Experimental study was carried out to realize comprehensive recovery of non-metallic mineral resources from granite tailings in Henan Province, and explore the feasibility of preparing high-purity quartz. The results show that the granite tailings, mainly containing minerals of plagioclase feldspar, quartz, potassium feldspar and mica, have potential to be comprehensively utilized. With a flowsheet consisting sequentially of scrubbing-magnetic separation, pre-treatment of desliming, and mica-feldspar-quartz preferential flotation, a mica concentrate with Al2O3, K2O, Na2O, SiO2 and Fe2O3 contents of 33.84%, 8.13%, 0.32%, 56.78% and 0.121%, a feldspar concentrate with Al2O3, K2O, Na2O, SiO2 and Fe2O3 contents of 15.89%, 2.16%, 10.68%, 71.06% and 0.124%, and a quartz concentrate with Al2O3, K2O, Na2O, SiO2 and Fe2O3 contents of 1.05%, 0.17%, 0.56%, 97.76% and 0.106%, respectively, can be collected. The quartz concentrate can be further purified to obtain a high-purity quartz sand with SiO2 content of 99.994%.
