The main chemical component of quartz sand is SiO2, which is accompanied by small or trace impurities. The main components of impurities are: Al2O3, Fe2O3, MgO, CaO and so on. The quartz sand purification we are going to do is to remove the impurities and finally obtain refined quartz sand or high-purity quartz sand.
