silica raw materials should focus on white pegmatite,white mica granite,and metamorphic quartzite,and breakthrough the bottleneck of high-quality resources.The west Wuyi mountain area is an important metallogenic belt of granite-type siliceous raw materials for high-purity quartz.Three types of granite-type siliceous raw materials for high-purity quartz,including pegmatite type,pegmatite granite type and muscovite pegmatite granite type,have been found.
