摘　　要：为科学评价和开发利用湘东北某石英云母片岩资源,采用XRF、XRD、SEM-EDS、光学显微镜和化学定量分析等手段对石英云母片岩的矿物学特征进行了详细研究。结果表明:石英云母片岩主要由51.2%的石英、16.1%的黑云母、15.4%的白云母及6.3%的长石组成。云母矿物共生关系较为简单,云母嵌布粒度长轴方向0.1~20mm,短轴方向0.01~0.2mm;石英的嵌布粒度一般为0.05~12mm。根据矿物学特征,采用风选—形状选矿—浮选工艺,可获得有利于后续应用的不同粒径的系列化云母精矿产品,矿石中石英和长石可以综合回收利用。In order to scientifically evaluate and develop a quartz mica schist resource in northeastern Hunan,the mineralogical characteristics of quartz mica schist ore were studied in detail by XRF,XRD,SEM-EDS,optical microscope and chemical quantitative analysis.The results show that quartz mica schist is mainly composed of 51.2%quartz,16.1%biotite,15.4%muscovite and 6.3%feldspar.The symbiotic relationship of mica minerals is relatively simple,the size of mica is 0.1~20 mm in long axis direction and 0.01~0.2 mm in short axis direction.The embedded particle size of quartz is generally 0.05~12 mm.According to the mineralogical characteristics,a series of mica concentrate products with different particle sizes can be obtained by using the process of air separation-shape separation-flotation.Quartz and feldspar in the ore can be comprehensively recycled.
