摘　　要：广西石排冲矿区钾长石矿产主要赋存于晚侏罗世斑状黑云母钾长花岗岩风化壳中,原岩结构清楚,岩石松散-半松散状。为合理利用该区域矿产资源,通过地质调查及矿石性质分析,发现其矿物成分主要为钾长石,其次为斜长石,矿石类型为风化花岗岩型长石矿,原矿w(K_(2)O+Na_(2)O)为6.62%,经筛分后净矿中w(K_(2)O+Na_(2)O)为10.67%,达到了日用陶瓷长石精矿粉合格品品质要求。Potassic feldspar minerals mainly occur in the late Jurassic porphyritic biotite potassic feldspar weathering crust in Shpaichong mining area,Guangxi Province.The protolith structure is clear and the rocks are loose and semi-loose.In order to make rational use of mineral resources in this area,through geological survey and ore property analysis,it is found that the mineral composition is mainly potassium feldspar,followed by plagioclase,and the ore type is weathered granite-type feldspar.The raw ore w(K_(2)O+Na_(2)O)is 6.62%,and the net ore w(K_(2)O+Na_(2)O)is 10.67%after screening.Therefore,the quality require⁃ments of ceramic feldspar fine powder for daily use can be met.
