The invention relates to the technical field of quartz sand purification processing, in particular to a purification process for improving the sodium ion removal rate of high-purity quartz sand. The technology aims at solving the technical problems that when soluble sodium salt and lattice embedded state sodium (such as Al < 3 + > charge compensation type) coexist in high-purity quartz sand, removal is not thorough through a traditional technology, and precipitates are likely to be generated.
