摘　　要：河南省某地发现一种产于风化似斑状中粒二长花岗岩中的钾长石矿,钾长石矿主要赋存于似斑状中粒二长花岗岩全风化带和强风化带内,可以通过简单的筛选工艺选出钾长石斑晶,钾长石斑晶经过选矿后可以作为优质钾长石矿产利用。此类钾长石矿床具有矿床规模大,采矿成本低,经济效益总体较好等特点,可以作为新的钾长石矿类型开采利用。A kind of potassium feldspar ore produced in weathered porphyritic medium grained monzogranite was found in a place in Henan Province. The potassium feldspar ore mainly occurs in the fully weathered zone and strongly weathered zone of porphyritic medium grained monzogranite. The potassium feldspar phenocrysts can be selected through a simple screening process. After beneficiation, the potassium feldspar phenocrysts can be used as high-quality potassium feldspar minerals. This kind of potassium feldspar deposit has the characteristics of large scale, low mining cost and good overall economic benefits. It can be used as a new type of potassium feldspar mine.
