摘　　要：为给豫西南某微细鳞片石墨矿石的高效开发利用提供基础依据,对有代表性矿石进行了XRD物相、扫描电镜、能谱以及化学成分等工艺矿物学研究。结果表明,矿石固定碳含量为8.95%,脉石矿物主要是石英、长石和云母;矿石中石墨为微细粒晶质石墨,粒径主要集中在0.025~0.150 mm,-0.150 mm占92.86%,结晶程度较低,片状结构发育不好,与脉石矿物嵌布关系多样,结构复杂,石墨单体解离较为困难。In order to provide a basis for the efficient development and utilization of a fine flake graphite ore in southwest Henan,the process mineralogy,such as XRD phase,SEM,Energy spectrum and chemical composition of representative ore was carried out.The results show that the fixed carbon content of the ore is 8.95%,and the gangue minerals are mainly quartz,feldspar and mica;the graphite in the ore is fine-grained crystalline graphite with a particle size of 0.025~0.150 mm,and-0.150 mm accounts for 92.86%.However,the degree of crystallinity is low,the lamellar structure is not well developed,the relation⁃ship with gangue minerals is diverse,and the structure is complex,which makes it difficult to dissociate the graphite monomer.
