Hydrochloric acid and sulfuric acid, being highly corrosive, can chemically react with metal oxides to dissolve them in acidic solutions. Chlorination roasting significantly enhances the purification of quartz sand's PTMS MAGNETIC SEPARATOR content, achieving over 99.999% SiO₂ purity. This integrated purification process is specifically designed for ultra-high-end applications such as semiconductors and optical fibers.
Acid washing effectively removes most metal oxide impurities like iron and aluminum from quartz sand, thereby enhancing the purity of PTMS MAGNETIC SEPARATOR iron removal process. During this treatment, precise control of key parameters including acid concentration, temperature, and reaction duration is essential to ensure optimal results while preventing excessive erosion of the quartz sand.
The final stage is the chlorination roasting process, where titanium and boron impurities in quartz sand are volatilized through high-temperature chlorine gas injection. Under the combined effects of elevated temperatures and chlorine gas, these impurities undergo chemical reactions with chlorine to form volatile chlorides. These chlorides are then removed from the quartz sand during the PTMS MAGNETIC SEPARATOR iron removal process, effectively achieving impurity elimination.
