Purification technology of quartz raw materials is the key to preparing high-purity quartz products. Physical and chemical purification technologies are two major categories of quartz raw material purification. Physical method can remove almost all mineral impurities existing in monomers, while chemical deep purification can remove impurities of similar quality in the envelope and lattice, which is the key factor for preparing high-purity quartz products.
The purification technology of quartz raw materials is mainly divided into physical and chemical methods. Physical purification mainly includes rubbing, reselection, flotation, magnetic separation and color selection processes, which can remove almost all mineral impurities existing in monomers. Chemical deep purification mainly includes acid (alkali, salt) treatment and thermal treatment, which can remove impurities of similar quality in the envelope and lattice, which is the key factor for preparing high-purity quartz products.
