摘　　要：对河南某地SiO297．36％，Al2O30．059％，Fe2O30．20％的石英岩进行高纯化除铁试验研究，采用“磨矿-分级-磁选-介质擦洗”工艺处理后，最终石英精砂化学成份：SiO299．03％，Al2O3，0．015％，Fe2O3,0．0029％（29ppm），可满足光伏太阳能玻璃用低铁石英砂的质量要求。Abstract： A high purity iron -removing experiment for the quartzite with SiO2 97.36%, Al2O3 0. 059%, Fe2O3 0. 20% from Henan was carried out. After processed by grinding, classification, magnetic separation and scrubbing, the final chemical composition of quartzite concentrate is SiO2 99, 03%, Al2O3 0. 015%, Fe2O3 0. 0029% （29ppm）, which can satisfy the quality requirements of low - iron quartzite used for photovohaic solar glass.
