石英砂除杂提纯方法的比较研究
Study on Purification Methods of Removing Impurity from Quartz
在草酸提纯法的基础上，以沙县竟成公司提供的石英砂为原料，结合不同的处理方法（如：酸浸静置、磁选、超声波等），对浸出液中的铁、铝离子浓度进行化学分析，对处理前后的样品辅以XRD、XRF、白度测定等表征手段，对比各种除杂方法的提纯效果。实验结果表明，采用超声波处理的提纯效果较佳，样品A中铁的去除率达到4.368 mg Fe/（g Quartz•L H2C2O4• h），样品B中铝的去除率达到9.4864 mg Al/（g Quartz•L H2C2O4• h）；样品的白度值明显提高，且不破坏石英砂的晶体结构。
Based on oxalic acid purification method, quartz offered by Shaxian Jingcheng Company was treated with different methods (i.e. acid leaching, magnetic separation and ultrasound). In order to compare the purifying effect of various methods, the concentration of iron and aluminum, the characterization of XRD, XRF and Whiteness were analyzed. The primary experimental results show that the effect of ultrasonic treatment is better. Sample A, the iron content decreased rate gets to 4.368 mg Fe/(g Quartz•L H2C2O4• h). Sample B, the aluminum ion content decreased rate gets to 9.4864 mg Al/(g Quartz•L H2C2O4• h). The whiteness of sample improved obviously while the crystal structure of quartz without destroying.
