摘　　要：该文采用化学多元素分析、粒度筛析等方法对试样进行了研究。研究表明此试样中SiO_(2)含量为98.52%,杂质Al_(2)O_(3)、Fe_(2)O_(3)含量分别为0.69%、0.084%。试验采用磨矿、分级、磁选、擦洗等多种选矿工艺方法,对其进行选矿试验研究。原矿经“棒磨-磁选-水力分级-擦洗”工艺流程选别后,获得的精矿产率为71.85%、SiO_(2)含量为99.57%、Al_(2)O_(3)含量为0.11%、Fe_(2)O_(3)含量为0.007 5%、TiO_(2)含量为0.002 1%,满足超白光伏玻璃原料的指标要求。In an experimental study on ore dressing of a vein quartz in Guangdong,we carried out the study on samples based on chemical multi-element analysis and particle size sieve analysis.The research shows that the content of SiO_(2) in the sample is 98.52%,and the content of impurity elements Al_(2)O_(3) and Fe_(2)O_(3) are 0.69%and 0.084%respectively.In the experiment,a variety of ore dressing techniques such as grinding,grading,magnetic separation,and scrubbing were used to conduct ore dressing experiments.After the raw ore is sorted through the process of“rod grinding-magnetic separation-hydraulic classification-scrubbing”,we can get the following results:the productivity of ore concentrate is 71.85%,the content of SiO_(2) is 99.57%,the content of Al_(2)O_(3) is 0.11%,the content of Fe_(2)O_(3) is 0.0075%,and the content of TiO_(2) is 0.0021%,which meet the index requirements of ultra-clear photovoltaic glass raw materials.
