Silica sand washing plant mainly includes: quartz stone crushing and sand making, washing, grading, desliming, scrubbing, magnetic separation, flotation, acid leaching and other processes to remove the small amount or micro amount of impurities in silica sand and obtain refined silica sand or high-purity silica sand for glass, ceramics, construction, chemical and other industries.

Other Methods also need use different process:
Washing and classifying desliming
The SiO2 grade in quartz sand(silica sand) decreases by quartz sand(silica sand) size becoming finer, so washing and desliming of crude quartz sand(silica sand) is necessary before next step.
Scrubbing
Scrubbing is the way to remove film iron and impurity minerals on the surface of quartz by mechanical force and crush these mineral aggregate. The quartz sand gets further purification by classification. There are two kinds of methods rob scrubbing and mechanical scrubbing.
Flotation
The separation of mica and quartz is difficult, the effective methods: anionic collector in acid condition and anionic - cationic collector in alkaline condition. The purification of quartz sand can reach 99% after scrubbing, desliming, magnetic separation and flotation.
Acid Leaching
Dilute acid had a significant effect on removing iron and aluminum, and concentrated acid for the removal of titanium and chromium, and mixed acid for mineral impurity. Control various factors of acid leaching should be based on quartz final grade requirements, and as far as possible reduce the acid concentration, temperature and dosage to achieve quartz purification.
