Pure zircon sands usually appear as colorless and transparent tetrahedral prismcrystals, because of different origins, the types and quantities of impurities. It is often dyed into yellow, orange, red, brown and other colors.
It usually has a mineral paragenesis with ilmenite, rutile, monazite, xenotime in beach placer, which can be obtained through the water gravity selection, electric separation, magnetic separation and other mineral processing methods, the theoretical components are ZrO2 and SiO2, and small amount of Fe2O3, CaO, Al2O3 and other impurities. In theory, pure zicon sands contains 67.23% and 32.77% SiO2.
