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. Efficient removal is achieved through a hydrothermal dissolution-acid pickling impurity removal-flotation separation synergistic mechanism. Firstly, soluble sodium salt is dissolved out preferentially under the hydrothermal condition of 65 DEG C, so that it is avoided that in subsequent acid pickling, HF reacts with the sodium salt to generate Na2SiF6 sediment; then, an HF-HCl mixed acid system is adopted to selectively etch lattice channels at 70 DEG C and open a gas-liquid inclusion, so that embedded sodium is promoted to migrate and dissolve out; and finally, separating sodium-containing gangue (such as albite) exposed by pickling through flotation. According to the process, the hydrothermal times (2-3 times) can be dynamically adjusted according to the ore characteristics, stable production of semiconductor-grade quartz sand is achieved with low energy consumption which saves more than 30% of energy compared with a chloridizing roasting process, and the process is suitable for high-valued utilization of domestic vein quartz ore.
