摘　　要：通过对凤阳未磁选湿法石英砂中铁含量的测量,得出铁杂质在不同粒度石英砂中的分布规律,湿法石英砂的粒度越大(大于60目)或越小(小于180目)其铁含量越高。为了能有效地降低凤阳湿法石英砂中铁含量,提高产品的质量,石英砂生产企业应严格控制石英砂的粒度,同时对粒度大于60目和粒度小于180目的石英砂加强磁选。By means of measuring the iron content of wet quartz sand in Fengyang,we got the law of distribution of iron impurities in different particle size,the results indicated that the larger the particle of wet quartz sand（greater than 60 mesh）,or the smaller the particle of wet quartz sand（less than 180 mesh）,the higher iron content it contains.In order to effectively reduce the iron content of wet quartz sand and improve the quality of products in Fengyang,the enterprises who mainly produce quartz sand should strictly control the grain size of quartz sand and strengthen the magnetic separation for particle size of quartz sand more than 60 mesh and less than 180 mesh.
