摘　　要：凤阳是中国著名的石英砂生产基地,石英岩中SiO2含量高,杂质少,质量稳定。通过对凤阳石英岩的矿物组成和石英砂生产工艺的研究,深入分析了凤阳石英岩资源开发和利用的现状,指出目前凤阳石英岩加工利用方面存在的问题,并提出以下建议:对石英岩进行优矿先采,在开采过程中还要加强技术投入,对优质石英岩进一步深加工,对尾砂进行综合利用。Fengyang is a famous production base of quartz sand in China,in which the content of SiO2 in the quartzite is high,impurity is low and quality is stable.Based on the mineral composition of quartzite and the production process of quartz sand,this article analyzes the current exploitation and utilization of quartzite resource in Fengyang,then points out the problems in processing and using quartz,finally put forward suggestions as follows： the quartzite of good quality should be exploited firstly,technical inputs should be strengthened in the mining process,good quality quartzite should be deep processed,comprehensive utilization of tailings should be achieved.
