This is an article in the field of process mineralogy. As the raw material of high-grade quartz products，higher-purity quartz sand has strict requirements on impurity elements．Besides that，the presence of inclusions has an important impact on its purity and performance．Based on this，the fluid inclusions in the vein quartz of western Hubei Province have been studied in detail by using X-ray diffraction，plasma atomic emission spectroscopy，optical microscope，micro temperature measurement and laser Raman spectroscopy．The results show that the content of SiO2 in the ore is beyond 99.9%，and the impurity elements are mainly Al and alkali metal elements．The inclusions in the quartz are single-phase saline solution inclusions，two-phase inclusions and containing CO2 three-phase inclusions．There is no solid inclusions in the ore．The size of inclusions is mainly concentrated in 5～25 μm．The uniform temperature is 160～270 ℃ and the salinity is less than 10.00% NaCl. As a result, the ore-forming fluid belongs to medium-low temperature and low salinity fluid.According to the analysis results of the inclusion characteristics, the ore can be used as a raw material for high-purity quartz sand after deep processing and purification． |
