Flotation technology of PPM level low-iron high-purity quartz sand

The invention relates to a flotation technology of PPM level low-iron high-purity quartz sand. The flotation technology is characterized in that the quartz sand raw material is mixed and stirred through three slurry mixing barrels, a specially blended flotation reagent is added, the ore pulp is fed into a flotation machine for flotation, and fine sand and tailings are subjected to desliming and dehydration treatment, so as to obtain a low-iron high-purity fine quartz sand product and a remaining tailing product. The quartz sand flotation method is easy to achieve and simple in operation, and the flotation of quartz sand can be quickly and effectively achieved by virtue of the flotation technology and the flotation reagent provided by the invention, so that the output rate of high quality quartz sand is improved, and the production cost of high quality quartz sand is greatly reduced.
