The invention relates to the field of quartz sand processing, in particular to a process for preparing quartz sand from quartz gravel. Comprising the following steps: S1, crushing quartz gravels into particles for subsequent treatment; s2, the crushed quartz gravel is screened, and impurities and large particles are removed; s3, the screened quartz gravels are ground, so that particles are finer and more uniform; s4, the ground quartz gravels are put into an iron removal device, and iron in the quartz gravels is removed; s5, the quartz sand is washed, residual impurities and dust are removed, and then drying treatment is conducted; s6, packaging the prepared quartz sand, and storing for later use; the ground quartz gravels can be put into the iron removal device, and iron in the quartz gravels is removed. 本发明涉及石英砂加工领域，更具体的说是一种利用石英砾石制备石英砂的工艺。包括以下步骤：S1：将石英砾石进行破碎，将其破碎成颗粒，以便后续处理；S2：将破碎后的石英砾石进行筛分，去除杂质和较大的颗粒；S3：将经过筛分的石英砾石进行研磨，使颗粒更加细致和均匀；S4：将研磨后的石英砾石放入除铁装置中，将石英砾石中的铁去除；S5：对石英砂进行洗涤，去除残留的杂质和粉尘，然后进行干燥处理；S6：将制备好的石英砂进行包装，
