摘　　要：陕西某地石英资源丰富,开展矿物学研究有利于其高值高效利用。基于偏光显微镜、ICP、XRD、EPMA等现代测试技术分析了石英砂化学成分、矿物组成、粒度分布及杂质元素赋存状态等工艺矿物学特征,确定“重选-磁选-擦洗-浮选-酸浸”提纯实验工艺流程,并进行了可选性实验研究。该石英砂原料经提纯除杂,SiO_(2)含量由99.64%提高到99.90%,杂质总含量由3395.80μg/g下降至909.85μg/g,可作为高质量石英砂用于光伏玻璃原料。It is beneficial to conduct mineralogy research on the abundant quartz sand resources located in Shaanxi Province,thereby providing high value and efficient utilization methods.Base on modern testing techniques such as polarizing microscope,ICP,XRD,EPMA,etc.,the mineralogical characteristics of quartz sand,such as the chemical composition,mineral composition,particle size distribution,and the presence of impurity elements,were analyzed.A technological process of gravity separation-magnetic separationscrubbing floating-acid leaching for purification was proposed,followed by experimental study on selectivity.The raw quartz sand was purified with the SiO_(2)being increased from 99.64% to 99.90%,while the total content of impurities being decreased from 3395.80 μg/g to 909.85 μg/g,which can be used as ahigh quality quartz sand source for photovoltaic glass.
