Abstract: 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（K₂O+ Na₂O）is 6.62%，and the net ore w（K₂O+Na₂O）is 10.67% after screening.Therefore，the quality require⁃ ments of ceramic feldspar fine powder for daily use can be met.
