1、高纯石英的研究意义 高纯石英是由自然界天然存在的含石英岩石中较高纯度石英作为原料矿石经工业上破 碎、煅烧、 水淬 、筛分、磁选色选、浮选、酸洗等提纯工艺生产而成的高品质石英（杨晓 勇等, 2021）。 汪灵 （2023）制定了国内高纯石英的质量标准，将 SiO2≥99.9 wt .%的 石英视为高纯石英。经过工业提纯后的高纯石英广泛应用于半导体、高温灯管、电信和光 学、太阳能硅、微电子等行业（Müller et al. , 2007; Haus , 2005）。 近年来，随着半导体、光通讯、光伏等领域市场的快速发展，作为原材料的高纯石英资 源却相对稀缺（Haus , 2005）。因此，立足国内外石英资源，根据石英原矿的包裹体特征 和提纯前后微量元素特征，对各类石英原料矿石进行高纯石英资源可利用性评价，可以发掘 石英更大的经济价值，实现矿产资源的高效利用。其中，热液脉体中结晶出来的石英因晶粒 结晶粒度粗大，易于解离，SiO2 含量高，是替代天然水晶作为加工高纯石英的理想原料矿 石（汪灵, 2019; 杨晓勇等, 2021） 2、脉石英样品手标本 从手标本看（图 1）：老挝 LW-1、津巴布韦 JBBW-1、 ...
