Impurity Characteristics of Xiuning Xiaofu Vein Quartz Ore and Its Potential as A High-purity Quartz Raw Material
A large amount of magmatic rocks are widely exposed in the Qingyang Xiuning area,providing a significant material source for the formation of vein quartz.It is one of the main distribution areas of vein quartz deposits in Anhui Province.However,the research level of vein quartz as a high-purity quartz raw material in this area is relatively low,which to some extent restricts the quality evaluation of high-purity quartz raw materials and further geological exploration breakthroughs in the area.This article focuses on the Xiuning Xiaofu vein quartz deposit,observing the structural characteristics of vein quartz through optical microscopy,determining the main vein minerals through X-ray diffraction analysis,determining the type and composition of inclusions through transmission reflection microscopy and laser Raman analysis,analyzing the main and trace elements of the original ore using ICP-MS,obtaining the mineralogical characteristics of vein quartz and the types and contents of impurity elements.Processing and purification experiments were carried out based on the different occurrence states of impurities.After purification,the SiO2 grade of Xiuning Xiaofu vein quartz can reach 99.9972%,meeting the quality requirements of high-purity quartz raw materials.This has certain reference significance for evaluating vein quartz in the Qingyang Xiuning area of Anhui Province as a high-purity quartz raw material.
