Abstract: In order to scientific assess and proper utilize the zeolite resources of Xinyang Shangtianti, the mineralogy characteristics of zeolite ore were investigated, using various techniques including microscopic analysis, X-ray diffraction analysis, X-ray fluorescence spectrometer analysis, scanning electron microscope and automatic mineral identification and characterization system. The results show that zeolite ore of Shangtianti has high SiO₂/Al₂O₃ ratio and the mineral species detected in zeolite ore are up to 25. Clinoptilolite is the dominant mineral specie (mineral content ranges from 20% to 80%). The crystals of clinoptilolite are well developed, show plate-like or thick plate-like structure. 90 % of the clinoptilolite crystals' size is greater than 150 μm. The monomer dissociation degree of clinoptilolite at +74 μm、-74+45 μm、-45 μm is 25.02%、27.99%、56.9%, respectively, and clinoptilolite has paragenetic relation with orthoclase, quartz and montmorillonite.
