| 摘 要： | 作为战略性矿产资源之一,高纯石英已广泛应用于集成电路、半导体芯片、太阳能等高新技术产业中,但是能够生产高纯石英的原料矿床极为稀缺,我国尤为紧缺高纯石英原料矿。鄂东南地区是湖北省脉石英矿床的主要分布区。本文针对鄂东南付家山脉石英矿床,通过光学显微镜、扫描电子显微镜观察了脉石英的脉石矿物类型和包裹体特征,采用电感耦合等离子发射光谱法(ICP-OES)对原矿进行了微量元素分析,旨在获得付家山脉石英矿床的杂质元素特征,进而评价矿床用作高纯石英原料的潜力。结果表明,付家山脉石英矿石SiO2含量大于99.95%,杂质元素主要为Al、K、Fe、Ti、Ca等,脉石矿物主要有白云母、钾长石、铁氧化物等,流体包裹体较为发育。杂质元素分析结果表明,付家山脉石英原矿质量达到低端高纯石英标准,经传统工艺提纯后,可能具有生产中高端高纯石英的潜力。

| Abstract: | As one of the strategic mineral material, high-purity quartz has been widely used in integrated circuits, semiconductor chips, solar energy and other high-tech industries. However, raw material deposits that can be used to produce high-purity quartz are extremely scarce, especially in China. Southeastern Hubei is the main distribution area of vein quartz deposits in Hubei Province. In this paper, the gangue mineral types and inclusion characteristics of vein quartz from the Fujiashan quartz deposit in southeastern Hubei are observed by optical microscope and scanning electron microscope. The trace element concentrations of the raw quartz material are analyzed by inductively coupled plasma atomic emission spectrometry (ICP-OES) to obtain the impurity element characteristics of Fujiashan quartz deposit and evaluate the potential of the deposit as a raw material for high-purity quartz. The results show that the average content of SiO2 of the raw quartz is more than 99.95%, and the impurity elements(Al, K, Fe, Ti, Ca, etc.)mainly occur in gangue minerals such as muscovite, potassium feldspar and iron oxide, lattice-bound form and fluid inclusions. The results show that the quality of Fujiashan quartz raw ore reaches the standard of low-end high-purity quartz, and it may have the potential to produce middle-to-high end high-purity quartz after traditional purification. |
